1
00:00:05,380 --> 00:00:10,150
so in this video we are going to talk through potential
issues you may have with the next

2
00:00:10,150 --> 00:00:13,320
section of the course when we need to
make sure that Python or some

3
00:00:13,320 --> 00:00:17,280
of the tools of Python are working
on the command line so what you need to

4
00:00:17,280 --> 00:00:21,190
do first on your Windows machine is you
need to open your command your command

5
00:00:21,190 --> 00:00:26,600
prompt and you normally click on the Windows
prompt the Windows button in the

6
00:00:26,600 --> 00:00:32,189
bottom left hand corner of your screen and
click on the run option so you select

7
00:00:32,189 --> 00:00:36,170
Run and a little window where you can
type in

8
00:00:36,170 --> 00:00:41,790
cmd for command prompt an open that and
you should get a little black screen pop up

9
00:00:41,790 --> 00:00:45,990
and if you can't find that just do a
search for command prompt so basically

10
00:00:45,990 --> 00:00:51,270
when I opened it up and I'm gonna do is
show you a screen where the command

11
00:00:51,270 --> 00:00:55,200
isn't working so if you get a screen like this
on the screen and you can see it got my

12
00:00:55,200 --> 00:01:01,150
windows open at the moment and notice how I have
typed in the commands pip I

13
00:01:01,150 --> 00:01:04,019
pressed enter and I got pip is not
recognized as an internal or external

14
00:01:04,019 --> 00:01:09,220
command so try doing that and if you get the
error get the error that says that it's

15
00:01:09,220 --> 00:01:13,760
not working then you need to follow the
instructions here to modify your Python

16
00:01:13,760 --> 00:01:18,630
installation now this is a assuming that
you've actually gone ahead and installed

17
00:01:18,630 --> 00:01:23,070
Python and obviously if got to this stage of
course presumably have done that if by

18
00:01:23,070 --> 00:01:28,980
chance you haven't installed the full Python
installation before you haven't got

19
00:01:28,980 --> 00:01:32,960
it running in IntelliJ then watch
towards the end of this video and I'll

20
00:01:32,960 --> 00:01:34,960
take you through the new installation

21
00:01:34,960 --> 00:01:38,570
but I am going to assume that you've basically gone
through the installation but you are still

22
00:01:38,570 --> 00:01:41,850
getting an error and will need to get
this pip command working so we're going

23
00:01:41,850 --> 00:01:43,300
to show you what to do

24
00:01:43,300 --> 00:01:46,980
the first thing you need to do is you
need to open up your Python

25
00:01:46,980 --> 00:01:51,240
installation again so double click the
file that you downloaded for Python and

26
00:01:51,240 --> 00:01:54,990
once you do that you should come up with this
modified set up and one you can also do

27
00:01:54,990 --> 00:01:58,990
which I won't show on the screen but you
can go into the Windows setup and you

28
00:01:58,990 --> 00:02:04,390
can come into the uninstall program
options select Python and you should have

29
00:02:04,390 --> 00:02:08,840
an option to modify so if you do get that
you get the screen to come up like this you

30
00:02:08,840 --> 00:02:12,000
wanna click on modify so you don't want to
click on uninstall

31
00:02:12,000 --> 00:02:16,130
click on modify and once you do that you
get this next screen you should get a screen

32
00:02:16,130 --> 00:02:18,760
that looks like that so what you want to do
is make sure that

33
00:02:18,760 --> 00:02:24,120
all those options are ticked
documentation pip tcl / TK and IDLE and

34
00:02:24,120 --> 00:02:27,750
Python tests suite so basically have everything ticked on the screen and if it has

35
00:02:27,750 --> 00:02:31,570
other options there now that you don't
see on the screen shots that is different on

36
00:02:31,570 --> 00:02:32,760
your machine

37
00:02:32,760 --> 00:02:37,110
have those ticked as well and click on Next what
should do is get a screen that looks very

38
00:02:37,110 --> 00:02:42,210
similar to this and make sure that the
options I've shown are selected at

39
00:02:42,210 --> 00:02:46,900
the very least associate files with Python
create shortcuts and add Python into

40
00:02:46,900 --> 00:02:51,370
environment variables so those are the important
ones particularly that third one add Python to

41
00:02:51,370 --> 00:02:54,950
environment variables because that's
actually how we get it to work

42
00:02:54,950 --> 00:02:58,710
so that when you type pip it will find the path to Python on

43
00:02:58,710 --> 00:03:02,740
your machine so without doing that you
are not going to be able to get it to work so make sure

44
00:03:02,740 --> 00:03:06,990
you select at the very least that option add Python to environment variables and if it

45
00:03:06,990 --> 00:03:10,870
happens to be worded slightly different
if it uses the Path or something like

46
00:03:10,870 --> 00:03:11,330
that

47
00:03:11,330 --> 00:03:16,680
select that option and once you've done that
click on install button as you see on the screen

48
00:03:16,680 --> 00:03:20,370
their and what you'll do you find that
it'll be fairly quick and it'll come up

49
00:03:20,370 --> 00:03:25,070
and say modification was successful modify was
successful at that point you finish the

50
00:03:25,070 --> 00:03:29,370
modification of your existing Python
installation and now we can go back

51
00:03:29,370 --> 00:03:33,210
and tests if our pip commands works again
so going back and show you and do

52
00:03:33,210 --> 00:03:37,010
that so now when you type pip you should
get something like this on-screen if you

53
00:03:37,010 --> 00:03:39,900
type pip instead of getting that to unknown
command that we got at the start of

54
00:03:39,900 --> 00:03:43,820
the video you should get something like
that shows that it's working and

55
00:03:43,820 --> 00:03:47,960
if you've got this and pip and you've
got that coming up on your screen your

56
00:03:47,960 --> 00:03:52,540
good to go and you can finish the video
now and move on to the next video now if

57
00:03:52,540 --> 00:03:56,150
you are at the stage where you are
installing this for the first time then

58
00:03:56,150 --> 00:03:59,370
continue watching but again if you've
got it working you've already had it

59
00:03:59,370 --> 00:04:02,260
installed and you follow these options
and it's working

60
00:04:02,260 --> 00:04:04,980
you don't need to watch the rest of the
video but for everyone else I'm gonna

61
00:04:04,980 --> 00:04:09,760
show you how to go about it on a new
installation on Windows of Python so

62
00:04:09,760 --> 00:04:12,990
once you've downloaded it for the first
time you get a screen similar to this

63
00:04:12,990 --> 00:04:19,120
and important thing I'm going to get you
to do is in the next screen slide is to

64
00:04:19,120 --> 00:04:24,370
click on the Add Python 3.5 on the path down
the bottom of the screen and that's very

65
00:04:24,370 --> 00:04:27,700
important to actually to add and that's
going to be how this will actually work

66
00:04:27,700 --> 00:04:31,260
for you without having to go through the
modification so click on that you

67
00:04:31,260 --> 00:04:32,170
should have a screen some

68
00:04:32,170 --> 00:04:35,340
like that once its clicked on that and
then moving on the next thing to do is

69
00:04:35,340 --> 00:04:39,480
to click on Customize installation so
selecting that option as you can see

70
00:04:39,480 --> 00:04:43,460
on the screen once you do that once you click
on customize installation you will get the

71
00:04:43,460 --> 00:04:46,850
screen that I'm just about to show you
now and it will come up with all these

72
00:04:46,850 --> 00:04:50,020
options so basically you want to select
everything on the screen that you can

73
00:04:50,020 --> 00:04:54,110
and if your screen looks slightly different to this
maybe you got a different version of python

74
00:04:54,110 --> 00:04:58,240
at some point in the future from when I
recorded this video just select

75
00:04:58,240 --> 00:05:01,540
everything on screen it doesn't really
matter but you wanna make sure at the very

76
00:05:01,540 --> 00:05:06,030
least that pup installed pip is the one
that we're gonna be using but it won't

77
00:05:06,030 --> 00:05:09,200
hurt to have everything else installed and it's
probably the best thing to do so click

78
00:05:09,200 --> 00:05:13,430
on all those options and click on Next
down the bottom of the screen once you

79
00:05:13,430 --> 00:05:16,620
do that you get a screen that looks very
similar to this now you can go ahead and

80
00:05:16,620 --> 00:05:19,560
click on install for all users if you
want and you can click on some of the

81
00:05:19,560 --> 00:05:20,460
other options

82
00:05:20,460 --> 00:05:25,410
the one that you really must click is add Python to
environment variables that's the

83
00:05:25,410 --> 00:05:29,400
one that will actually enable this
command to work so that we can actually

84
00:05:29,400 --> 00:05:34,150
use that command line option and the install
for all users is also optional and

85
00:05:34,150 --> 00:05:39,160
it won't hurt to click on associated files with
Python and create shortcuts really don't

86
00:05:39,160 --> 00:05:42,790
need to worry about pre compile standard
standard library and download debugging symbols and

87
00:05:42,790 --> 00:05:46,100
download debug libraries they are only
optional it is not something you need to worry

88
00:05:46,100 --> 00:05:51,500
about and once you do that click on
install what you'll see is you get a screen

89
00:05:51,500 --> 00:05:55,240
similar to this loading on the screen
and that will go ahead and install

90
00:05:55,240 --> 00:05:58,080
Python so it will take a few minutes to
actually go through and finish the

91
00:05:58,080 --> 00:06:02,290
installation and when its finally done you
get a screen similar to that set up was

92
00:06:02,290 --> 00:06:05,880
successful and you be able to click on close and you'll be good to go

93
00:06:05,880 --> 00:06:10,230
and go ahead and configure Python in IntelliJ and one other thing you can

94
00:06:10,230 --> 00:06:14,040
do just to double check is you can open a
command prompt and I mention how to do

95
00:06:14,040 --> 00:06:17,180
at the start of the video click on that
in type in pip

96
00:06:17,180 --> 00:06:20,390
and you should get this sort of output
something along those lines should work

97
00:06:20,390 --> 00:06:24,740
and if it doesn't work it means probably
you didn't click on the path environment

98
00:06:24,740 --> 00:06:28,180
variables option and if necessary that
still not working

99
00:06:28,180 --> 00:06:32,720
reboot the computer and it
should the work so that's it that's the

100
00:06:32,720 --> 00:06:37,230
installation options for Windows so at
this point you can now move on to the

101
00:06:37,230 --> 00:06:37,670
next video
