this is what I'm using to install packages, the only one that works is requests 

pip._internal.main(['install', 'requests'])
pip._internal.main(['install', 'lxml'])
pip._internal.main(['install', 'cssselect'])
pip._internal.main(['install', 'selenium'])

this is the error message that i get in the console

i'm fairly new to python and just coding in general, i don't really know what these errors mean, and i couldn't find anything on google that i understood, so any help at all would be appreciated.

this is in visual studio code and on python 3.7.1

    There is no reason at all that I can see to use `pip._internal.main(['install', 'requests']` and the rest. Open cmd prompt and type `pip install `. If you're new to python, it's curious that you found this fringe approach that you're using; did you have issues with the standard approach? – roganjosh Dec 01 '18 at 20:06
  • @roganjosh when i used command prompt it said that pip is not recognized so i kind of just googled a bunch of stuff and i found that, which worked for requests but not the other stuff, and i wanted to be able to use this on multiple computers easily and i this was the best way i found. – Hunter Chen Dec 01 '18 at 20:08
  • Ok, this is not the correct fix. Did you install Anaconda or just regular python? – roganjosh Dec 01 '18 at 20:09
  • @roganjosh just regular python – Hunter Chen Dec 01 '18 at 20:10

  • @phd i got it working using command prompt! i'd still like to know why this error appears though.. – Hunter Chen Dec 01 '18 at 20:15
  • Take the first of @phd links. That's the correct way to fix this. Your approach is fraught with issues. – roganjosh Dec 01 '18 at 20:15
  • @roganjosh i reinstalled python and i checked add python to environment variables and now it works, but I'd still like to know why this error appears when i run it like this. – Hunter Chen Dec 01 '18 at 20:17
  • `pip._internal` should ring alarm bells. The leading underscore is the universal python syntax for "don't use this variable or invoke this method directly". How _exactly_ it fails, I don't know, but the point is that you shouldn't be accessing it in the first place unless you _know_ what you're doing (nothing in Python is private, the best you can do is stick a "don't touch this" sign to methods and variables) – roganjosh Dec 01 '18 at 20:20
  • @roganjosh alright ill keep that in mind, thank you for your help – Hunter Chen Dec 01 '18 at 20:22

I know this is coming late, but I guess this will help someone else who is facing a similar issue.

In the path:

C:\\Users\\user\\AppData\\Local\\Temp\\pip-req-tracker-047sxufq\\b3025a26893a7657747ef91c7e8a7d138021b8a645639c56cd0046c5

The "AppData" folder and its contents are probably marked as "Hidden" and/or "Read only" by the Windows, unticking those and designating them as normal folders might help.

This is the only solution that helped me out. Please try it out and comment.
