I'm trying to upgrade python's pip from version 19.3.1 to 20.0.2. Python is on version 3.8 When I enter "python -m pip install --upgrade pip" to update pip all I get is the error message:

"ERROR: Exception:

WARNING: You are using pip version 19.3.1; however, version 20.0.2 is available.
You should consider upgrading via the 'python -m pip install --upgrade pip' command."

I've tried manually updating pip, reinstalling to the newest version of python 3.8.2, uninstalling python then installing again. With no success. Pip also isn't installing new packages either. I hope I have included enough to solve my problem.

  • Try: `python -m pip install -U pip` – Alex Susanu Apr 18 '20 at 08:21
  • Python wasn't recognised as a command but when i changed i to py it came up with the same error @AlexSusanu – Campbell Skene Apr 18 '20 at 08:26
  • `python` not being recognised as a command suggests something wrong with your `python` installation. Have you tried running a simple code or reinstalling `python`? – Cibin Joseph Apr 18 '20 at 08:35
  • Can you do a `where python` and `where pip` – Alex Susanu Apr 18 '20 at 08:36
  • If i type "py" into cmd it runs python so its working somehow? @CibinJoseph – Campbell Skene Apr 18 '20 at 08:39
  • The `py` command is a wrapper to select any of the python versions. It is always better to explicitly specify which version you'd like to run the program with; by using `py -2` or `python3` or so on. Take a look at the documentation or https://stackoverflow.com/questions/32742093/how-to-access-python-from-command-line-using-py-instead-of-python to see how `py` works. And finally, ensure you have pip installed for that *same* python version. – Cibin Joseph Apr 18 '20 at 08:43
  • @Prudhvi when i type the pip command straight into cmd it says that pip is not recognized and when i enter python from cmd then type the pip command it says that install which is in the pip command isn't recognized. – Campbell Skene Apr 18 '20 at 08:49
  • @AlexSusanu where python and where pip doesn't work – Campbell Skene Apr 18 '20 at 08:55
  • I think i have fixed it, I entered py -m pip install --user --force-reinstall -U pip into cmd and it says it has successfully updated – Campbell Skene Apr 18 '20 at 09:01
  • Thankyou for those who contributed – Campbell Skene Apr 18 '20 at 09:08
