Fatal error in launcher: Unable to create process using “file path1” file path2" : The system cannot find the file specified

问题

I am trying to use different versions of Python on my Windows pc and I'm getting this error when using pip:

Fatal error in launcher: Unable to create process using '"c:\users\ryanm\appdata\local\programs\python\python38\python.exe" "C:\Python38\Scripts\pip.exe" ': The system cannot find the file specified.

I understand that this might mean there's two PATH to each of those locations so it's confused, but c:\users\ryanm\appdata\local\programs\python\python38\python.exe doesn't even exist on my computer nor in my PATH.

Output of where python is:

C:\Python38\python.exe`

Here is the PATH in readable format

C:\Program Files\Intel\WiFi\bin\

回答1:

it seems like python team may have implemented some secure measures. The new method now is just to prefix python -m before your commands.

Let's say you are trying to install pygame (any package) with pip. For that, you'll use

python -m pip install pygame //Or any package name

Also, upgrading pip and all other commands will also use the same command structure:

pythom -m pip install --upgrade pip
