Why can't I install vpython from terminal?


I tried to install vpython from the terminal with the command 'pip install vpython', but it throws me this error. I have python 3.8.9 and windows 7, 32 bits. I also tried installing other libraries like numpy, and I did it successfully.

  note: This error originates from a subprocess, and is likely not a problem with pip.

I tried to put PATH and I also installed cargo, because it threw me another error. I expect to install vpython from the terminal with pip successfully


Solution

  • You are using python 32bit, you should use 64bit one instead. Uninstall your 32bit version and install 64bit. I believe that your problem would be solved.
