How to install a package for specific version on python on windows 10?
问题 I currently have Python 3.7.4(64 bit) and Python 3.6.6(64 bit) on a Windows 10 64 bit laptop with both versions in my system environment variables(path). I previously only had 3.7 and installed 3.6 to use pocketsphinx , and now I want to upgrade PyAudio of my 3.6. doing pip install --upgrade pyaudio is upgrading the pyaudio of 3.7. So, how do i upgrade(or even install) packages of specific python versions on a windows machine? Here's also what I've tried: python-3.6.6 pip install --upgrade
