I am getting this error: https://pastebin.com/2Xb7UN9g psutil is not pure python, and contains some extensions that need to be compiled, so your system needs to have a compiler, gcc, installed; since it's not you get "unable to execute 'x86_64-linux-gnu-gcc': No such file or directory" > Some have suggested installing the python3-dev package.

Is there a way to make this install work without installing > that package? Is that package really necessary? Does this mean my you will necessarily need to install python3-dev > virtual environments are somehow subject to what libraries are > available in my system python installation? yes, in a similar way as they are dependent on the system interpreter to create and run the venv > Is there some pip > installabel package that provides these files? some packages on PyPI provide binary releases, but psutil looks like it doesnt for linux, so you need to compile it. alternatively you can install python3-psutil on your host and then "virtualenv --system-site-packages" to use the system-available modules.
