使用Python 3.6在Raspberry Pi 3 Model B上安装virtualenvwrapper

Question

I have been trying to download/install virtualenvwrapper on a Raspberry Pi 3 Model B, but I get an error message when using the command "source ~/.profile" in the terminal. I am trying to install OpenCV with python 3.6, but I need to set up virtualenvwrapper. The error I get when I run "source ~/.profile" is:

/usr/bin/python: No module named virtualenvwrapper
virtualenvwrapper.sh: There was a problem running the initialization hooks.

If Python could not import the module virtualenvwrapper.hook_loader,
check that virtualenvwrapper has been installed for
VIRTUALENVWRAPPER_PYTHON=/usr/bin/python and that PATH is
set properly.

I am following this online guide: https://www.pyimagesearch.com/2017/09/04/raspbian-stretch-install-opencv-3-python-on-your-raspberry-pi/

Any help would be appreciated, thanks in advance.

Answer 1

设法修复它，不得不重写“〜/ .profile”。

Answer 2

Change

VIRTUALENVWRAPPER_PYTHON=/usr/bin/python

to

VIRTUALENVWRAPPER_PYTHON=/usr/local/bin/pythonx.x

( xx is the Python version).
