Ubuntu: 使用Python虚拟环境

You probably want to work in a virtualenv :

sudo pip3 install --upgrade virtualenv
  
  

Or if you prefer you can install virtualenv using your favorite packaging
system. E.g., in Ubuntu:

  
  
sudo apt-get update
sudo apt- get install virtualenv
  
  

Then work on the virtual_env:

  
  
cd $my_work_dir
virtualenv my_env
. my_env/bin/activate
  
  

Or you can specify the Python Version:

virtualenv --no-site-packages --python=python3.5 my_env
  
  

Exit the virtual_env:

deactivate
  
  

Delete the virtual_env:

rm -r my_env
