[Mac] [Python] [Virtualenv] installation configuration and use

Installation Help documentation installation VIRTUALENV error as follows

After the check found that because the Mac native python2.7 installed under/usr/bin, but installed pycharm will be in the/usr/local/bin will have python3.0 execution files, so the local calls are basically pycharm take over.

Therefore, to py2.7 installation of the corresponding environment, you need to Pycharm to install virtalenv and virtualenvwrapper to

After the installation is complete, you can do it at the command line

• Create a virtual environment directly $ virtualenv ENV1
• Create a virtual Environment from mkvirtualenv after importing environment variables
  • $export workon_home=~/Workspaces
  • $source/usr/local/bin/virtualenvwrapper. SH
  • $mkvirtualenv env1

The python environment created in this way is 3.4.

Note: If you need to create a virtual env using your Mac's original py2.7 environment, proceed as follows:

You need to specify the installation of the PIP3 and set the working path of the virtualenvwrapper, but it is not recommended because the operating environment is py2.7

Install virtualenv virtualenvwrapper$ export virtualenvwrapper_python=/usr/local/bin//usr/local/bin/ Virtualenvwrapper. SH

Common commands:

2. List Virtual environments:

   $ lsvirtualenv -benv1env2

4. To switch between virtual environments:

   $ workon env1

6. See which packages are installed in your environment:

   $ lssitepackages

8. Enter the current environment:

   $ cdvirtualenv

10. Site-packages into the current environment:

    $ cdsitepackages$ cdsitepackages pip

12. To replicate a virtual environment:

    $ cpvirtualenv env1 env3Copying env1 as env3...

14. Exit the virtual Environment:

    $ deactivate

16. To delete a virtual environment:

    $ rmvirtualenv env2Removing env2...
