How to leave exit deactivate a Python virtualenv

Question

I m using virtualenv and the virtualenvwrapper  I can switch between virtualenv s just fine using the workon command    me mymachine    workon env1  env1 me mymachine    workon env2  env2 me mymachine    workon env1  env1 me mymachine       How do I exit all virtual machines and work on my real machine again  Right now  the only way I have of getting back to me mymachine    is to exit the shell and start a new one  That s kind of annoying  Is there a command to work on  nothing   and if so  what is it  If such a command does not exist  how would I go about creating it

Usually  activating a virtualenv gives you a shell function named     deactivate   which puts things back to normal   I have just looked specifically again at the code for virtualenvwrapper  and  yes  it too supports deactivate as the way to escape from all virtualenvs   If you are trying to leave an Anaconda environment  the command depends upon your version of conda  Recent versions  like 4 6  install a conda function directly in your shell  in which case you run   conda deactivate   Older conda versions instead implement deactivation using a stand-alone script   source deactivate

I had the same problem while working on an installer script  I took a look at what the bin activate this py did and reversed it   Example       usr bin python   - - coding  utf-8 - - import os import sys    Path to virtualenv venv path   os path join   home    sixdays     virtualenvs    test32      Save old values old os path   os environ  PATH   old sys path   list sys path  old sys prefix   sys prefix   def deactivate          Change back by setting values to starting values     os environ  PATH     old os path     sys prefix   old sys prefix     sys path  0    old sys path     Activate the virtualenvironment activate this   os path join venv path   bin activate this py   execfile activate this  dict   file   activate this       Print list of pip packages for virtualenv for example purpose import pip print str pip get installed distributions       Unload pip module del pip    Deactivate switch back to initial interpreter deactivate      Print list of initial environment pip packages for example purpose import pip print str pip get installed distributions      I am not 100  sure if it works as intended  I may have missed something completely

I found that when within a Miniconda3 environment I had to run   conda deactivate   Neither deactivate nor source deactivate worked for me

Using the deactivate feature provided by the venv s activate script requires you to trust the deactivation function to be properly coded to cleanly reset all environment variables back to how they were before    taking into account not only the original activation  but also any switches  configuration  or other work you may have done in the meantime   It s probably fine  but it does introduce a new  non-zero risk of leaving your environment modified afterwards   However  it s not technically possible for a process to directly alter the environment variables of its parent  so we can use a separate sub-shell to be absolutely sure our venvs don t leave any residual changes behind     To activate     bash --init-file PythonVenv bin activate   This starts a new shell around the venv  Your original bash shell remains unmodified    To deactivate     exit OR  CTRL   D    This exits the entire shell the venv is in  and drops you back to the original shell from before the activation script made any changes to the environment      Example    user computer     echo  VIRTUAL ENV No virtualenv    user computer     bash --init-file PythonVenv bin activate   PythonVenv   user computer     echo  VIRTUAL ENV  home user PythonVenv   PythonVenv   user computer     exit exit   user computer     echo  VIRTUAL ENV No virtualenv

To activate a Python virtual environment    cd   python-venv     bin activate   To deactivate    deactivate

User · Answer

Since the deactivate function created by sourcing   bin activate cannot be discovered by the usual means of looking for such a command in   bin  you may wish to create one that just executes the function deactivate   The problem is that a script named deactivate containing a single command deactivate will cause an endless loop if accidentally executed while not in the venv  A common mistake   This can be avoided by only executing deactivate if the function exists  i e  has been created by sourcing activate       bin bash  declare -Ff deactivate   amp  amp  deactivate

It is very simple  in order to deactivate your virtual env  If using Anaconda - use conda deactivate If not using Anaconda - use source deactivate

User · Answer

Use     deactivate    If this doesn t work  try     source deactivate   Anyone who knows how Bash source works will think that s odd  but some wrappers workflows around virtualenv implement it as a complement counterpart to source activate  Your mileage may vary

I use zsh-autoenv which is based off autoenv       zsh-autoenv automatically   sources  known whitelisted   autoenv zsh files  typically used in   project root directories  It handles  enter  and leave  events    nesting  and stashing of variables  overwriting and restoring     Here is an example     cd dtree  Switching to virtual environment  Development tree utiles  dtree feature task24     cat  autoenv zsh          Autoenv  echo -n  Switching to virtual environment    printf   e 38 5 93m s e 0m n   Development tree utiles  workon dtree   eof dtree feature task24     cat  autoenv leave zsh  deactivate   So when I leave the dtree directory  the virtual environment is automatically exited    Development tree utiles  is just a name    No hidden mean linking to the Illuminati in here
