How to pass an environment variable as a command line parameter in Run/Debug configuration in PyCharm?

I am trying to learn PyCharm, need to pass an environment variable as a command line parameter to my process, e.g. execute an equivalent of myScript.py -u $myVar on Linux, or myScript.py -u %myVar% on Windows.

How do I specify that in the PyCharm configuration? I don't want my script to depend on the name myVar, just on the content of that environment variable.

Solution

  • in PyCharm Run/Debug configuration for "Script Parameters:" Enter 

    -u ${myVar}

    Note: This will work only for existing env. variables but not for env. variables that you set up in the PyCharm Run/Debug configuration. For that to work, you will need to look into "Before Launch" configuration
