This means that the script will run with that interpreter regardless of the In order to achieve this, scripts installed into virtual environments haveĪ “shebang” line which points to the environment’s Python interpreter, Should be runnable without activating it. You don’t specifically need to activate a virtual environment,Īs you can just specify the full path to that environment’sįurthermore, all scripts installed in the environment New in version 3.8: PowerShell activation scripts installed under POSIX for PowerShell Core ( must be replaced by the path to the directory The invocation of the activation script is platform-specific Python will invoke the environment’s Python interpreterĪnd you can run installed scripts without having to use their full path. This will prepend that directory to your PATH, so that running Sys.prefix != sys.base_prefix to determine if the current interpreter isĪ virtual environment may be “activated” using a script in its binary directory Point to those of the base Python used to create the environment.
