-.Synopsis
|
|
|
-Activate a Python virtual environment for the current PowerShell session.
|
|
|
-
|
|
|
-.Description
|
|
|
-Pushes the python executable for a virtual environment to the front of the
|
|
|
-$Env:PATH environment variable and sets the prompt to signify that you are
|
|
|
-in a Python virtual environment. Makes use of the command line switches as
|
|
|
-well as the `pyvenv.cfg` file values present in the virtual environment.
|
|
|
-
|
|
|
-.Parameter VenvDir
|
|
|
-Path to the directory that contains the virtual environment to activate. The
|
|
|
-default value for this is the parent of the directory that the Activate.ps1
|
|
|
-script is located within.
|
|
|
-
|
|
|
-.Parameter Prompt
|
|
|
-The prompt prefix to display when this virtual environment is activated. By
|
|
|
-default, this prompt is the name of the virtual environment folder (VenvDir)
|
|
|
-surrounded by parentheses and followed by a single space (ie. '(.venv) ').
|
|
|
-
|
|
|
-.Example
|
|
|
-Activate.ps1
|
|
|
-Activates the Python virtual environment that contains the Activate.ps1 script.
|
|
|
-
|
|
|
-.Example
|
|
|
-Activate.ps1 -Verbose
|
|
|
-Activates the Python virtual environment that contains the Activate.ps1 script,
|
|
|
-and shows extra information about the activation as it executes.
|
|
|
-
|
|
|
-.Example
|
|
|
-Activate.ps1 -VenvDir C:\Users\MyUser\Common\.venv
|
|
|
-Activates the Python virtual environment located in the specified location.
|
|
|
-
|
|
|
-.Example
|
|
|
-Activate.ps1 -Prompt "MyPython"
|
|
|
-Activates the Python virtual environment that contains the Activate.ps1 script,
|
|
|
-and prefixes the current prompt with the specified string (surrounded in
|
|
|
-parentheses) while the virtual environment is active.
|
|
|
-
|
|
|
-.Notes
|
|
|
-On Windows, it may be required to enable this Activate.ps1 script by setting the
|
|
|
-execution policy for the user. You can do this by issuing the following PowerShell
|
|
|
-command:
|
|
|
-
|
|
|
-PS C:\> Set-ExecutionPolicy -ExecutionPolicy RemoteSigned -Scope CurrentUser
