.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
|
||||
|
||||

.Description
|
||||
Get-PyVenvConfig parses the values from the pyvenv.cfg file located in the
|
||||
given folder, and returns them in a map.
|
||||
|
||||
For each line in the pyvenv.cfg file, if that line can be parsed into exactly
|
||||
two strings separated by `=` (with any amount of whitespace surrounding the =)
|
||||
then it is considered a `key = value` line. The left hand string is the key,
|
||||
the right hand is the value.
|
||||
|
||||
If the value starts with a `'` or a `"` then the first and last character is
|
||||
stripped from the value before being captured.
|
||||
|
||||
.Parameter ConfigDir
|
||||

pip is the `package installer`_ for Python. You can use pip to install packages from the `Python Package Index`_ and other indexes.
|
||||
|
||||
Please take a look at our documentation for how to install and use pip:
|
||||
|
||||
* `Installation`_
|
||||
* `Usage`_
|
||||
|
||||
We release updates regularly, with a new version every 3 months. Find more details in our documentation:
|
||||
|
||||
* `Release notes`_
|
||||
* `Release process`_
|
||||
|
||||
In 2020, we're working on improvements to the heart of pip. Please `learn more and take our survey`_ to help us do it right.
|
||||
|
||||
If you find bugs, need help, or want to talk to the developers, please use our mailing lists or chat rooms:
|
||||
|
||||
* `Issue tracking`_
|
||||
* `Discourse channel`_
|
||||
* `User IRC`_
|
||||
|
||||
If you want to get involved head over to GitHub to get the source code, look at our development documentation and feel free to jump on the developer mailing lists and chat rooms:
|
||||
|
||||
* `GitHub page`_
|
||||
* `Development documentation`_
|
||||
* `Development mailing list`_
|
||||
* `Development IRC`_

|

# 2.7, pip3.3 on Python 3.3, etc. But these entry points are baked into

# the wheel metadata at build time, and so if the wheel is installed with
|
||||
# a *different* version of Python the entry points will be wrong. The
|
||||
# correct fix for this is to enhance the metadata to be able to describe
|
||||
# such versioned entry points, but that won't happen till Metadata 2.0 is
|
||||
# available.
|

# In the meantime, projects using versioned entry points will either have

# incorrect versioned entry points, or they will not be able to distribute

# "universal" wheels (i.e., they will need a wheel per Python version).

# we need to use universal wheels. So, as a stopgap until Metadata 2.0, we

# override the versioned entry points in the wheel and generate the

# correct ones. This code is purely a short-term measure until Metadata 2.0
