On Windows, if you do not have the optional py launcher installed (including if you installed Python through the Microsoft store), replace py with python.
For security reasons, you should verify the checksum of install-pdm.py.
It can be downloaded from install-pdm.py.sha256.
For example, on Linux/Mac:
4
curl -sSLO https://pdm-project.org/install-pdm.py
curl -sSL https://pdm-project.org/install-pdm.py.sha256 | shasum -a 256 -c -
# Run the installer
python3 install-pdm.py [options]
The installer will install PDM into the user site and the location depends on the system:
$HOME/.local/bin for Unix
$HOME/Library/Python/<version>/bin for MacOS
%APPDATA%\Python\Scripts on Windows
You can pass additional options to the script to control how PDM is installed:
10
usage: install-pdm.py [-h] [-v VERSION] [--prerelease] [--remove] [-p PATH] [-d DEP]
optional arguments:
  -h, --help            show this help message and exit
  -v VERSION, --version VERSION | envvar: PDM_VERSION
                        Specify the version to be installed, or HEAD to install from the main branch
  --prerelease | envvar: PDM_PRERELEASE    Allow prereleases to be installed
  --remove | envvar: PDM_REMOVE            Remove the PDM installation
  -p PATH, --path PATH | envvar: PDM_HOME  Specify the location to install PDM
  -d DEP, --dep DEP | envvar: PDM_DEPS     Specify additional dependencies, can be given multiple times
You can either pass the options after the script or set the env var value.

1
pip install --user pdm
Assuming you have asdf installed.
3
asdf plugin add pdm
asdf install pdm latest
asdf local pdm latest
By copying the Pyprojectx wrapper scripts to a project, you can install PDM as
(npm-style) dev dependency inside that project. This allows different projects/branches to use different PDM versions.
To initialize a new or existing project,
cd into the project folder and:
Linux/MacWindows
2
curl -LO https://github.com/pyprojectx/pyprojectx/releases/latest/download/wrappers.zip && unzip wrappers.zip && rm -f wrappers.zip
./pw --add pdm
2
Invoke-WebRequest https://github.com/pyprojectx/pyprojectx/releases/latest/download/wrappers.zip -OutFile wrappers.zip; Expand-Archive -Path wrappers.zip -DestinationPath .; Remove-Item -Path wrappers.zip
.\pw --add pdm
When installing pdm with this method, you need to run all pdm commands through the pw wrapper:
Linux/Mac/Windows
1
./pw pdm install
Uninstallation#
If you need to remove PDM from your system, you can use the following script:
Linux/MacWindows
1
curl -sSL https://pdm-project.org/install-pdm.py | python3 - --remove
1
powershell -ExecutionPolicy ByPass -c "irm https://pdm-project.org/install-pdm.py | py - --remove"
If you installed PDM using a third-party package management tool like Homebrew, you can also uninstall PDM using the tool's uninstall method, such as brew uninstall pdm.
Packaging Status#
Shell Completion#
PDM supports generating completion scripts for Bash, Zsh, Fish or Powershell. Here are some common locations for each shell:
BashZshFishPowershell
2
pdm completion bash > /etc/bash_completion.d/pdm.bash-completion # Requires root (sudo). For an alternative, see next
pdm completion bash > ~/.bash_completion # Does not require root (sudo). Installed only for your user account
2
# Make sure ~/.zfunc is added to fpath, before compinit.
pdm completion zsh > ~/.zfunc/_pdm
Oh-My-Zsh:
2
mkdir $ZSH_CUSTOM/plugins/pdm
pdm completion zsh > $ZSH_CUSTOM/plugins/pdm/_pdm
Then make sure pdm plugin is enabled in ~/.zshrc
1
pdm completion fish > ~/.config/fish/completions/pdm.fish
10
# Create a directory to store completion scripts
mkdir $PROFILE\..\Completions
echo @'
Get-ChildItem "$PROFILE\..\Completions\" | ForEach-Object {
    . $_.FullName
'@ | Out-File -Append -Encoding utf8 $PROFILE
# Generate script
Set-ExecutionPolicy Unrestricted -Scope CurrentUser
pdm completion powershell | Out-File -Encoding utf8 $PROFILE\..\Completions\pdm_completion.ps1
Virtualenv and PEP 582#
PDM offers experimental support for PEP 582 as an opt-in feature, in addition to virtualenv management. Although the Python Steering Council has rejected PEP 582, you can still test it out using PDM.
To learn more about the two modes, refer to the relevant chapters on Working with virtualenv and Working with PEP 582.
