I don't know how the distro works but pdm pinned |

@frostming yes, but for example controlling a led strip requires sudo, and so pdm should be in that environment or I will need to dance around with sudo / PATH / etc. It seems to upgrade pip and wheels helped in this case. |

Why is this closed? Is there a fix? |
|
@henri-hulski you should never mess with the system dependencies, but instead, install PDM in an isolated env. Look at the installation guide, we never recommend installing PDM into the global site-packages. Plus, it is unfair to ask for every package that has conflicts with pip's dependencies to bundle all deps with it, that is not how Python packaging works. |
|
@frostming I didn't. Actually I followed exactly the instructions and used the So it seems that the installer does't create actually a totally isolated env. |

My environment: $ pdm info && pdm info --env
PDM version: 1.10.0
Python Interpreter: /usr/bin/python3 (3.9)
Project Root: ~/web/myproject/myproject-server

}So the Python interpreter in use is the global one: |

It turns out the redistributed As a workaround, you can re-install the ~/.local/share/pdm/venv/bin/pip install -I pip |

Thank you very much. The proposed workaround (re-install the pip in the venv) has just helped me in the same situation, as described. |
