Root Cause

The venv was created without pip. This happens on Debian/Ubuntu when python3-venv is not installed, or when venv is created with --without-pip, or on some minimal Docker images.

generic

中文

创建 venv 时未包含 pip。这发生在 Debian/Ubuntu 上未安装 python3-venv 时，或使用 --without-pip 创建 venv 时，或某些最小化 Docker 镜像中。

Workarounds

  1. 95% success 
    rm -rf .venv && python3 -m venv .venv && source .venv/bin/activate && python -m pip --version
  2. 90% success 
    python -m ensurepip --upgrade
  3. 92% success 
    sudo apt update && sudo apt install python3-venv python3-pip

Dead Ends

Common approaches that don't work:

  1. 95% fail

    pip is not available to install itself; the module is missing.

  2. 85% fail

    Installs pip for the system interpreter, not inside the venv.
