Root Cause

The venv was created with --without-pip, or ensurepip is unavailable (Debian's python3-venv split package), so the new environment has no pip.

generic

中文

venv 使用 --without-pip 创建，或 ensurepip 不可用（Debian 的 python3-venv 分离包），因此新环境没有 pip。

Workarounds

  1. 95% success 
    python -m ensurepip --upgrade
python -m pip install --upgrade pip
  2. 97% success 
    sudo apt install python3-venv python3-pip
rm -rf .venv
python3 -m venv .venv
source .venv/bin/activate
python -m pip install requests

Dead Ends

Common approaches that don't work:

  1. 95% fail

    pip is the thing that is missing; the command cannot run.

  2. 80% fail

    Mixes system and venv paths, leading to subtle import and shebang issues.
