Root Cause

pip installed into a different interpreter/site-packages than the one running the code (e.g. `pip` vs `python -m pip`, or a mismatched venv), so the import path does not include the install location.

generic

中文

pip 安装到了与运行代码不同的解释器/site-packages（例如 `pip` 与 `python -m pip` 不一致，或 venv 不匹配），因此导入路径不包含安装位置。

Workarounds

  1. 95% success 
    Always install via the target interpreter: `python -m pip install requests`, and confirm with `python -c 'import sys; print(sys.executable)'`.
  2. 90% success 
    Check which pip: `which pip` vs `python -m pip --version`; recreate the venv and activate it before installing.

Dead Ends

Common approaches that don't work:

  1. 90% fail

    Installs into the same wrong interpreter again.

  2. 60% fail

    Fragile and breaks when the environment changes.
