Root Cause

Package was installed into a different Python interpreter/site-packages than the one running the script (e.g., pip vs python3, or a virtualenv not activated).

generic

中文

包被安装到了与运行脚本不同的 Python 解释器/site-packages 中（例如 pip 与 python3 不同，或虚拟环境未激活）。

Workarounds

  1. 95% success 
    python -m pip install requests  # use the same python that runs your script
  2. 90% success 
    python -c "import sys; print(sys.executable, sys.path)"
python -m pip show requests

Dead Ends

Common approaches that don't work:

  1. 70% fail

    Installs into the system Python, not the active interpreter, worsening the mismatch.

  2. 60% fail

    Does not fix the interpreter mismatch and breaks when environments change.
