パスの確認

Pythonモジュールのimportができなくなったときの対処記録に従ってPathの追加までやってみる。

pythonが探索するパス

>>> import sys
>>> sys.path
['', '/usr/lib/python38.zip', '/usr/lib/python3.8', '/usr/lib/python3.8/lib-dynload', '/home/USERNAME/documents/manzai/venv/lib/python3.8/site-packages']

requests

(venv)$ pip show requests

WARNING: pip is being invoked by an old script wrapper. This will fail in a future version of pip.
Please see https://github.com/pypa/pip/issues/5599 for advice on fixing the underlying issue.
To avoid this problem you can invoke Python with '-m pip' instead of running pip directly.
Name: requests
Version: 2.24.0
Summary: Python HTTP for Humans.
Home-page: https://requests.readthedocs.io
Author: Kenneth Reitz

Location: /usr/local/lib/python3.8/dist-packages
Requires: chardet, idna, urllib3, certifi
Required-by: httpie

/usr/local/lib/python3.8/dist-packagesにインストールされている。
このディレクトリはPythonの探索範囲に入っていないのでPathを追加。

>>> sys.path.append('/usr/local/lib/python3.8/dist-packages')

>>> import requests
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
  File "/usr/local/lib/python3.8/dist-packages/requests/__init__.py", line 43, in <module>
    import urllib3
ModuleNotFoundError: No module named 'urllib3'

今度はurllib3がないと言われた。

解決

$ sudo pip install requests -t /usr/lib/python3.8

/usr/lib/python3.8 にrequestsをインストールで行けた!!
