先日に引き続きpipでエラー。今回はOpenSSLをインストールすることにより解消した。
現象
pipを実行するとSSLのWARNINGが出力され、インストール自体はERRORとなる
C:\Users\xxxxx>py -m pip install python-pptx –user

原因
不明。前回pipを実行してからの変更点として心当たりがあるのは
- Windows Update(20H2)の適用
- Anacondaの再インストール
どちらも原因として考えられそうだがよく分からない。Windows Updateを戻すのは現実的ではない(現象が回復したとして、ずっとWindowsUpdateを適用しないわけにはいかない)し、Anacondaを再インストールしたのは文字化けを解消するため。上記環境は変えないまま現象を改善する必要がある。
試したこと
信頼済みサイト設定
下記オプションを指定して解消した事例があったので試してみた。
- –trusted-host pypi.python.org
- –trusted-host files.pythonhosted.org
- –trusted-host pypi.org
C:\Users\xxxxx>pip install –trusted-host pypi.org –trusted-host pypi.python.org –trusted-host files.pythonhosted.org python-pptx

駄目。
ファイアーウォール無効化
とりあえず原因の切り分けのため一時的にWindowsファイアーウォールを無効化してみた。
が、駄目。
コマンドプロンプトを管理者権限で起動
全然駄目。
解消
OpenSSLを手動インストール後にリトライしてみた。

WARNINGもなく無事完了。しかしなんで急に失敗するようになったんだろうか。
