pip install requirements.txtがAssertionErrorで失敗する：卵のリンクがインストールされた場所と一致しない

Question

私はライブラリとアプリケーションの両方であるPython/C++プロジェクトに取り組んでいます。私は（これはセカンドランである）を2回私に次のエラーを与える

$ pip install -r requirements.txt 

を実行している問題を抱えている：私はできるだけそれとして何回も実行する必要が

$ pip install -r requirements.txt

pip installなるためMakefileの一部であるか、アプリケーションのエンド・ユーザーの生活を楽にします。 この問題では解決策へのパスがなく、one postしか見つかりませんでした。

Answer 1

これは、誤った場所にmyProject.egg-infoフォルダがあり、Pipがアンインストールしようとしたときに転倒するように見えることが原因で起こっていました。私はこれを削除しました。pip install -r requirements.txtであり、指定された正しい場所にフォルダがインストールされています。
