新しいpythonインストールにpipをインストールしようとしています。プロキシ エラーで立ち往生しています。またはのバグのように見えますget-pipかurllib3??

質問は、ここで説明されているように CNTLMをセットアップするという苦労をしなければならないのですか、それとも近道がありますか?

get-pip.py ドキュメントには、オプションを使用--proxy="[user:passwd@]proxy.server:port"してプロキシと関連する認証を指定すると書かれています。しかしurllib3、「:」が原因で、「myusr」をURLスキームとして解釈するため、pipはすべてをそのまま渡すようです(?)。

usrname とパスワードを指定せずにコマンドを実行すると正常に動作しますが、プロキシは認証が必要であると言ってリクエストを拒否します ("407 authenticationrequired")。

簡単に調べてみましたurllib3\poolmanager.pyが、ユーザー名/パスワードとは何の関係もないようです。

これは、URL のスキームについて不平を言っています (これurlparseは であると理解していますmyusr)。代わりに次のことを行う必要があります。

get-pip.py --proxy http://myusr:mypswd@111.222.333.444:80
