問題の原因と解決法

これは、要求ではなく、タワー-CLIのようです。あなたは、要求を再インストールしてみてくださいと表示urlib3には、次の手順に従いできます

# sudo pip uninstall requests
# sudo pip uninstall urllib3
# sudo yum remove python-urllib3
# sudo yum remove python-requests

上記のすべてのライブラリことを確認するには、次のコマンドを実行することにより：

# rpm -qa | grep requests 
# pip freeze | grep requests

さて、これらのパッケージをインストールyumを使用しました：

# sudo yum install python-urllib3
# sudo yum install python-requests
