Cloud9上にpythonのモジュール(numpyなど)をインストールしようとしても、pkg_resources.VersionConflictのエラーが出る

Question

Cloud9上にpythonのモジュール(numpyなど)をインストールしようとしても、pkg_resources.VersionConflictのエラーが出る

Cloud9上にpython実行環境を構築中ですが、
モジュール（numpyなど）を入れようとしても依存関係エラーが出てしまいます。
どのように対処したら良いでしょう？アドバイス頂けると助かります。
※依存関係を調べようと、pipdeptreeを入れようとしても
同様にエラーになってしまって進められませんでした。

なお、
python3 -m pip install numpy
でインストールしようとすると、パーミッション無しでエラーになります。
