オフラインimapがpython2.7を使用するように強制する方法は？

新しいコンピュータをセットアップしてインストールしましたが、それを実行しようとすると、OfflineimapがPython3をサポートしていないため、一連のエラーが発生しますofflineimap。pip install --user offlineimap

https://github.com/OfflineIMAP/offlineimap/issues/472

2.7と3をインストールしました。

amanda@host:~$ python --version
Python 2.7.15rc1

しかし、私でもOfflineimapを強制的に使用する方法がわかりません。

すべてhttps://stackoverflow.com/questions/10919569/install-a-module-using-pip-for-specific-python-versionPythonのバージョンを指定して削除して再インストールしようとしましたが、これはそれ自体の特別な方法で息を止めます。

amanda@host:~$ python2.7 ~/.local/bin/pip install --user offlineimap
Traceback (most recent call last):
  File "/home/amanda/.local/bin/pip", line 7, in <module>
    from pip._internal import main
