简短版：你正在混合Ubuntu的Python打包版本（ / usr / bin / python ）以及本地构建和安装的版本（ / usr / local / bin / python ）。

Short version: You're mixing Ubuntu's packaged version of Python (/usr/bin/python) and a locally built and installed version (/usr/local/bin/python).

长版：

• 您使用 apt-get install python -paramiko 将Ubuntu的官方Paramiko软件包安装到 /usr/lib/python2.7/dist-p ackages 。


• 您使用（我假设）Ubuntu的 pip 版本，安装到 /usr/local/lib/python2.7/dist-packages 。 （请参阅此处。）


• 您使用的是本地构建的Python版本，并且因为它是本地构建的，它使用 /usr/local/lib/python2.7 而不是 /usr/lib/python2.7 ，并且因为它没有Debian / Ubuntu自定义，所以它不会检查使用 dist-packages 。

• You used apt-get install python-paramiko to install Ubuntu's official Paramiko package to /usr/lib/python2.7/dist-packages.
• You used (I assume) Ubuntu's version of pip, which installs to /usr/local/lib/python2.7/dist-packages. (See here.)
• You used a locally built version of Python, and because it's locally built, it uses /usr/local/lib/python2.7 instead of /usr/lib/python2.7, and because it doesn't have Debian/Ubuntu customizations, it doesn't check use dist-packages.

解决方案：您应该能够将 /usr/local/lib/python2.7/dist-packages 添加到您的 / usr / local / bin / python 的 sys.path ，但是因为你使用的是Ubuntu，所以最容易让Ubuntu为你做的工作：

Solution: You should be able to add /usr/local/lib/python2.7/dist-packages to your /usr/local/bin/python's sys.path, but since you're using Ubuntu, it's easiest to let Ubuntu do the work for you:

• 使用/ usr / bin / python而不是本地版本。


• 尽可能使用Ubuntu的软件包（即使用 apt-get 而不是 pip ）。


• 其余使用virtualenv（以便在Ubuntu打包和个人安装的模块之间保持清晰的分离）。

• Use /usr/bin/python instead of a local version.
• Use Ubuntu's packages wherever possible (i.e., use apt-get instead of pip).
• Use virtualenv for the rest (to keep a clean separation between Ubuntu-packaged and personally installed modules).

我会这么做的r卸载本地版本的Python并删除 /usr/local/lib/python2.7 ，以确保不会发生进一步的不匹配。如果您不想那么激烈，那么您可以在 / usr / local / bin之前编辑$ PATH以放入 / usr / bin 默认情况下运行Python的系统版本。

I'd go so far as to uninstall the local version of Python and delete /usr/local/lib/python2.7, to ensure that no further mismatches occur. If you don't want to be that drastic, then you can edit your $PATH to put /usr/bin before /usr/local/bin to run the system version of Python by default.
