Question

我正在运行ubuntu 16.04并且有一些使用python 3.6功能的python代码。我已经能够使用python3.6和pip3.6安装一些库（scipy）。但是有一些库（pycurl）使用pip install不起作用：

$sudo python3.6 -m pip  install pycurl
Requirement already satisfied: pycurl in /usr/lib/python3/dist-packages (7.43.0)

这不允许我在python3.6环境中导入pycurl。如果我改为使用升级，我会收到有关pycurl是distutils安装包的错误。

如何为我的python3.6安装访问pycurl？

$ sudo python3.6 -m pip  install --upgrade pycurl

Cannot uninstall 'pycurl'. It is a distutils installed project and thus we cannot accurately determine which files belong to it which would lead to only a partial uninstall.

所以问题似乎是它安装在/usr/lib/python3/dist-packages中。通过运行sudo pip3 install --upgrade pycurl它已移至：/usr/local/lib/python3.5/dist-packages，然后sudo python3.6 -m pip install pycurl可以安装。

我不知道为什么这是一个问题，但它解决了这个问题。
