Question

我通过Macports安装了python2.7和python3.5。我试图让neovim启动并运行，为此我跑了

$ sudo pip2 install neovim
$ sudo pip-3.5 install neovim

将软件包安装到/opt/local/Library/Frameworks/Python.framework/Versions/的不同子目录中。现在运行Python 3.5时，import neovim尝试加载2.7包（失败），正如我从堆栈跟踪中看到的那样。

完整的错误是：

$ python3.5 -c "import neovim"
Traceback (most recent call last):

为了让Python 2.7和3在我的系统上和平共存，我该怎么做？

我最近也遇到了这个问题，但与PYTHONPATH无关，我的机器上没有设置{em> 。在我的情况下，Python和pip是通过MacPorts安装的。清理，自我更新MacPorts，然后将pip更新为最新版本，然后运行以下内容解决了问题：

port select --set pip pip35

为什么python35 import尝试加载python27包？
