'；sudo pip安装-e.&x27；更新/usr/local/lib下的easy-install.pth，python可以'；不进口

我在MacOs Sierra上

我遇到了一个问题，使用

sudo pip install-e

安装我自己的包会导致

/usr/local/lib/python2.7/site packages/easy install.pth

被更新为指向包，但在python启动时显然找不到

这闻起来像是与我在一段时间前将

/usr/local/bin/python

链接到

/usr/bin/python

以解决一些我再也记不起的其他版本冲突类型问题有关

有没有一种明智的方法来解决这个问题，比如在

site.py

中编辑一些东西

我不确定这里还需要什么额外的细节。这里有大量来自系统的相关命令输出

pip安装似乎成功了：

~$ cd workspace/mypackage
mypackage$ sudo -H pip install -e .

安装更新的

tmp$ sudo find /usr -name easy-install.pth

在虚拟电视中，所有这些都是正常的：

(testpip) mypackage$ cd /tmp
(testpip) tmp$ python -c 'import mypackage; print mypackage.__file__'
/Users/me/workspace/mypackage/mypackage/__init__.pyc

…或在执行不可编辑的安装时：

$ /usr/local/bin/python2.7-cellar  -c 'import mypackage; print mypackage.__file__'
/usr/local/lib/python2.7/site-packages/mypackage/__init__.pyc

在上一个示例中，输出显示成功安装了argus-tools-1.0.0。但是你不是想安装的

mypackage

？同样，在virtualenv中一切都很好，那么为什么不坚持这个解决方案呢？您可能应该在一开始就使用virtualenv，然后再乱搞到其他python版本的符号链接。您可能想看看：哎呀，argus工具来自原始案例，我在确定特定的包不是问题所在后对其进行了泛化，但错过了那个。固定的。是的，坚持使用virtualenv可以解决这个问题，但现在我在这里，我想了解引擎盖下发生了什么。：）此外，这可能最终部署在virtualenv不可用的环境中（尽管MacOs上不会出现这种情况，所以我相信这个问题也不会出现）
