OS X上的Python 2.7：TypeError：'frozenset'对象在每个命令

Question

我在使用Python的每个命令上都有这个错误：

➜  /tmp sudo easy_install pip
Traceback (most recent call last):

TypeError: 'frozenset' object is not callable

我该怎么办？

Answer 1

我也有这个问题，但我也需要安装hashlib包（在Debian上）。

我找到的最佳解决方案（最好用easy_install安装hashlib）来自这里： https://askubuntu.com/questions/770262/python-hashlib-fails-to-install-pip

它是：

“快速而又脏的修复方法是删除/usr/lib/python2.7/lib-dynload/_hashlib.x86_64-linux-gnu.so文件”

在此之后，可以使用pip安装hashlib！

Answer 2

删除这个包有帮助我：

sudo rm -rf /Library/Python/2.7/site-packages/hashlib-20081119-py2.7-macosx-10.11-intel.egg
