Python2.7中六个模块的问题

Question

当我尝试使用El Capitan 10.11.6在我的Mac上安装twilio时，问题就出现了。

我收到了这个错误：

    OSError: [Errno 1] Operation not permitted: '/tmp/pip-EmsRHo-uninstall/System/Library/Frameworks/Python.framework/Versions/2.7/Extras/lib/python/pyOpenSSL-0.13.1-py2.7.egg-info'

研究通知我应该运行pip install --ignore-installed six ，这显示以下错误：

例外：

Traceback (most recent call last):
  File "/Library/Python/2.7/site-packages/pip-9.0.1-py2.7.egg/pip/basecommand.py", line 215, in main
    status = self.run(options, args)
  File "/Library/Python/2.7/site-packages/pip-9.0.1-py2.7.egg/pip/commands/install.py", line 342, in run
    prefix=options.prefix_path,
  File "/Library/Python/2.7/site-packages/pip-9.0.1-py2.7.egg/pip/req/req_set.py", line 784, in install
    **kwargs
  File "/Library/Python/2.7/site-packages/pip-9.0.1-py2.7.egg/pip/req/req_install.py", line 851, in install
    self.move_wheel_files(self.source_dir, root=root, prefix=prefix)
  File "/Library/Python/2.7/site-packages/pip-9.0.1-py2.7.egg/pip/req/req_install.py", line 1064, in move_wheel_files
    isolated=self.isolated,
  File "/Library/Python/2.7/site-packages/pip-9.0.1-py2.7.egg/pip/wheel.py", line 345, in move_wheel_files
    clobber(source, lib_dir, True)
  File "/Library/Python/2.7/site-packages/pip-9.0.1-py2.7.egg/pip/wheel.py", line 323, in clobber
    shutil.copyfile(srcfile, destfile)
  File "/System/Library/Frameworks/Python.framework/Versions/2.7/lib/python2.7/shutil.py", line 83, in copyfile
    with open(dst, 'wb') as fdst:
IOError: [Errno 13] Permission denied: '/Library/Python/2.7/site-packages/six.py'

进一步的研究告诉我运行brew install python

我再次尝试运行pip install twilio

新错误：

Traceback (most recent call last):
  File "/usr/local/bin/pip", line 6, in <module>
    from pkg_resources import load_entry_point
  File "/Users/rdacso/Library/Python/2.7/lib/python/site-packages/pkg_resources/__init__.py", line 48, in <module>
    import six
ImportError: No module named six

我试图pip install six ，但继续得到这个错误：

Traceback (most recent call last):
  File "/usr/local/bin/pip", line 6, in <module>
    from pkg_resources import load_entry_point
  File "/Users/rdacso/Library/Python/2.7/lib/python/site-packages/pkg_resources/__init__.py", line 48, in <module>
    import six
ImportError: No module named six

由于没有模块六，所有东西都显得很笨拙。 我无法安装或卸载六个。 甚至pip freeze也显示ImportError: No module named six 。

Answer 1

当我运行brew install python我设法安装了第二个python库。 这导致了决斗蟒蛇。

我运行brew uninstall python ，使用easy_install pip重新安装了pip，这让我有能力再次pip install six 。

完成后，我能够使用easy_install twilio而不是pip install twilio 。
