在macOS上安装pip Sierra

Question

我一直试图通过brew在macOS sierra上安装pip，但每次完成时都没有在/usr/local/Cellar/python/2.7.13/bin中安装二进制文件。

我已经试过：

MacBook-Pro ➜ brew reinstall python 

则：

MacBook-Pro ➜ ~ which pip 
pip not found 

我发现的路径，蟒蛇，这是/usr/local/Cellar/python/2.7.13/bin但没有二进制的点子出现。

我也试过easy_install方法：

MacBook-Pro ➜ sudo easy_install pip 
Traceback (most recent call last): 
    File "/usr/bin/easy_install-2.7", line 11, in <module> 
    load_entry_point('setuptools==18.5', 'console_scripts', 'easy_install')() 
    File "/Library/Python/2.7/site-packages/pkg_resources.py", line 352, in load_entry_point 
    return get_distribution(dist).load_entry_point(group, name) 
    File "/Library/Python/2.7/site-packages/pkg_resources.py", line 2307, in load_entry_point 
    return ep.load() 
    File "/Library/Python/2.7/site-packages/pkg_resources.py", line 2021, in load 
    entry = __import__(self.module_name, globals(),globals(), ['__name__']) 
    File "/System/Library/Frameworks/Python.framework/Versions/2.7/Extras/lib/python/setuptools/__init__.py", line 12, in <module> 
    from setuptools.extension import Extension 
    File "/System/Library/Frameworks/Python.framework/Versions/2.7/Extras/lib/python/setuptools/extension.py", line 8, in <module> 
    from .dist import _get_unpatched 
    File "/System/Library/Frameworks/Python.framework/Versions/2.7/Extras/lib/python/setuptools/dist.py", line 21, in <module> 
    packaging = pkg_resources.packaging 
AttributeError: 'module' object has no attribute 'packaging' 

UPDATE：

当我运行brew postinstall python我收到以下错误：

MacBook-Pro ➜ ~ brew postinstall python

一定出事了你酿造安装。

最新的macOS版本。

~/ brew reinstall python

==> Caveats 
Pip and setuptools have been installed. To update them 
    pip install --upgrade pip setuptools 

You can install Python packages with 
    pip install <package> 

They will install into the site-package directory 
    /usr/local/lib/python2.7/site-packages 

See: https://github.com/Homebrew/brew/blob/master/docs/Homebrew-and-Python.md 

.app bundles were installed. 
Run `brew linkapps python` to symlink these to /Applications. 
==> Summary 
    /usr/local/Cellar/python/2.7.13: 3,526 files, 48M 

它绝对存在。

~/ ls -l $(which pip) 
lrwxr-xr-x 1 cricket admin 31 Dec 19 19:43 /usr/local/bin/pip -> ../Cellar/python/2.7.13/bin/pip 

Answer 2

错误消息对你答案......

删除/Users/justin/.venvburrito/lib/python/distribute-0.6.35-py2.7.egg/和运行brew reinstall python。 setuptools是错误的版本。

Answer 3

你只需要安装pip这是不是自动安装在macOS Sierra。

运行sudo easy_install pip

Answer 4

我有这个问题，我发现这是解决方案。 BTW pip不是通过brew安装的。它带有python和python virtualenvs。

如果您输入which python而没有brew install python您将获得/usr/bin/python中的位置。这是我们不想开发的系统python。

所以我采取了以下步骤。 1）brew install python 2）export PATH="/usr/local/opt/python/libexec/bin:$PATH"地方，在你~/.bash_profile 3）source ~/.bash_profile在终端 4）式which python和应已经改变了位置/usr/local/opt/python/libexec/bin/python。

这将允许您正常点击安装并使用brew版本的python。

现在摆在高塞拉利昂Python中位于/usr/local/bin但出于某种原因，如果你把你的路径/usr/local/bin它会自动指向回/usr/bin，所以这是唯一的解决方案，我已经能够拿出。

Python3没有这个问题，如果你brew install python3和类型which python3你会发现它位于/usr/local/bin/python3。

Answer 5

这是值得的，在升级到高级雪利山后，我发现我的机器几乎无法用于开发，甚至崩溃了很多次。

关于蟒蛇，我有站点包文件夹内的配股，因此重装没有发挥出来：

$ brew reinstall python

因此，要解决这个问题，我完全清除站点包：

$ sudo rm -rf /usr/local/lib/python2.7/site-packages 

有了这个，重新安装python2，又具有工作PIP2，工作就像一个魅力：

$ brew reinstall python 

$ which pip2 
/usr/local/bin/pip2 
$ which python2 
/usr/local/bin/python2 

$ which pip 
pip not found 
$ which python 
/usr/bin/python 

希望有所帮助。
