【问题描述】：

在我的 Mac 终端窗口中出现以下错误。

$ pip --version
pip 6.1.1 from /Library/Python/2.7/site-packages (python 2.7)

Python 版本是 2.7.10

尝试使用 brew 安装 credstash 时，出现以下错误。

$ `which python` --version && brew update && brew install credstash
Python 2.7.10
Already up-to-date.
Error: No available formula with the name "credstash" 
==> Searching for similarly named formulae...
Error: No similarly named formulae found.
==> Searching taps...
Error: No formulae found in taps.

当我尝试使用 brew 安装 pip3 时遇到了类似的错误。

尝试从 pip 安装 credstash，但也出错了。

You are using pip version 6.1.1, however version 9.0.1 is available.
You should consider upgrading via the 'pip install --upgrade pip' command.

    DEPRECATION: Uninstalling a distutils installed project (six) has been deprecated and will be removed in a future version. This is due to the fact that uninstalling a distutils project will only partially uninstall the project.
    Uninstalling six-1.4.1:

如果我在上述命令中没有使用 sudo，则会收到以下异常错误：

OSError: [Errno 13] Permission denied: '/Library/Python/2.7/site-packages/concurrent'

要获取最新的 pip，因为 pip 是通过 macOS 上的 python 提供的，如果我尝试使用 brew 安装 python，我会得到以下信息，我会深入探讨如何首先删除 Xcode：

$ brew install python
Error: Your Xcode (5.0.2) is too outdated.
Please update to Xcode 8.2 (or delete it).
Xcode can be updated from the App Store.

$ pip --version
pip 6.1.1 from /Library/Python/2.7/site-packages (python 2.7)

因为我认为我有一个较旧的 pip 版本，所以我下载了这个文件：

$ wget https://bootstrap.pypa.io/get-pip.py && sudo python get-pip.py

成功安装了更新版本的 pip。现在显示：

$ pip --version
pip 9.0.1 from /Library/Python/2.7/site-packages (python 2.7)

尝试执行 pip install credstash 但仍然出现相同的错误（使用或不使用 sudo）。

标签： macos pip homebrew credstash

【解决方案1】：

如果您尝试安装到系统 Python，那么您需要 sudo。如果您只想玩玩，请考虑创建一个 virtualenv 并安装在那里。 http://docs.python-guide.org/en/latest/dev/virtualenvs/

【讨论】：

太棒了，我从来没有机会玩 virtualenv 但现在我一定会试试的。
这对我有用 sudo -H pip install credstash 在 OSX 上

【解决方案2】：

我尝试了以下方法来安装 credstash。

从这里下载 Python3 Mac 二进制文件。

https://www.python.org/ftp/python/3.5.2/python-3.5.2-macosx10.6.pkg

安装了.pkg文件的GUI方式。

在 Mac 中打开了一个终端窗口。
