我尝试在最后几个小时在我的 mac 10.8 上安装 grequests。

当pip install我得到：

$ pip install grequests
Requirement already satisfied (use --upgrade to upgrade): grequests in /Library/Frameworks/Python.framework/Versions/3.2/lib/python3.2/site-packages
Downloading/unpacking gevent (from grequests)

    Complete output from command python setup.py egg_info:

                           ^

----------------------------------------

这似乎是一个gevent安装问题，因为我在使用时遇到了同样的错误：

 pip install gevent #same with pip-3.2

所以我去看看如何手动安装 gevent 。我将其视为先决条件greenlet。

我pip install它，但我得到：

lipo: can't figure out the architecture type of: /var/folders/hx/_6mzcrld6777n9mfkx7g9dmc0000gp/T//ccRlrUpW.out
error: Setup script exited with error: command 'gcc-4.2' failed with exit status 1

但是我有 GCC：

$ gcc
i686-apple-darwin11-llvm-gcc-4.2: no input files

也许我把 GCC 搞砸了。

还：

$ sudo port install py-greenlet
Error: Port py-greenlet not found

所以，这就是我走了多远。有任何想法吗？

更新：

我通过简单地编译 tarball 来解决 GCC 错误python setup.py build install。虽然我安装了 Cython，但在尝试安装gevent构建的 tarball 时出现错误。

好的，这就是我所做的一切。我清除了 /usr/local/bin 中的 GCC。现在它在 /usr/bin 中。我使用了 ggc 安装程序包，我不知道这是否有帮助，但我做到了。

我更新到 2.7.5（我有 2.7.2）和pip install cython. 我被安装了。与gevent和相同grequest。并做了。

但是gevent，也许cython似乎在 python 3.3 中出现了问题。
