在osx上安装pycrypto的问题

Question

我正在尝试将Django项目安装到我的OSX机器上,这需要PyCrypto.我收到以下错误:

running install

running build_py
running build_ext
running build_configure
checking for gcc... no
checking for cc... no

configure: error: in `/Users/home/Documents/tmp/dlitz-pycrypto-d2170a4':

Answer 1

configure: error: no acceptable C compiler found in $PATH

此错误不言自明.获取C编译器.

XCode应该工作.

Answer 2

如果你在Lion上使用Xcode 4.x,你需要跳过一些额外的箍来编译和安装:

1)在Xcode中,转到Preferences> Downloads,然后单击"Command Line Tools"旁边的"Install"按钮,安装Python所需的编译器.

2)在我的情况下,我必须创建一个从gcc到gcc-4.2的临时符号链接,以使pycrypto编译器闭嘴.在终端窗口中,su获取root访问权限:

a)确保安装了gcc:

# which gcc
/usr/bin/gcc

b)创建符号链接:

# ln -s /usr/bin/gcc /usr/bin/gcc-4.2

3)cd进入你的pycrypto目录并构建并安装pycrpto:

# cd ~/Downloads/pycrypto-2.5 (或你的版本)
# python setup.py build
# python setup.py install

4)删除您之前创建的符号链接:

# rm /usr/bin/gcc-4.2

如果你的过程像我的一样,你应该在Lion上安装一个功能正常的pycrypto.
