我在Mac OSX 10.8(Mountain Lion)上,刚安装了Python 3.2.3。
使用该版本的python从虚拟环境安装pycrypto时:
$ virtualenv --no-site-packages -p /usr/local/bin/python3.2-32 venv
$ source venv/bin/activate
$ pip install pycrypto
我收到错误:
gcc-4.2 not found, using clang instead
building 'Crypto.Hash._MD2' extension
warning: GMP or MPIR library not found; Not building Crypto.PublicKey._fastmath.
Compiling with an SDK that doesn't seem to exist: /Developer/SDKs/MacOSX10.6.sdk
Please check your Xcode installation

尝试安装加密时会发生类似的事情。
As of version 2.4, Pycrypto says it supports python 3.
我在xcode开发者文件夹中添加了一个符号链接:
$ sudo ln -s /Applications/Xcode.app/Contents/Developer/Platforms/MacOSX.platform/Developer /Developer
但该文件夹中存在的所有内容都是MacOSX10.7.sdk MacOSX10.8.sdk(不是上面需要的MacOSX10.6.sdk)。
我在系统中遗漏了什么?如何告诉它使用其他SDK?
答案 0 :(得分:4)
通过执行以下操作来实现它:
与上面的评论一样,确保安装了命令行工具,这也安装了系统标题:
启动Xcode,打开Xcode - &gt;首选项...并转到“下载”标签。在“组件”下,确保已安装命令行工具;这也将在系统文件夹中安装系统头文件。
按照this answer中的说明,创建指向开发者文件夹的符号链接:
sudo ln -s /Applications/Xcode.app/Contents/Developer/Platforms/MacOSX.platform/Developer /Developer
但是,仍然会出现错误消息:
Compiling with an SDK that doesn't seem to exist: /Developer/SDKs/MacOSX10.6.sdk
这与issue that Python 3.2 assumes you are using Mac OSX 10.6
有关我修复了这个问题,这是通过伪装OSX 10.6环境创建一个从它到OSX 10.8环境的符号链接:
sudo ln -s /Developer/SDKs/MacOSX10.8.sdk MacOSX10.6.sdk
包已成功安装。
