无法安装在virtualenv中psycopg2“错误：STDARG.H：没有这样的文件或目录”

Question

注意：在使用时的easy_install安装的其他方式也会发生同样的错误......

我面对几乎与I'm trying to install psycopg2 onto Mac OS 10.6.3; it claims it can't find "stdarg.h" but I can see it's there; what should I do?完全相同的问题，除了我在OSX Lion（10.7）和我在Python v2.7上。

它也似乎与Can't install psycopg2 with pip in virtualenv on Mac OS X 10.7有关，但我收到了不同的错误消息。

我提出了一个新问题，因为解决方案适用于OSX 10.6（例如http://mail.python.org/pipermail/pythonmac-sig/2009-September/021617.html）不适用于我。

我想在Heroku上执行Django的教程（https://devcenter.heroku.com/articles/django）， ，我遇到了一个尝试安装psycopg2的错误。这里的痕迹：

我不知道它为什么找不到stdarg.h！我在网上查了很多答案，都没有用。

Answer 1

它看起来像你有一个破碎的构建环境。 stdarg.h是核心gcc头文件的一部分。在我的（Fedora 16 Linux）系统上，stdarg.h位于/usr/lib/gcc/x86_64-redhat-linux/4.6.2/include/stdarg.h，是gcc包的一部分。

在苹果平台上，我希望它随Xcode一起提供。猜测，你有多个编译器/工具链安装，他们的包含路径越来越混乱。我建议彻底卸载XCode及其所有朋友，删除相关目录以摆脱落后者，然后重新安装。

Answer 2

这可能是您的Xcode安装不完整。下面的后帮我得到它的工作：

必须安装“命令行工具”的Xcode的（按照上面SO回答方向），然后我能够点子用的virtualenv安装。
