"pip install SQLAlchemy"导致"致命错误:Python.h:没有这样的文件或目录"

Question

调用

pip install SQLAlchemy

我收到一个错误:

lib/sqlalchemy/cextension/processors.c:10:20: fatal error: Python.h: No such file or directory

据我所知,我有正确的Python版本(2.7.3)和操作系统(Ubuntu 12.04)(见下文).我做错了吗？

安装确实有效

pip install --global-option='--without-cextensions' SQLAlchemy"

但我想要C扩展.

您需要python-dev为您的Python版本安装(或类似名称)包.它包括编译C扩展所需的所有头文件.(遗憾的是)这些文件不包含在默认python包中.

对于Ubuntu,命令是

sudo apt-get install python-dev

要么

sudo apt-get install python3-dev

取决于您使用的版本.
