为什么我无法安装greenlet（一个基本的Python包）？

Question

我从这个网址下载的压缩包并解压了：http://pypi.python.org/pypi/greenlet#downloads。
（我在我的虚拟环境中操作的。我也进行了相关设置，所以我没有使用sudo权限。）

Answer 1

你没有安装 python-dev，所以找不到 Python.h 这个头文件。

Answer 2

在Ubuntu系统上，你需要安装一个叫做python-dev的软件包。这个软件包里面包含了Python.h这个头文件：

% dpkg -S /usr/include/python2.6/Python.h
python2.6-dev: /usr/include/python2.6/Python.h
