如何在Ubuntu上安装M2Crypto？

Question

我正在尝试在Ubuntu 10.04 LTS上构建和安装M2Crypto。我下载并解压了M2Crypto-0.20.2.tar，然后在M2Crypto-0.20.2这个文件夹里运行了 python setup.py build。结果出现了错误，因为我没有安装swig。于是我执行了 sudo apt-get install swig 来安装它。之后我又试了一次 python setup.py build，结果又出现了错误：

...等等。

有没有人成功做到这一点？

更新：我改了标题，因为我之前没想到M2Crypto会是一个预先构建好的Ubuntu软件包。

Answer 1

可能有人会遇到与openssl相关的错误，可以试试这个：

sudo apt-get install openssl
sudo apt-get install libssl-dev

Answer 2

你有没有安装python2.6-dev这个软件包？这个软件包里包含了你缺少的Python.h文件。

Answer 3

你可能需要安装Python开发包：

sudo apt-get install python-dev

更好的办法是，别自己去编译m2crypto。它已经作为一个完全支持的包在Ubuntu的仓库里了。这样，你就可以通过和其他Ubuntu系统一样的方式，自动更新它：

sudo apt-get install python-m2crypto
