今天玩linux deploy 安装了一下debian系统,安装python2.7环境,import ssl却出现错误！

网上搜了一下, 大概是python编译生成的时候,没有编译好,从网上找到如下解决方案，记录一下。
安装openssl
sudo apt-get install openssl
这个是安装ssl的命令，大部分系统中会自带安装，如果提示已经安装成功可以直接忽略，后面那个才是较为重要的
安装 libssl-dev
sudo apt-get install libssl-dev

这个是安装libssl-dev库，如果是centos（redhat系）的系统，可以尝试sudo yum install libssl-devel这个命令 之后进入python的源码包目录，如果不知道自己安装包目录的童鞋可以看我另外一篇文章（翻到最下面有个引用） 进入python的源码包后，输入以下指令
sudo make clean
./configure
sudo make test
sudo make && sudo make install
以上重新打包编译安装的代码，可以解决大部分童鞋的问题。
debian，pythoImportError
