1. 描述
搞了个腾讯云的服务器，闲在手上没事准备当个测试机用用，写写代码什么的。然后按照之前写的文章安装了python2.7，安装的中途出现了一个错误：

其实错误一眼就能看出是缺少了zlib库，然后使用yum install zlib zlib-devel安装了库之后python setup.py install 发现还是一样报错。
2. 解决方法
装好zlib相关库之后把把python重新安装一遍，进入到源码目录：

yum install zlib zlib-devel
make && make install

2. 解决方法
缺少distribute模块，使用pip安装也装不上，需要在官网下载源码安装。

wget https://pypi.python.org/packages/source/d/distribute/distribute-0.6.10.tar.gz
tar -zxvf distribute-0.6.10.tar.gz
cd distribute-0.6.10
python setup.py install

pip is configured with locations that require TLS/SSL, however the ssl module in Python is not available.
Collecting shadowsocks
Could not fetch URL https://pypi.python.org/simple/shadowsocks/: There was a problem confirming the ssl certificate: Can"t connect to HTTPS URL because the SSL module is not available. - skipping
Could not find a version that satisfies the requirement shadowsocks (from versions: )
No matching distribution found for shadowsocks

2. 解决方法
系统缺少openssl-devel包，使用yum install openssl-devel安装。
然后重新安装python：进入python源码目录，make && make install，解决。
