网友推荐解决办法：

1.设置 shell 环境变量 

?


1

# export GIT_SSL_NO_VERIFY=true

2.设置 git 的环境变量 

?


1

# git config --global http.sslVerify false

采用第二种方法执行结果:

[root@Betty setuptools-0.9.1]#

      安装 setuptools-0.9.1 过程中报缺少 zlib 库。原因应该是，我在安装 Python2.7 的时候尚未安装 zlib 和 zlib-devel 。后续安装了这两个库，但此时 Python 中没有将其编译进去。所以需要重新编译 Python 。

若未安装可以使用如下命令安装：

?


1

# yum install zlib zlib-devel

重新安装 setuptools-0.9.1 成功。

网友说：因为 Python 编译安装时缺少 SSL 相关的库导致，所以需要安装 openssl-devel 后重新编译安装 Python 。 

?


1

[root@Betty ~]# yum -y install openssl-devel

安装成功后，重新编译安装 Python ，在执行 pip 命令安装 pika 成功。
