python - 导入错误 : cannot import name HTTPSHandler

Question

刚刚安装了 pip，但我无法导入它。操作系统是 RedHat 企业版，我还安装了最新的 openssl(从源代码编译)。

我知道我必须以与 python 一起工作的方式配置我的 openssl(根据 this )。这是我在编译之前配置 openssl 的方式:

# openssl-1.0.2g 
./config --prefix=XXX/local \
        --openssldir=XXX/local/etc/ssl \
        --libdir=lib \
        shared \
        zlib-dynamic \
        -LXXX/local/lib \
        -IXXX/local/include 

Python版本为2.7

我正在使用 Centos 并面临这个问题。

最好的解决方法是:

yum install openssl openssl-devel -y 
yum install krb5-devel -y

尝试以下两个选项之一:

export LDFLAGS=-L/usr/local/opt/openssl/lib 
export CPPFLAGS=-I/usr/local/opt/openssl/include

  OR

重新编译
