ImportError：無法導入名稱HTTPSHandler

Question

剛剛安裝了pip，但我無法導入它。 操作系統是RedHat企業，我也安裝了最新的openssl（從源代碼編譯）。

我知道我必須以與python一起工作的方式配置我的openssl（根據這個 ）。 這是我在編譯之前配置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版本是2.7

我正在使用Centos並面臨這個問題。

最好的解決方法是：

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

嘗試以下兩種選擇之一：

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

  OR

重新編譯它
