python3.5 pip ImportError：无法导入名称“ HTTPSHandler”

Question

大家 首先，我的操作系统是RHEL7.2，我使用python3.5。
我想用pip来做我想做的事。然后，在成功安装pip3之后，我想用pip来做事，但它向我显示ImportError：无法导入名称“ HTTPSHandler” 。然后按照网站上的解决方案yum install openssl-devel ，但显示错误：

Transaction check error:
  file /usr/bin/sclient from install of krb5-devel-1.13.2-10.el7.x86_64 conflicts with file from package krb5-server-1.13.2-10.el7.x86_64
  file /usr/sbin/sserver from install of krb5-devel-1.13.2-10.el7.x86_64 conflicts with file from package krb5-server-1.13.2-10.el7.x86_64

我不能独立解决它。希望您能帮助我。谢谢。

PS：整个错误消息是：

Answer 1

首先检查Wheather安装openssl-develop

sudo apt-get install libssl-dev

要么

yum install openssl-dev -y 

尝试另一种方式重新安装pip3 ，例如Ubuntu

sudo apt-get install python3-setuptools
sudo easy_install3 pip

使用setuptools安装pip可能可以解决依赖性问题。

在RHEL上尝试

sudo yum install -y python35-setuptools
sudo easy_install-3.5 pip

Answer 2

我解决了我的问题。

1. 我有很多存储库，一个存储库中的某些数据与另一个存储库冲突。 因此，我遵循第一个建议： reinstall krb5-server ，然后yum install openssl-devel ，它运行良好。
2. 解决第一个问题后，我未成功使用pip并遵循第二个建议：我重新编译python3.5并解决了问题。
