Question

大家。首先，我的操作系统是 RHEL7.2，我使用的是python3.5。
我想用pip来做我想要的东西。然后，在我成功安装pip3后，我想用pip来安装一些东西，但它显示我 ImportError：无法导入名称'HTTPSHandler'。并且我按照网站上的解决方案yum install openssl-devel，但它显示错误：

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

我无法独立解决。希望你能帮助我。谢谢。

PS：整个错误信息是：

Answer 1

首先检查一下安装openssl-develop

sudo apt-get install libssl-dev

或

yum install openssl-dev -y

尝试其他方式重新安装pip3，以Ubuntu为例

sudo apt-get install python3-setuptools
sudo easy_install3 pip

使用setuptools安装pip可以解决依赖问题。

在RHEL

上试用

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

Answer 2

我解决了我的问题。

我有很多存储库，一个存储库中的一些数据与另一个存储库冲突。所以我按照第一个建议：我reinstall krb5-server，然后我yum install openssl-devel，它运作良好。
解决第一个问题后，我使用了pip失败了，我遵循了第二个建议：我重新编译了python3.5，问题解决了。

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