【问题描述】：

这是我第一次在 stackoverflow 上提问。

几天前，我一直在尝试在我的 cpanel 服务器上设置一个 python 应用程序。这是关于我一直在做的一个 django 项目。所以我想使用 pip 工具安装 mysqlclient。

cPanel, cloudlinux操作系统，阿帕奇最新版本，安装了 python 和 ruby 选择器

我已经通过从 python3.7 切换到 3.6 绕过了这个问题！但我仍然想知道为什么我使用 python3.7 会出现这些错误？

pip 安装 mysqlclient：

    version node not found for symbol SSLeay@OPENSSL_1.0.1
    /usr/bin/ld: failed to set dynamic section sizes: Bad value
    collect2: error: ld returned 1 exit status
    error: command 'gcc' failed with exit status 1

pip install mysqlclient 输出：

【解决方案1】：

如果你使用 cpanel

请检查并允许 gcc / 编译器

登录WHM
安全中心
编译器访问

允许特定用户并启用编译器

如果你启用了编译器，请重启virtualenv并再次尝试使用命令安装

pip 安装 mysqlclient

如果 pip 有问题，请使用命令升级 pip：pip install --upgrade pip
