问题描述

系统：MacOS 10.14.3

蟒蛇：3.7.3

mysql: 5.7.25 ( brewhome 安装: brew install mysql@5.7 )

当我使用pip install myclient ，我得到了以下错误跟踪：

根据错误消息，我尝试运行clang -v并获取以下信息：

Apple LLVM version 10.0.1 (clang-1001.0.46.4)
Target: x86_64-apple-darwin18.2.0
Thread model: posix
InstalledDir: /Library/Developer/CommandLineTools/usr/bin

我看到有很多关于堆栈溢出的问题，并观看了它们，但它们不能解决我的问题，我尝试运行xcode-select install ，并安装另一个版本的 mysqlclient，都失败了。

我也谷歌它但也不适合我。

现在我真的不知道发生了什么以及如何解决它，

2 个解决方案

解决方案1
 2  2019-11-19 11:04:24

LDFLAGS=-L/usr/local/opt/openssl/lib pip install mysqlclient

因为 openssl 是依赖项，并且此语句将路径设置为所需的库。 （只有在已经安装了 openssl 时才有效。）

问题在这里：

现在-lssl是什么或者为什么这是一个我无法弄清楚的问题，但我认为您需要安装lssl库： ld: library not found for -lssl 。
