这个错误提示是在编译安装 mysqlclient 时产生的，提示找不到 zlib 库。你可以尝试以下两种方法解决该问题：

1. 安装 zlib 库

如果你已经安装了 zlib，但是还是出现了该错误，可以尝试重新安装一遍 zlib 库。如果还是不行，可以尝试安装 zlib-devel 库。

2. 指定 zlib 库位置

如果你已经安装了 zlib，但是编译时还是找不到该库，可以尝试手动指定 zlib 库的位置。在编译 mysqlclient 时加上以下参数：

LDFLAGS=-L/path/to/zlib/lib CPPFLAGS=-I/path/to/zlib/include pip install mysqlclient

其中 `/path/to/zlib/lib` 和 `/path/to/zlib/include` 分别为 zlib 库和头文件所在的目录。
