尝试在Python 3.6.0上使用pip3安装mysqlclient

Collecting mysqlclient
  Using cached mysqlclient-1.3.10.tar.gz
    Complete output from command python setup.py egg_info:

已经做了

brew install mysql-connector-c

但仍然得到这个错误

Answer 1

这对我有用:

1. brew install mysql-connector-c

2. 编辑mysql_config(找到它:which mysql_config)

在mysql_config中更正此问题:

# Create options 
libs="-L$pkglibdir"
libs="$libs -l "

它应该是:

# Create options 
libs="-L$pkglibdir"
libs="$libs -lmysqlclient -lssl -lcrypto"

4. brew info openssl
5. 最后 pip3 install mysqlclient

Answer 2

我先解决了这个安装libmysqlclient-dev的问题:

sudo apt-get install libmysqlclient-dev

希望对你有效.

Answer 3

经过大量的故障排除后,我发现它brew install mysql-connector-c只是不起作用.

问题源于系统无法识别mysql_config安装(这mysql-connector-c基本上是什么).Homebrew的方法(打开参数)安装mysql-connector-c在其中/Cellar/并创建一个符号链接到该/usr/local/bin/目录似乎导致问题,因为Python试图遵循符号链接.

为解决此问题,我执行了以下操作:

1. brew uninstall mysql-connector-c
2. 从Oracle的MySQL站点 下载/安装MacOS X MySQL Connector/C.
   • 注意:只需下载.dmg,这里不需要复杂......
3. 重新启动MacOS终端(或iTerm2)以获得良好的衡量标准

4. which mysql_config

   • 你应该看到正确的道路 /usr/local/bin/mysql/bin/mysql_config

5. 激活virtualenv(如果适用)

6. pip install mysqlclient

可能还有其他方法仍然使用Homebrew,但这是我找到的最直接的解决方案.

请注意,mysqlclientGitHub README.md还指出需要Python3的C-developer头文件.我认为那mysql-connector-c包括那些; 但是,如果您遇到更多问题,您也可以安装Xcode Developer CI Tools.

xcode-select --install

它们包括C编译器和Apple的其他开发人员实用程序.在这里阅读更多.
