问错误：mysqlclient构建wheel失败

EN

我无法'pip install mysqlclient'，并且每次尝试都会返回错误：'ERROR：mysqlclient构建轮失败'。对于上下文，我正在运行macOS Mojave 10.14.5。本文的其余部分假设已经下载了'python == 3.6'和'virtualenv'。此外，已经安装了x-code命令行工具（不是我认为这很重要）。

这个步骤是（从命令行）：

1. 'virtualenv~ / venv'
   • 输出：

   使用基本前缀'/usr/local/Cellar/python/3.6.5_1/Frameworks/Python.framework/Versions/3.6'/Users/usr1/venv/bin/python3.6中的新python可执行文件还在/ Users /中创建可执行文件usr1 / venv / bin / python安装setuptools，pip，wheel ......完成。“

2. 'source~ / venv / bin / activate'
3. 'pip install mysqlclient'

到目前为止，我已经查看并尝试了一切：

1. mysqlclient的构建轮失败
2. “psycopg2构建轮失败” - MacOSX使用virtualenv和pip
3. mysql-python的构建轮失败 收集mysqlclient使用缓存的https://files.pythonhosted.org/packages/f4/f1/3bb6f64ca7a429729413e6556b7ba5976df06019a5245a43d36032f1061e/mysqlclient-1.4.2.post1.tar.gz 为收集的包构建轮子：mysqlclient构建mysqlclient轮子（setup.py）。 ..错误错误：从命令/Users/usr1/venv/bin/python3.6 -u -c'导入setuptools，tokenize完成输出; 文件 = ' “ ' ” '/私有的/ var /文件夹/ 2J / 1qt0_7q96lxbxl2w5kx8r1zr0000gn / T / PIP安装-4uobjq_4 /的mysqlclient / setup.py'“'”'; F = GETATTR（标记化，“'” '开放' “'”'，open（文件）; code = f.read（）。replace（'''''\ r \ n'“'''，'''''\ n''''''）; F。' “ ' 'EXEC''”'））” bdist_wheel -d /私人的/ var /文件夹/ 2J / 1qt0_7q96lxbxl2w5kx8r1zr0000gn / T / PIP轮ehvuw9uv --python标签CP36：ERROR：运行bdist_wheel运行构建运行build_py创建构建创建build / lib.macosx-10.13-x86_64-3.6创建build / lib.macosx-10.13-x86_64-3.6 / MySQLdb复制MySQLdb / init.py -

CONCLUSION: Ideally, I would like for 'pip' to simply install 'mysqlclient'. I would very much appreciate the help. Thanks in advance.
