安装MySQL-python报错'my_config.h' file not found终极解决方案
注意:如果你用的是python3.x,直接去看第四个问题
遇到的第一个问题
-
正常来说直接执行pip安装,就是可以的,但是MySQL-python偏偏比较独特
pip install MySQL-python
-
报错
_mysql.c:44:10: fatal error: 'my_config.h' file not found #include "my_config.h" ^~~~~~~~~~~~~ 1 error generated. error: command 'cc' failed with exit status 1
解决第一个问题
-
执行
brew install mysql-connector-c
brew install mysql-connector-c
-
如果这一步直接完成,那就可以继续
pip install MySQL-python
了,应该会成功 -
但是我在这一步执行失败了
遇到第二个问题
-
brew install mysql-connector-c
报错Error: Cannot install mysql-connector-c because conflicting formulae are installed. mysql: because both install MySQL client libraries Please `brew unlink mysql` before continuing.
解决第二个问题
- 按照报错的提示,执行
brew unlink mysql
- 没有发生什么意外,执行完毕,继续执行
brew install mysql-connector-c
- 'mysql-connector-c’安装成功
- 执行
brew link --overwrite mysql
,重新连接mysql(这一步我没有做) - 然后再执行
pip install MySQL-python
,如果成功了就搞定了 - 神奇的是,我在这一步又失败了
遇到的第三个问题
-
上面的步骤走完以后,执行
pip install MySQL-python
,报错Collecting mysql Downloading https://files.pythonhosted.org/packages/06/ef/c4efbf2a51fb46aba9be03a973638d9539c9ca10a5259b2cbb1a66133b2e/mysql-0.0.1.tar.gz Collecting MySQL-python (from mysql) Using cached https://files.pythonhosted.org/packages/a5/e9/51b544da85a36a68debe7a7091f068d802fc515a3a202652828c73453cad/MySQL-python-1.2.5.zip Complete output from command python setup.py egg_info: Traceback (most recent call last): File "<string>", line 1, in <module> File "/private/var/folders/zn/t8xxx4m149s9jqp1810ndrz80000gn/T/pip-install-oHMKPE/MySQL-python/setup.py", line 17, in <module> metadata, options = get_config() File "setup_posix.py", line 53, in get_config libraries = [ dequote(i[2:]) for i in libs if i.startswith(compiler_flag("l")) ] File "setup_posix.py", line 8, in dequote if s[0] in "\"'" and s[0] == s[-1]: IndexError: string index out of range
解决第三个问题
-
修改mysql的配置文件
mysql_config
,修改前记得cp一下
执行mysql_config
,查看一下路径 -
打开文件
vim mysql_config
,找到libs="$libs -l "
,改为libs="$libs -lmysqlclient -lssl -lcrypto "
libs="-L$pkglibdir" # libs="$libs -l " # 原来的 libs="$libs -lmysqlclient -lssl -lcrypto " # 更改后的 embedded_libs="-L$pkglibdir" embedded_libs="$embedded_libs -l "
-
再来一遍
pip install MySQL-python
-
终于成功了!可喜可贺!可喜可贺!
-
小心翼翼的试一下,
import MySQLdb
,真的成功了
发现第四个问题
-
开始使用的时候,发现自己用的是
python2.x
的环境,换成python3.x
继续用 -
在
import MySQLdb
的时候又出问题了,ModuleNotFoundError: No module named 'MySQLdb'
-
尝试使用
pip3 install MySQL-python
再安装一次,报错Collecting MySQL-python Using cached https://files.pythonhosted.org/packages/a5/e9/51b544da85a36a68debe7a7091f068d802fc515a3a202652828c73453cad/MySQL-python-1.2.5.zip Complete output from command python setup.py egg_info: Traceback (most recent call last): File "<string>", line 1, in <module> File "/private/var/folders/07/v8slhf9x5zsbbd8_9cd5ztnh0000gp/T/pip-install-oh_74ez5/MySQL-python/setup.py", line 13, in <module> from setup_posix import get_config File "/private/var/folders/07/v8slhf9x5zsbbd8_9cd5ztnh0000gp/T/pip-install-oh_74ez5/MySQL-python/setup_posix.py", line 2, in <module> from ConfigParser import SafeConfigParser ModuleNotFoundError: No module named 'ConfigParser' ---------------------------------------- Command "python setup.py egg_info" failed with error code 1 in /private/var/folders/07/v8slhf9x5zsbbd8_9cd5ztnh0000gp/T/pip-install-oh_74ez5/MySQL-python/
解决第四个问题
- 查到了原因,感到一阵阵的无语
In Python 3, ConfigParser has been renamed to configparser for PEP 8 compliance. It looks like the package you are installing does not support Python 3.
在Python3中,ConfigParser为了符合PEP8规范,已重命名为configparser。看起来你正在安装的软件包不支持Python3。 - 因为不支持python3,建议使用
pip install pymysql
,安装也没那么多套路 - 其实也找到了解决方案**(没有测试,我也不知道对不对,单纯的记录一下)**
-
方法一, 修改six模块为
try: import configparser except: from six.moves import configparser
-
方法二
cp /usr/local/lib/python3.7/configparser.py /usr/local/lib/python3.7/ConfigParser.py
