我尝试用Django建立python 3.6环境。安装说明说我应该安装mysqlclient才能连接到mySQL。我得到了这个:
dennis@django:~$ sudo -H pip3 install mysqlclient
Collecting mysqlclient
Using cached mysqlclient-1.3.10.tar.gz
Complete output from command python setup.py egg_info:
/bin/sh: 1: mysql_config: not found
Traceback (most recent call last):
File "<string>", line 1, in <module>
File "/tmp/pip-build-4jiw3hvk/mysqlclient/setup.py", line 17, in <module>
metadata, options = get_config()
File "/tmp/pip-build-4jiw3hvk/mysqlclient/setup_posix.py", line 44, in get_config
libs = mysql_config("libs_r")
File "/tmp/pip-build-4jiw3hvk/mysqlclient/setup_posix.py", line 26, in mysql_config
raise EnvironmentError("%s not found" % (mysql_config.path,))
OSError: mysql_config not found
----------------------------------------
Command "python setup.py egg_info" failed with error code 1 in /tmp/pip-build-4jiw3hvk/mysqlclient/
You are using pip version 8.1.1, however version 9.0.1 is available.
You should consider upgrading via the 'pip install --upgrade pip' command.
mySQL已正确安装。mysql_config文件中应包含哪些内容?当我尝试升级pip3时,得到以下信息:
dennis@django:~$ sudo -H pip3 install --upgrade pip3
Collecting pip3
Could not find a version that satisfies the requirement pip3 (from versions: )
No matching distribution found for pip3
You are using pip version 8.1.1, however version 9.0.1 is available.
You should consider upgrading via the 'pip install --upgrade pip' command.
在使用pip3安装mysqlclient之后,我注意到该模块安装在python3.5目录中,而不是python3.6目录中,因此当我尝试导入运行python3.6的MySQLdb模块时,没有找到它
dennis@django:~/python_db$ python

>>> import MySQLdb

Original exception was:

然后我用python 3.5重新运行,找到了它。我如何用pip3把模块安装到python 3.6目录中?

在我的案例中,通过执行以下操作解决了该问题:
因为我使用的是Python 3.x,所以下面的代码也是必要的:

您可以尝试将mysql安装到特定的python目录,例如w/ python 3.6

查看这个老问题 (在查找其他内容时), 我发现问题可能是包含
mysql_config
的目录不在当前的$PATH中。显然,安装脚本就是用这个目录来查找它的。可能是“mysql to be installed”,但不在$PATH中-或者$PATH引用了错误的版本。
