麻烦用pip3安装mysqlclient

问题描述

我正在尝试使用Django设置python 3.6环境.安装说明说我应该安装mysqlclient才能连接到mySQL.我明白了:

I'm trying to set up a python 3.6 environment with Django. The installation instructions say I should install mysqlclient to be able to connect to mySQL. I get this:

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文件应该是什么?当我尝试升级pip3时，我得到了:

mySQL is properly installed. What should be in the mysql_config file?When I try to upgrade pip3 I get this:

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

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，找不到它

After installing mysqlclient with pip3, I noticed that the module was installed in the python3.5 directory instead of in the python3.6 directory so when I tried to import the MySQLdb module running python3.6, it was not found

dennis@django:~/python_db$ python
Python 3.6.0+ (default, Feb  4 2017, 11:11:46)
[GCC 5.4.1 20161202] on linux
Type "help", "copyright", "credits" or "license" for more information.
>>> import MySQLdb
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
ModuleNotFoundError: No module named 'MySQLdb'
Error in sys.excepthook:

  File "/usr/lib/python3/dist-packages/apport_python_hook.py", line 63, in apport_excepthook
    from apport.fileutils import likely_packaged, get_recent_crashes
  File "/usr/lib/python3/dist-packages/apport/__init__.py", line 5, in <module>
    from apport.report import Report

    import apt
  File "/usr/lib/python3/dist-packages/apt/__init__.py", line 23, in <module>
    import apt_pkg
ModuleNotFoundError: No module named 'apt_pkg'

Original exception was:
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
ModuleNotFoundError: No module named 'MySQLdb'
>>>

然后我使用python 3.5重新运行并找到了它.如何使用pip3将模块安装到3.6目录中?

I then reran using python 3.5 and it was found. How do I install modules using pip3 into the 3.6 directory?

推荐答案

LDFLAGS=-L/usr/local/opt/openssl/lib pip install mysqlclient
