python3 manage.py dbshel​​l无法正常工作

Question

I am getting the following error while executing python3 manage.py dbshell on my mac.

Traceback (most recent call last):
  File "/Library/Frameworks/Python.framework/Versions/3.6/lib/python3.6/site-packages/django/db/backends/mysql/base.py", line 15, in <module>
    import MySQLdb as Database
  File "/Library/Frameworks/Python.framework/Versions/3.6/lib/python3.6/site-packages/MySQLdb/__init__.py", line 19, in <module>
    import _mysql
ImportError: dlopen(/Library/Frameworks/Python.framework/Versions/3.6/lib/python3.6/site-packages/_mysql.cpython-36m-darwin.so, 2): Library not loaded: libssl.1.0.0.dylib
  Referenced from: /Library/Frameworks/Python.framework/Versions/3.6/lib/python3.6/site-packages/_mysql.cpython-36m-darwin.so
  Reason: image not found

The above exception was the direct cause of the following exception:

Did you install mysqlclient?

I have already installed mysqlclient. I have looked at other answers on StackOverflow but none of them seems to work. Please help!

pip3 install mysqlclient Requirement already satisfied: mysqlclient in /Library/Frameworks/Python.framework/Versions/3.6/lib/python3.6/site-packages (1.3.12)

Answer 1

使用以下命令解决您的问题，

sudo apt-get install libmysqlclient-dev

Answer 2

I was finally able to solve it and hence I am writing a solution of my own question. This should work for anyone using MAC and Python 3.

I did the following:

Step 1: On terminal, I editted the ~/.bash_profile and added the following to the paths:

PATH="/Library/Frameworks/Python.framework/Versions/3.6/bin:${PATH}"
export PATH=${PATH}:/usr/local/mysql/bin
alias mysql=/usr/local/mysql/bin/mysql
alias mysql_config=/usr/local/mysql/mysql_config
export DYLD_LIBRARY_PATH=/usr/local/mysql/lib/
PATH="/usr/local/mysql/bin/:${PATH}"
export PATH

Step 2: Restarted the system. Changes only get affected after a restart.

This worked for me.
