Django - installing mysqlclient error: mysqlclient 1.3.13 or newer is required; you have 0.9.3

问题

I've trawled the forums but cannot find an answer or even any documentation on this.

On running the command:

python manage.py inspectdb

I get the error:

mysqlclient 1.3.13 or newer is required; you have 0.9.3

I have tried all the suggested fixes including: -upgrading pip -installing a different wheel (32 bit instead of 64), namely mysqlclient-1.4.2-cp37-cp37m-win32.whl with the command pip install mysqlclient-1.4.2-cp37-cp37m-win32.whl (this works fine without an error but doesn't do the job required!)

My objective is to simply connect a legacy mysql database (running inside of XAMPP and myphpadmin) to Django. I've followed the documentation which misses out the need to install mysqlclient, and have got stuck at this point.

This is how I fixed it.

Go to your django/db/backends/mysql installation dir. Check your path in the error message.

I'm using pipenv so my path is:

/home/username/.local/share/virtualenvs/project-env/lib/python3.7/site-packages/django/db/backends/mysql

Open file base.py and search for:

version = Database.version_info

Put a pass inside if and comment line:

raise ImproperlyConfigured('mysqlclient 1.3.13 or newer is required; you have %s.' % Database.version)

Like this.

if version < (1, 3, 13):
   pass
   '''
   raise ImproperlyConfigured(
       'mysqlclient 1.3.13 or newer is required; you have %s.'
       % Database.__version__
   )
   '''

Save, close this file and open operations.py.

Search for:

query = query.decode(errors='replace')

and change decode to encode

query = query.encode(errors='replace')

Now, try to run the server.

I have had the same issue as lower version of mysqlclient was installed due to pymysql.

OS: Linux Mint 19.1

Python: 3.6.8

Django: 2.2.2

1. Uninstall mysqlclient: pip3 uninstall mysqlclient
2. Uninstall pymysql: pip3 uninstall pymysql
3. Install mysqlclient: pip3 install mysqlclient

回答3:

this problem occurs when you create Django project in pycharm by default settings. It's caused by the default version of django is 2.2.6, so just downgrade the django version to 2.1.7, and error in the terminal is gone.

pip install Django==2.1.7

that's all!

回答4:

Instead of edit internal configuration, try to upgrade the version of mysqlclient

pip3 install -U mysqlclient

回答5:

1. Install wheel:

   pip install wheel

2. Download file that you want from here: https://www.lfd.uci.edu/~gohlke/pythonlibs/#mysql-python

3. Move to your Downloads directory (I guess it'll be cd Downloads)

4. Install downloaded file with: pip install <file name>

WARNING!! You CANT edit name of downloaded .whl file. It contains some information what is required to install.

I had a similar issue, I was getting

"django.core.exceptions.ImproperlyConfigured: mysqlclient 1.3.13 or newer is required; you have 1.3.12."

So I went to the C:\Users\username\Envs\env\Lib\site-packages\django\db\backends\mysql, opened base.py and changed that line...

if version < (1, 3, 13): 

to...

if version < (1, 3, 10):

which is a version lesser than mine and it worked.

回答7:

If it's not critical for you, as a variant, just downgrade your django framework from 2.2.2(for example) to 2.1.

回答8:

There are the same issue on github. Solution that perfectly fits for me is here.

I just quote an author:

I first pip uninstall pymysql (as it seems it doesn't work anymore)

Then I've used pip install mysqlclient

Last, I checked all my "pymysql" imports and deleted them.
