[英]Error with command $python3 manage.py migrate
I'm new to Django and I am running Django inside a virtualenv on MacOS with python 3.6. 我是Django的新手,并且正在python 3.6的MacOS上的virtualenv中运行Django。 The command $python3 manage.py migrate but I keep getting an error asking me to install mysqlclient.
命令$ python3 manage.py迁移,但是我不断收到错误消息,要求我安装mysqlclient。

Did you install mysqlclient?
pip3 freeze looks like this: pip3冻结看起来像这样:
Django==2.0.1
mysqlclient==1.3.12
pytz==2017.3
Which other driver would I be able to use? 我还能使用哪个其他驱动程序? I am running it in the virtual environment that I created.
我正在我创建的虚拟环境中运行它。 Also
pip install MySQL-python
doesn't work on my Mac as python 2.7 comes pre-installed and to run Django 2.0, I installed Python 3.6 and for that when I run pip3 install MySQL-python
, I get an No Module named 'ConfigParser' error. 另外
pip install MySQL-python
在我的Mac上不起作用,因为预安装了python 2.7并运行Django 2.0,我安装了Python 3.6,为此,当我运行pip3 install MySQL-python
,我得到了一个名为'ConfigParser的No Module错误。
Try pip3 install Instead of pip install 尝试pip3 install而不是pip install
Since you are using python 3 由于您正在使用python 3
And check if python3-dev is installed in your system 并检查系统中是否安装了python3-dev
