mysql-python安装错误

标签： django django-rest-framework mysql-python

我正在用mysql设置django rest项目。我安装了所有依赖项，包括mysql-python：

       -r, --rebase[=false|true|merges|preserve|interactive]
           When true, rebase the current branch on top of the upstream branch after 
fetching. If there is a remote-tracking branch corresponding to the upstream branch 
and the upstream branch was rebased since last fetched, the rebase uses that 
information to avoid rebasing non-local changes.

我需要进行一些调整，如此处Mac pip install mysql-python unsuccessful

所述

现在，当我尝试运行Django==1.11.12 djangorestframework==3.8.2 django-cors-headers==2.2.0 drfdocs==0.0.11 mysql-python==1.2.5 django-rest-auth==0.9.3 django-allauth==0.35.0 nltk==3.2.5 django-extensions==2.0.7 pyparsing==2.2.0 pydot==1.2.4 时，出现以下错误：

python manage.py migrate

为什么会这样？我在Mac上，并且也安装了MySQL。
