我正在关注 django 教程,很多人都问过这个问题,但我认为我的情况有点独特,因为在安装 python-mysql 后,当我尝试执行 python manage.py syncdb 时仍然出现此错误,
我在 virtualenv 中,因为我使用 macports 来管理我的 python 安装我创建了我的 virtualenv
virtualenv code/vdjango --no-site-packages --python=/opt/local/bin/python
在此之前使用 macports 我安装了 django py27-django
,但是在创建了我的 virtualenv 之后,我认为将 django 安装到 virtualenv 上会更好,所以我使用了pip install django==1.5
根据 django 教程,我编辑了我的 settings.py 文件,然后执行 python manage.py syncdb,我最终得到以下错误:
[~/code/vdjango/newsite]$python manage.py syncdb

为了确认我已经安装了 python-mysql 包,我再次运行了 pip install,
(vdjango)mac-pro@localhost:[~/code/vdjango/newsite]$pip install python-mysqldb
Downloading/unpacking python-mysqldb
Could not find any downloads that satisfy the requirement python-mysqldb
No distributions at all found for python-mysqldb
Storing complete log in /Users/mac-pro/.pip/pip.log
那么这里发生了什么?看起来我拥有进一步学习本教程所需的一切,但有些 python/django 抱怨没有 mysqldb。
