由于 cx_oracle 无法运行 django 服务器

Question

我在 github 中拉我朋友的代码，当我想用​​ django 运行它时

*path*>workon test
(test)*path*>py manage.py runserver 

这是我得到的错误

Traceback (most recent call last):
  File "C:\Users\u532246\Envs\test\lib\site-packages\django\db\backends\oracle\base.py", line 47, in <module>
    import cx_Oracle as Database
ModuleNotFoundError: No module named 'cx_Oracle'

During handling of the above exception, another exception occurred:

django.core.exceptions.ImproperlyConfigured: Error loading cx_Oracle module: No module named 'cx_Oracle'

我已经把oracle模块放在了系统设置里面，但是还是不行，不知道是不是我放错了文件还是有什么我没有设置让它工作

已经找到解决办法了：

1. 检查您的 python 是否与 cx_oracle 具有相同的位，也许 cx_oracle 将安装与您的操作系统相同的位。

2. 如果它没有相同的位，你必须像你的操作系统一样下载相同的位，如果是 64 位，那么你的 python 必须是 64 位
