接受这个问题的答案How to install/use cx_Oracle in PyPy说，为了在 pypy 上安装 cx_Oracle，我需要用--withmod-oracle参数编译它。如果我这样做，我将获得 cx_Oracle v. 5.0.0：

Python 2.7.3 (5acfe049a5b0cd0de158f62553a98f5ef364fd29, Jul 02 2013, 20:33:21)
[PyPy 2.0.2 with GCC 4.6.3] on linux2
Type "help", "copyright", "credits" or "license" for more information.
And now for something completely different: ``the way to avoid a workaround is
to introduce a stronger workaround somewhere else''
>>>> import cx_Oracle
>>>> cx_Oracle.version
'5.0.0'

不幸的是，django 不会运行它，因为没有 NCLOB：

./manage.py shell
File "/home/user/.virtualenvs/pypy_chembl_migration/site-packages/django/db/backends/oracle/introspection.py", line 13, in DatabaseIntrospection
cx_Oracle.NCLOB: 'TextField',
AttributeError: 'module' object has no attribute 'NCLOB'

我需要的是 cx_Oracle，版本 5.1.2。我怎么才能得到它？

Pypy wiki ( https://bitbucket.org/pypy/compatibility/wiki/cx_oracle ) 说 cx_Oracle 可以使用它。但我想我从那句话中得出了错误的结论：

pip install cx_Oracle -U

正如其他地方所讨论的，您似乎没有应用此页面中提到的补丁。
