我正在尝试在便携式版本的 Django 中执行此操作：

from django.db import load_backend
myBackend = load_backend('django.db.backends.oracle') # or 'mysql', 'sqlite3', 'oracle'

但是，这会导致错误：Error loading cx_Oracle module: No module named cx_Oracle. 我认为这只是意味着cx_oracle没有安装。当我做了一个pip install cx_oracle（与需要的其他模块相同）时，它会导致此错误：

    Traceback (most recent call last):
      File "<string>", line 14, in <module>
      File "e:\PortableDjango\development\tools\virtualenvs\test_djangoproj\build\cx-Oracle\setup.py", line 132, in <module>
        raise DistutilsSetupError("cannot locate an Oracle software " \
    distutils.errors.DistutilsSetupError: cannot locate an Oracle software installation

    Complete output from command python setup.py egg_info:
    Traceback (most recent call last):
  File "<string>", line 14, in <module>
  File "e:\PortableDjango\development\tools\virtualenvs\test_djangoproj\build\cx-Oracle\setup.py", line 132, in <module>
    raise DistutilsSetupError("cannot locate an Oracle software " \
distutils.errors.DistutilsSetupError: cannot locate an Oracle software installation

我假设它正在寻找 Oracle 客户端，该客户端位于 PATH 变量中。我还忽略了什么，或者在可移植版本的 Django 中获得 Oracle 支持的最佳方式是什么？

您需要修改LD_LIBRARY_PATH以指向 Oracle 客户端库（lib目录）或 Windows - 下载相应的 windows 二进制文件。
