升级到 MacOS Big Sur 后，我试图重新安装我的虚拟环境。
但出现错误：

[root@localhost cx_Oracle-5.2]# /opt/python2.7/bin/python setup.py install
Traceback (most recent call last):
File "setup.py", line 170, in <module>
raise DistutilsSetupError("cannot locate an Oracle software " \
distutils.errors.DistutilsSetupError: cannot locate an Oracle software installation
但是实际上我不需要此服务器上的Oracle，我的Oracle服务器是远程的。我怎么解决这个问题？
