Question

我最近在运行python 2.7的Windows 2008 R2服务器上遇到深度复制错误。

即使是简单的pip安装-U selenium也会出现此错误

当我在python shell中运行命令mydriver = webdriver.Firefox（）时，我收到此错误

Traceback (most recent call last):

self.default_preferences = copy.deepcopy(
AttributeError: 'module' object has no attribute 'deepcopy'

导入pandas时出现类似错误。

当你运行Python脚本的文件夹中存在copy.py或copy.pyc时，就会发生这种情况。因此，当您import copy实际导入工作目录中的copy.py时。请确保不要使用copy.py作为您的文件名。

pip install，pandas，selenium中的Deepcopy错误，无处不在
