python-3.x - 模块“剪辑”没有属性“SetExternalTraceback”
问题描述
我们尝试在 python 2.7 中使用剪辑-v6.3、kivy-v1.11.1 运行此代码。我们得到的错误是在线main(sys.argv)说“模块剪辑没有属性 SetExternalTraceback”。我们认为出现这个问题是因为我们的系统中没有安装 pyclips。但是在安装 pyclips 时，我们面临以下问题。
当我们尝试安装从https://pypi.org/project/pyclips/#files下载的 pyclips-1.0.7.343.tar.gz以运行此代码时。但是我们遇到了一个问题，即从 Microsoft 网站下载 Microsoft Visual C++ 9.0。我们成功安装了它，然后它也给出了这个错误。

解决方案
回溯表明该模块正在使用 python2 打印语法，因此与 python3 不兼容。
你的标题中的错误没有出现在你的帖子中，所以我不知道那是什么，但它可能与这个核心问题无关。
