Python:在执行代码时获取跟踪错误

Question

当我以bzt test.yml的形式运行代码时，我得到的是错误。在一切正常之前。

C:\etc\tmp\my-test>more test.yml

Answer 1

听起来像是丢失或损坏了lxml包。

解决办法如下：

1. 尝试金牛座安装程序
2. 通过pip重新安装lxml和/或bzt包。

查看：

• 金牛座:测试自动化工具星座中的新星 有关详细设置说明。

如果问题仍然存在，请使用bzt.log文件内容更新您的问题。

Answer 2

ImportError: No module named elementtree.ElementTree

你确定不应该

import xml.etree.ElementTree as etree

否则，检查是否安装了此依赖项，或者在当前项目中是否存在与导入查找有关的“元素树”文件夹。
