下次尝试运行
下一次尝试运行
PS C:\Users\Fowler> pytest --version
注意事项:
- 我正在使用Windows 10。
- 通过“挂起”,我指的是等待pytest --version返回至少5分钟...
- 在等待pytest期间,python.exe在我的计算机上使用了100%的逻辑处理器。
- 我使用Windows安装程序卸载了所有Python安装程序,并尝试重新安装了Python 3.8.0以修复问题。
- 仅当我不使用虚拟环境时,pytest才会失败。 因此,使用venv pytest确实有效。
- 但是,在vscode中使用venv进行调试会出现奇怪的“Session-1超时等待debuggee生成”错误。虽然你可能认为“debuggee”这个词会是一个很好的提示,但在google上并没有发现太多与此相关的内容。我猜这是一个不同的问题,但也许有关连?
- 总之,我无法使用venv调试Python,也无法在没有venv的情况下运行pytest单元测试。 可能,这些问题是不相关的...但是,由于这种进退两难的局面,我将非常感激任何解决这些问题的提示。
当我按下<ctrl-c>
退出pytest的“挂起”状态时,会显示以下内容(每次结尾都会略有不同?):

最后!哇,为了帮助理解,这是一张照片,显示Python进程在pytest.py期间大量占用我的CPU...
如果有任何帮助或想法,我将不胜感激!
atomicwrites
现在只在Windows上使用,而我没有Windows机器来测试任何东西。根据回溯信息,看起来pytest
可能正在尝试写入大量文件。例如,您可以尝试编辑“C:\ Users \ Fowler \ AppData \ Roaming \ Python \ Python38 \ site-packages \ _pytest \ assertion \ rewrite.py”,第274行
以添加打印语句以查看它正在尝试写入什么。(您还可以使用类似procmon的工具来监视Python并查看它正在做什么?)。 - nneonneotempfile.py
文件中。如果出现访问冲突(例如临时文件名与临时目录相同),则会无限重复。首先,为什么有人将重复计数设置为2 ** 32...即使将循环设置为20次尝试,它仍然失败。其次,tempfile尝试在每个已安装的第三方包的每个__pycache__
目录中创建文件,例如colorama
,toml
等等。这是什么鬼?第三,我禁用了访问冲突时的重试,然后pytest在10次运行中有5次失败...现在的问题是如何修复Python核心,并与谁讨论此问题? - Paebbels
