先生：
test_test.py：

import main

def test_file() -> None:
    main.main("qfqsdfsqdds")
    assert True

main.py：

from tqdm import tqdm

def main(username: str):
    for i in tqdm(range(10)):
        a = i + 1

通过PyCharm运行测试会引发以下错误：

test_test.py::test_file PASSED                                           [100%]

不过，在终端上运行pytest是可行的。
问题似乎确实来自tqdm。
我使用Python 3.11.1和：

PyCharm 2022.3.1 (Community Edition)
Build #PC-223.8214.51, built on December 20, 2022
Runtime version: 17.0.5+1-b653.23 amd64
VM: OpenJDK 64-Bit Server VM by JetBrains s.r.o.
Windows 11 10.0
GC: G1 Young Generation, G1 Old Generation
Memory: 2030M
Cores: 16
Non-Bundled Plugins:
    me.lensvol.blackconnect (0.5.0)
    com.chesterccw.excelreader (2022.12.1-203.223)
    com.github.copilot (1.1.38.2229)

正如@aaron所指出的，PyCharm的堆栈跟踪可能有一个巨大的错误，因为当我单击"关于"时，它确实显示2022.3.1，而当我运行代码时，堆栈跟踪显示2022.1.3。

它使用cp1252.py-编码，直到它找到一个序列，它不能用这个编码（正如你指出的可能与tqdm有关）。编码与Windows有关，所以它不能被aaron（macOS）和我（Linux）复制是有道理的。
如果你能给它python执行的参数，那么this可能会有帮助，这个想法是强制它使用utf-8编码，参数为-X utf8，你可以在Run -> Edit Configurations...中的Interpreter Options下添加这个参数，用于py-test。

看起来它只需要default encoding in windows，您可以在PowerShell中检查您的系统上是否确实存在这种情况：

[System.Text.Encoding]::Default

这个插件的github页面上有很多问题，这个变通方案看起来值得一试：
"只需将以下行添加到所有包含测试的文件的开头："

# -*- coding: utf-8 -*-

也许你也可以试试这个，但是我认为它只适用于控制台输出，并且不会覆盖插件的默认值。
1.在"设置/首选项"对话框（Ctrl + Alt + S）中，选择"编辑器|一般情况|控制台。
1.从默认编码列表中选择默认编码。（将其更改为utf-8）
1.单击"确定"应用更改。
