在PyCharm中配置Flask应用程序的调试器：“ UnicodeDecodeError：'utf-8'编解码器无法解码字节”

Question

我正在尝试在PyCharm IDE中为Flask应用程序配置调试器。

这是配置的样子：

从命令行手动运行应用程序，而无需在PyCharm中进行调试即可运行应用程序。当我在PyCharm中单击Debug按钮时出现问题。尝试运行后出现以下错误：

Traceback (most recent call last):
  File "C:\Users\username\AppData\Local\Programs\Python\Python37-32\lib\tokenize.py", line 385, in find_cookie
    line_string = line.decode('utf-8')
UnicodeDecodeError: 'utf-8' codec can't decode byte 0x90 in position 2: invalid start byte

During handling of the above exception, another exception occurred:

Traceback (most recent call last):
  File "C:\Program Files\JetBrains\PyCharm Community Edition 2018.2.4\helpers\pydev\pydevd.py", line 1664, in <module>

    globals = debugger.run(setup['file'], None, None, is_module)

    encoding, lines = detect_encoding(buffer.readline)
  File "C:\Users\username\AppData\Local\Programs\Python\Python37-32\lib\tokenize.py", line 426, in detect_encoding
    encoding = find_cookie(first)
  File "C:\Users\username\AppData\Local\Programs\Python\Python37-32\lib\tokenize.py", line 390, in find_cookie
    raise SyntaxError(msg)
SyntaxError: invalid or missing encoding declaration for 'P:/PROJECTS_PYTHON/messenger_chatbot/venv/Scripts/flask.exe'

您有什么想法可能出问题吗？
