Question

仅在PyCharm中，在调试模式下我看到以下错误（按“错误”按钮）。它没有达到断点，但是在加载flask.exe文件时失败。

C:\ProgramData\Anaconda3\envs\workflow_webapp\python.exe "C:\Program Files\JetBrains\PyCharm Community Edition 2018.3.2\helpers\pydev\pydevd.py" --multiproc --qt-support=auto --client 127.0.0.1 --port 55286 --file C:/ProgramData/Anaconda3/envs/workflow_webapp/Scripts/flask.exe run
pydev debugger: process 18788 is connecting

Connected to pydev debugger (build 183.5429.31)
Traceback (most recent call last):
  File "C:\ProgramData\Anaconda3\envs\workflow_webapp\lib\tokenize.py", line 390, 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:

    encoding = find_cookie(first)

    raise SyntaxError(msg)
SyntaxError: invalid or missing encoding declaration for 'C:/ProgramData/Anaconda3/envs/workflow_webapp/Scripts/flask.exe'

这里是debug configuration。

该应用在正常模式下运行正常：

> C:\ProgramData\Anaconda3\envs\workflow_webapp\python.exe
> C:/ProgramData/Anaconda3/envs/workflow_webapp/Scripts/flask.exe run  *
> Serving Flask app "workflow.py"  * Environment: production    WARNING:
> Do not use the development server in a production environment.    Use
> a production WSGI server instead.  * Debug mode: off  * Running on
> http://127.0.0.1:5000/ (Press CTRL+C to quit)

run configuration在这里。

版本为：

Python版本：Python 3.6.8 | Anaconda，Inc. | （默认值，2018年12月30日，18：50：55）在Win32上的[MSC v.1915 64位（AMD64）]
烧瓶版本：1.0.2
Pycharm：2018.3.2

任何指导将不胜感激。

SyntaxError：在烧瓶应用程序的调试模式下但在运行模式下无效或缺少编码声明
