python - 属性错误 : 'module' object has no attribute 'getargspec' while running a main python file of the flask project

Question

当我尝试运行我的 flask 项目的 python 文件时。我得到 AttributeError:

'module' object has no attribute 'getargspec'

**Scenario 1:** When tried running the python file of my flask project
    -bash-4.2$ python ./main_service.py
    Traceback (most recent call last):
      File "./main_service.py", line 1, in <module>

这个错误与 flask 有什么关系吗？虚拟环境？尝试卸载并重新安装 python。但是，无济于事。感谢对解决问题的评论。提前致谢!!!!!!

Answer 1

正如@CristiFati 所说，您有一个与 Flask 正在使用的东西同名的文件。您需要查看堆栈跟踪以查找代码库中的任何内容，在您的情况下提到了 token.py

如果我这样做(在 shell 中)，我会得到类似的错误:

mkdir test
cd test
echo "print('in token.py')" > token.py
python -c 'import flask'

如果我删除这个文件，错误就会消失。
