python 使用Flask 出现 ValueError: Expected object or value 问题解决

问题描述：经过各种百度，搜资料，发现了这样的问题。这里记录一下，以防以后再犯这样的错误。我用pandas来读取json文件调试是正常的。服务跑起来是出现这样了这样的错误。首先我的manager.文件与我处理数据的py文件不在同一级目录。文件结构大致如下： project clean_data data.py test.json manager.py templates static test.json文件是与data.py文件在同一级目录下的。所以我读取json文件的时候，用的是相对路径。而manager.py运行的时候就会导致在它的当前同级目录下找不到这个test.j

This error message is typically seen in Python when a try statement is used without an except or finally block. A try statement is used to handle exceptions that may occur during the execution of a block of code. If an exception occurs, the program will jump to the except block to handle the exception. If there is no except or finally block, the program will not know what to do if an exception occurs and will raise this error message. To fix this error, you need to add an except or finally block to handle the exception. For example: ``` try: # some code that may raise an exception except SomeException: # handle the exception finally: # this block will run regardless of whether an exception was raised or not ``` Note that the except block should specify the type of exception that you want to handle. If you do not specify a type of exception, the except block will catch all exceptions, which is generally not recommended.
