当文件从 IDE 运行时尝试 except 工作但是当用 pyinstaller 编译成 exe 时它不起作用

Question

I created a python tool with Tkinter GUI. These are the pieces of the script. The problem is with the try-except in these lines of code.

try:
   pldf_csv[data['sls_data']['add_columns']].write_csv(endpath,sep='\t')
except:
   write_eror_status = True
   print("CANNOT WRITE FILE")

If I run the python file via VSCode the try-except works like this

But then if I compile the script with pyinstaller to exe , those line doesn't execute at all

Since the error was raised when writing CSV with polars and polars has its own dependencies, when it's in exe form it needs to include --recursive-copy-metadata as per documentation pyinstaller --recursive-copy-metadata polars --onefile -w "myfile.py"
