PyInstaller exe file doesn't create log file

Question

I'm trying to make my scripts executable so I can send it to my colleague. I'm using PyInstaller.

pyinstaller --onefile main.py

Which creates two folders. When I open dist/main.exe, something is wrong but I don't know what because it doesn't create a log file. I can't figure out why. When I run main.py, the log file is created immediately.

Could you check it out?

Do you get any errors? Pls, check permissions in folder where you want to put the file. — Eugene Lisitsky, May 04 '17 at 13:46
@EugeneLisitsky The only thing I detected is Warning: WARNING: file already exists but should not: C:\Users\Milano\AppData\Local\Temp\_MEI95682\include\pyconfig.h — Milano, May 04 '17 at 13:50
@EugeneLisitsky I'm on Windows and I'm admin. I opened the main.exe using administrator and still the same problem. — Milano, May 04 '17 at 13:51
The pyinstaller onefile is actually unzipping the python scripts in a temporary folder (you see that in your error), which is also the current folder for your script. Your file should be generated in there. To fix that, try the logic of [this approach](http://stackoverflow.com/a/36456550/3837382). — Repiklis, May 04 '17 at 14:07

As you froze the application the File may be located under sys._MEIPASS

Here is a little example I tested in my application:

 if hasattr(sys, "_MEIPASS"):
            base_dir = os.path.join(sys._MEIPASS)
            print(base_dir)
            print(sys.argv[0])
>> C:\Users\Hendr\AppData\Local\Temp\_MEI986122
>> C:\Users\Hendr\Documents\coding_stuff\dist\test.exe

I have the same problem. The following scheme is feasible.

if hasattr(sys, "_MEIPASS"):                   
  print("base dir = ", sys._MEIPASS)
  CURRENTDIR = os.path.dirname(os.path.abspath(sys.argv[0]))
else:
  CURRENTDIR = os.path.dirname(os.path.abspath(__file__))

print('cur dir = ', CURRENTDIR)
