i get this when i open pyinstaller builded exe file
[1219/004030.604:ERROR:icu_util.cc(133)] Invalid file descriptor to ICU data received.

I tried: https://github.com/cztomczak/cefpython/blob/master/examples/pyinstaller/README-pyinstaller.mdstep by step , but still get this error

and also , i spend whole day use google search , but still not find solution(actually find out some solution, but that work for Linux or Mac)

i tried lower version Python 3.6.7 but still get this error

i dont know this error is about my computer or dev environment?

[Czarek Tomczak]

What version of PyInstaller?

Does the original unmodified pyinstaller example work fine?

[Buff]

C:\Users\Buff\Desktop\test>pyinstaller -v  3.4   (ty u comment btw)

[Czarek Tomczak]

See the pyinstaller example README for specific instructions. Install pyinstaller 3.2.1 as it is recommended, other versions were not tested.

i try pyinstaller3.2.1 and my python back to 3.5.4 but still get this error.

[Buff]

i tried  https://github.com/cztomczak/cefpython/blob/master/examples/pyinstaller/README-pyinstaller.md and working right now,
I thought related with .spec config . but currently i dont know which one
is tough for me , cuz im noob, ill learning it

I'm facing the same issue, Czarek, could you please help us.

I got the same issue. I solved it by copying "icudtl.dat、locales、cef.pak、cef_100_percent.pak……" into the .exe directory.

we can use 'pip show cefpython3' to find out where the files are. For example, my cefpython3 path is "c:\users\baight\appdata\local\programs\python\python38\lib\site-packages". So we can find the files in "c:\users\baight\appdata\local\programs\python\python38\lib\site-packages\cefpython3".

I am not sure which files should copy, so I copied all of them, except "_pycache__"、"examples"、"swiftshader"、"__init__.py"、"debug.log"、"License"、"README.txt"……, that obviously not need.
