Not being able to make Eel work with Electron

[Andres-celi]

Hello, I have been trying to get Eel to run on Electron with no luck.

import eel options = { 'mode': 'custom', 'args': ['node_modules/electron/dist/electron.exe', '.'] } if __name__ == "__main__": eel.init('app') eel.start('index.html',mode='electron')

Options are not being used anymore because of the update. But I get the following error:

Traceback (most recent call last): File "/home/pi/main.py", line 298, in eel.start('index.html',mode='electron') File "/home/pi/.local/lib/python3.5/site-packages/eel/init.py", line 142, in start show(*start_urls) File "/home/pi/.local/lib/python3.5/site-packages/eel/init.py", line 170, in show brw.open(start_urls, _start_args) File "/home/pi/.local/lib/python3.5/site-packages/eel/browsers.py", line 64, in open browser_module.run(path, options, start_urls) File "/home/pi/.local/lib/python3.5/site-packages/eel/electron.py", line 11, in run sps.Popen(cmd, stdout=sys.stdout, stderr=sys.stderr, stdin=sps.PIPE) File "/usr/lib/python3.5/subprocess.py", line 640, in init errread, errwrite) = self._get_handles(stdin, stdout, stderr) File "/usr/lib/python3.5/subprocess.py", line 1135, in _get_handles c2pwrite = stdout.fileno() io.UnsupportedOperation: fileno

I have gone through the various posts in here and well. Nothing has worked for me so far. I would love some help.

Thank you

Hi @Andres-celi. Based on the example here, it looks like you should be passing in options as eel.start('index.html', options=options). At the moment you're creating an options dict but not using it anywhere.

This might give you deprecation warnings, though. You should probably go for the following:

eel.start('index.html', mode='custom', cmdline_args=['node_modules/electron/dist/electron.exe', '.'])

Hi @samuelhwilliams thanks for the response. As I mentioned, among others, I tried that approach too. If I use the following:

eel.init('app1') eel.start('index.html',mode='custom', cmdline_args=['node_modules/electron/dist/electron.exe', '.'])

I get this: Traceback (most recent call last): File "/home/pi/main.py", line 298, in eel.start('index.html', mode='custom', cmdline_args=['node_modules/electron/dist/electron.exe', '.']) File "/home/pi/.local/lib/python3.5/site-packages/eel/init.py", line 142, in start show(*start_urls) File "/home/pi/.local/lib/python3.5/site-packages/eel/init.py", line 170, in show brw.open(start_urls, _start_args) File "/home/pi/.local/lib/python3.5/site-packages/eel/browsers.py", line 53, in open stdout=sps.PIPE, stderr=sps.PIPE, stdin=sps.PIPE) File "/usr/lib/python3.5/subprocess.py", line 676, in init restore_signals, start_new_session) File "/usr/lib/python3.5/subprocess.py", line 1282, in _execute_child raise child_exception_type(errno_num, err_msg) FileNotFoundError: [Errno 2] No such file or directory: 'node_modules/electron/dist/electron.exe'

and this is the path contents:

pi@alba2:~/app1/node_modules/electron/dist $ ls chrome_100_percent.pak libGLESv2.so resources.pak chrome_200_percent.pak libvk_swiftshader.so snapshot_blob.bin chrome-sandbox libvulkan.so swiftshader electron LICENSE v8_context_snapshot.bin icudtl.dat LICENSES.chromium.html version libEGL.so locales vk_swiftshader_icd.json libffmpeg.so resources

electron is in there :/

On the other hand, if I use this:

eel.init('app1') eel.start('index.html', mode='custom', cmdline_args=['/home/pi/app1/node_modules/electron/dist/electron', '.'])

it runs and then nothing. No errors and no app either. Is this an improvement? Not really sure Lol.

I think this is just a .bat script which points to the actual .exe. Popen needs the path to the .exe, it can't deal with the .bat

I thought the mode='electron' should deal with all this though... You shouldn't need to specify the path yourself. Are you in the latest version?

[ChrisKnott]

Sorry wait are you on Mac? (Got confused by the .exe ref).

Either way, it should work to just say mode='electron' with no further options

[Andres-celi]

Hello @ChrisKnott , my bad for not clarifying. I am using a Raspberry Pi 3 B+. When I use mode='electron' I get the following error:

Traceback (most recent call last): File "/home/pi/main.py", line 299, in eel.start('index.html',mode='electron') File "/home/pi/.local/lib/python3.5/site-packages/eel/init.py", line 142, in start show(*start_urls) File "/home/pi/.local/lib/python3.5/site-packages/eel/init.py", line 170, in show brw.open(start_urls, _start_args) File "/home/pi/.local/lib/python3.5/site-packages/eel/browsers.py", line 64, in open browser_module.run(path, options, start_urls) File "/home/pi/.local/lib/python3.5/site-packages/eel/electron.py", line 11, in run sps.Popen(cmd, stdout=sys.stdout, stderr=sys.stderr, stdin=sps.PIPE) File "/usr/lib/python3.5/subprocess.py", line 640, in init errread, errwrite) = self._get_handles(stdin, stdout, stderr) File "/usr/lib/python3.5/subprocess.py", line 1135, in _get_handles c2pwrite = stdout.fileno() io.UnsupportedOperation: fileno

So the way I went is the following:

eel.init('app1') eel.start('index.html',block=False, mode='custom', cmdline_args=['/home/pi/app1/node_modules/electron/dist/electron', '.']) os.system('electron app1/main.js --disable-gpu'+ " &")

this starts the webserver on python, but then opens the electron app from cmd line. It works but I was wondering if the app should open by itself?. By the way I am using the last version available of eel.

Are you using IDLE?

[samuelhwilliams]

I'm going to close this now based on inactivity. It does seem to be an IDLE error from quick googling ... hopefully you've found and fixed the problem now.
