Lost remote after 10000ms - Issue connecting to zerorpc server after packaging python

[spsvision]

After packaging the python executable with Pyinstaller, I suddenly have issues with the zerorpc server. It appears that my issue comes after execFile the python executable. I'm able to create the pyprocess, but it isn't able to connect to the python script as it did before when it was just spawning off the script.

This is the exact error: D:_\pyCal\renderer.js:14 Error: Lost remote after 10000ms at Object.createErrorResponse (D:_\pyCal\nodemodules\zerorpc\lib\util.js:53) at ClientChannel.

Same problem here.

I appreciate all the effort and hardwork put in by you @fyears . This is a great open source project and is quite helpful.

I am getting the same error as mentioned above except after i package the app, it is not able to connect to the server. Do you have any suggestions for this ? @fyears

[rishantagarwal]

I tried running the executable directly and it fails with error

I am also getting same issue, it seems zerorpc don't work in exe file. Anyone found solution?

[brainytwoo]

Not sure if the issue is exactly the same but I was getting the same error. I fixed it by installing zerorpc via pip. pip install zerorpc

I compared an old working package to a newer one that didn't work, and noticed that some folders and files were missing. I'm not sure which of the following fixed it for me, but here's what I did:

• Uninstalled every other python version that I had
• Reinstalled Python 3.6.3, installed it for every user and chose to install pip, tcl, tkinter, with precompiled standard library
• Reinstalled all the other libraries with pip, such as pyinstaller, requests, etc
• Reinstalled pypiwin32 with pip

For reference, here's a comparison between a working and non working file/folder structure

I also experienced this issue when completing the tutorial with Windows 10. The specific problem I experienced was with the .bind method. The python program (bundled as an .exe file with pyinstaller) stopped immediately without logging any errors when it called the .bind method. When I used pdb.set_trace() to debug the issue, this is what I found when stepping through the program:

> .\dist\add\add.exe 4242

How I fixed it:

Originally I used Python 2.7 to install Zerorpc and pyinstaller. When I switched to Python 3.7 (in a virtualenv), it worked! I'm not sure why upgrading python version fixed the issue.
