Error when executing: "function Y_Env_Init[2]..Y_ServerStart"

What is the output of gvim --version | grep python? Make sure you run this on the version you've built for yourself.

I think I have a similar error, I see this each time on startup of yavide:

gvim --version:

Python 2 and 3 installed from Arch Linux repositories.

[JBakamovic]

Like it says in the error message, watchdog Python module is missing. Please try to install it via pip or system package manager and try to run yavide again. Though it should have been installed by the install.sh script. Many users for some reason miss this exact package.

[ChaoticEnigma]

Yes, that did it. Thank you.

[JBakamovic]

@ChaoticConundrum Glad you fixed it. Have you got any idea why this package wouldn't have been installed by the install.sh script? Did you notice any error during the installation process?

I've got plenty of such issues reported lately by different people. For me on Fedora it's working flawlessly but seems that is not the case on other distros. Which is strange because that package is being installed through pip which should be more unified way to install python dependencies ...

[ChaoticEnigma]

Actually, yes. It looks like install.sh installs python and python-pip, which on Arch Linux, are Python 3. From the packages installed for other distros, I am guessing you are trying to install Python 2? On Arch Linux, the Python 2 packages are python2 and python2-pip, and the pip command is pip2.

[JBakamovic]

Yes, that's correct. I am trying to install Python2 dependencies. I suppose I should try with pip2 instead. Different distros have different default Python versions which seems to cause problems. Thanks for your input.

I seem to only be getting this issue when I open a file using yavide., i.e. "yavide sample.cpp".
When I open yavide on its own, then open any file I never run into this issue. I have pip, pip2, pip2.7, pip3, pip3.5 and I already updated all of them and it doesn't seem to help.
