@MacGregor_Thomson It looks like the block executable currently doesn’t

report a few critical errors. It’s hard to say whether you’re experiencing the

same bug as me, but it’s worth a shot.


Generally, the executable will exhibit this behavior if its “file watching”

mechanism fails. There are many ways this could happen; here are two

possibilities and steps you can take to work around them:



  • you’ve exceeded the maximum number of files that your operating system is

    configured to allow. This may be because you’ve been running for a long time

    or because the default settings are too conservative. Resolution: restart

    your computer or follow this guide to configure your system to allow more

    “watched” files     (that second option only applies for folks using GNU/Linux)

  • you have a non-readable file or directory in your “block” directory.

    Resolution: claim ownership of all files in that directory. On Unix-like

    systems, you can do this from the command-line by running the following

    command in the “block” directory: chown -R $(whoami) . (that’s a period at

    the end)

Thanks @Mike_Pennisi! Indeed I needed to increase the inotify limit

I am running into the same issue on ubuntu 18 with node v12.11.1. I ran debug and got almost the same output talking about express router, but with my path info in the beginning.

Your fixes got me up and running. I’m now up and running after chowing the block project directory and its contents, and updating my file watching limit. Thanks!
