Gatsby: Can't use gatsby develop on ubuntu

[pixelbreaker]

Description

Unable to use gatsby develop on ubuntu

Steps to reproduce

After cloning my new ubuntu machine (RIP apple) I've installed gatsby and run npm i which gave me a warning

npm WARN optional SKIPPING OPTIONAL DEPENDENCY: [email protected] (node_modules/fsevents):
npm WARN notsup SKIPPING OPTIONAL DEPENDENCY: Unsupported platform for [email protected]: wanted {"os":"darwin","arch":"any"} (current: {"os":"linux","arch":"x64"})

When I then run gatsby develop I get this error

success source and transform nodes — 0.401 s
success building schema — 0.139 s
success createPages — 0.035 s
error UNHANDLED EXCEPTION

Actual result

Could it be that you're running out of disk space? Because of ENOSPC in the error message. Also, unrelated, you should update gatsby-image to v2.

[pixelbreaker]

I doubt I'm out of space, it's a fresh install. Which got me to thinking it could be a permissions issue.

So I tried sudo gatsby develop which gave me a command not found error. Then I tried sudo npm run develop and that worked!

[stefanprobst]

Hmm, you really shouldn't run gatsby as root. Could you provide the specific steps how you (i) installed gatsby-cli and (ii) set up your project?

[stefanprobst]

And you could check if raising fs.inotify.max_user_watches helps, since the crash happens with createFsWatchInstance: sudo sysctl fs.inotify.max_user_watches=524288

[pixelbreaker]

@stefanprobst thanks, raising fs.inotify.max_user_watches seems to have fixed it! Now running as my own user fine. :ok_hand:

[stefanprobst]

Great! Note that setting this on the commandline is only temporary. To persist:

sudo -i
echo "fs.inotify.max_user_watches = 524288" > /etc/sysctl.d/99-local.conf

Issue seems resolved, so I'll close it

Something similar just happened with me as well when i was running npm run develop.
I mean the log had Error: ENOSPC: no space left on device, watch '/home/ammar/Desktop/mun-website/src'
I just ran gatsby develop and it worked. :thinking:
