"Gruntfile.js" tasks...ERROR >> Error: Cannot find module 'fork-ts-checker-webpack-plugin'

Grafana Plugin Development

Hi, I’m committing some changes to a recent pull of grafana/grafana:master, but for some reason now when I try to commit, I get the following error:


 ↓ Running tasks for *.{ts,tsx} [skipped]
   → No staged files match *.{ts,tsx}
 ↓ Running tasks for *.scss [skipped]
   → No staged files match *.scss
 ✔ Running tasks for *pkg/**/*.go

>> No "jscs" targets found.
Warning: Task "jscs" failed. Use --force to continue.

Aborted due to warnings.

husky > pre-commit hook failed (add --no-verify to bypass)

All I’ve done is checkout the most recent master from the grafana repo, made a couple changes to some /pkg/ go files, and tried to git commit -m "blah". I’m not really sure what these checks do, so am tempted to --force, but I ultimately want to submit a pull request to the grafana repo with these changes, so I think I should get around this properly. Any help is appreciated.

Try yarn install to get latest npm dependencies

I gave that a shot already, but ended up with the following:

yarn install --pure-lockfile
yarn install v1.5.1

@ctote Did you manage to resolve this error?

@acedev - Yes, I did. Here’s a related link: The engine "node" is incompatible with this module. Expected version ">=6.0.0". · Issue #131 · gilbarbara/react-joyride · GitHub

The quick (nuclear) option is to just add --ignore-engines to your yarn command. The more correct solution (given in the link) is to:

check your node version with:

$ node -v

check your npm version with:

$ npm -v

Open package.json and make sure the values you got from running the two commands above match with the versions of ‘node’ and ‘npm’ on the document. Mine didn’t so I just changed the values, saved and everything worked fine.
