Error: Cannot find module 'uglify-es' since upgrading to 1.8.1

Hello all,

I just upgraded my forum instance from 1.8.0 to 1.8.1. I am now unable to start the forum.

I get the following error:

[cluster] Spinning up another process...

[cluster] Child Process (15609) has exited (code: 7, signal: null)

I followed the upgrade guide, then had this problem. Since then, I've tried the following fixes:

• npm install --production
• rm -rf node_modules; npm install --production
• npm i uglify-es (404 Not Found: uglify-es@latest)
• sudo chown -R www-data:www-data /var/www/friendos.club

I'm not sure what I can do to fix this problem. Any help would be appreciated. Thank you.

Update: Even though the upgrade docs say to skip step 4 if running a minor upgrade, I executed ./nodebb upgrade. That fixed my issue.

@ralphorama which upgrade docs say that?

I think running ./nodebb upgrade is actually applicable to all NodeBB versions now. Should make the appropriate changes to docs @PitaJ ...
