Ghost Upgrade NPM Cannot Run in WD Error

I am trying to upgrade to Ghost 0.7.9 and followed the directions of upgrading to a node version 4.2.x < 5.x.x (My version is 4.7.3) and had no issues following all of the steps until I reached having to runnpm install --production for some reason I'm getting
npm WARN cannot run in wd ghost@0.7.9 npm install semver && node -e "require('./core/server/utils/startup-check.js').nodeVersion()" (wd=/var/www/ghost) and can't seem to figure out a solution. I'm running my droplet via SSH with a root user. Could it be my root user permissions for NPM?

Full run:

npm WARN cannot run in wd ghost@0.7.9 npm install semver && node -e "require('./core/server/utils/startup-check.js').nodeVersion()" (wd=/var/www/ghost)

> jsonpath@0.2.2 postinstall /var/www/ghost/node_modules/jsonpath
> node lib/aesprim.js > generated/aesprim-browser.js


I also tried running npm cache clean and rm -rf node_moudles, but still received the same result. Any help or guidance?

Not sure if this detail helps, but I followed the chown -R ghost:ghost core command presented in step 6 of the ghost upgrade documentation and curious if that impacted the root user that I'm logged in as. Would it?

At the end of the message, does it by chance echo out killed? I ask as this is common on VPS's with lower resources. Since npm tends to use quite a bit of resources when initially installing all modules expected by an application (i.e. RAM/Memory), if you run out, it'll simply kill off the process and fail.

So if you're running this on a 512MB Droplet, and you see killed, that's one potential reason. If this is a 1GB Droplet, last I tested, Ghost will install without any issues, though if you're still seeing killed, then you may have to upgrade to a 2GB.

If you're not seeing killed echo'ed out, if you run it adding --unsafe-perm to the end, does it work?

  • @jtittle this does not echo out killed. It also appears that the node_modules are installed correctly despite this error as I didn't have any issues running the applications with exception of having to individually install sqlite3, Not sure if that helps, but this doesn't seem to be a major issue preventing running the applicaiton
