Suddenly all attempts to build any of my sites fail with the same issue as shown in the log attached. Here’s the log dump 12:55:26 PM: Build ready to start 12:55:38 PM: build-image version: d2c6dbeac570350a387d832f64bc980dc964ad65 (focal) 12:55:38 PM: build-image tag: v4.8.0 12:55:38 PM: buildb…

Hey @MartyNZ thanks for confirming. Since the error you’re seeing is happening before the build command can run, there is unfortunately not much we can see on our side as of now. If you enable verbose logging for NPM in the Environment Variables for your site, however, that should help because it w…

Hey @MartyNZ Unfortunately the deploy log is private. Are you able to post the contents of log here inside a code block?

Are you using a private repository, or private modules?

Interestingly all but one of the sites are now working again. The remaining one is a private repository (as they all are).

Node v16.15.1 (npm v8.11.0) breaks some builds To fix, simply revert back to v16.15.0 this is a setting that netlify sets and uses, so how do I change it? I’m running node v14.x.x on my development machine. I’m still having the same problem with several of my sites. I’ve reverted to manual d…

hi there @MartyNZ , please see this doc on setting node versions: [image] Manage build dependencies Specify dependencies for your project so that our platform can install required languages and software before running a build.

Thanks, I’ve looked into this. I’ve also updated all packages within the project to their latest version and tested the site in a dev environment. When tested locally there are no issues. I redeployed the updated site this morning and this is the error I got. 12:37:36 PM: Build ready to start 12…

I’m assuming you’re using private npm modules. Have you checked this: [Support Guide] Using private NPM modules on Netlify?
