What This Error Means
npm hit ENOSPC because the disk ran out of free space while extracting packages, writing cache data, or updating node_modules.
How to Fix It
Identify the path npm is failing on (look for the last referenced file path in the error output).
Free disk space and retry. Also check Docker/CI runner disk quotas if this happens in CI.
Retry after cleaning local state when safe (common:remove node_modules and retry install).
Why It Happens
The filesystem ran out of space while npm was extracting/writing files.
How to Verify
Re-run the original command and confirm the filesystem error no longer appears.
If this is a permission fix, confirm new files in node_modules are owned by the expected user.
Manual filesystem checks
Check disk space:df -h
Examples
npm ERR! code ENOSPCPrevention Tips
Keep npm cache and project directories owned by the build user.
Avoid running project installs as root unless you know exactly why you need it.
Ensure CI runners have enough disk space and sensible file descriptor limits.
Where This Can Be Triggered

This is a representative filesystem write path during npm operations. Filesystem codes like this are raised by Node/OS when this write fails. - GitHub
