This error occurs when npm's cache verification process encounters a missing file or directory. ENOENT stands for "Error NO ENTry"—npm expected to find a cache file, directory, or metadata but it doesn't exist. Cache verify checks the integrity of npm's cached packages and can fail if the cache structure is corrupted, partially deleted, or inaccessible. The npm cache stores previously downloaded packages to speed up future installations. As of npm v5+, the cache is designed to be self-healing—it detects corruption and automatically refetches data as needed. However, missing files or metadata in the cache index itself can cause ENOENT errors that prevent verification from completing.
First, identify where your cache is stored:
npm config get cacheOn Windows, the default is %LocalAppData%\npm-cache.
On macOS/Linux, the default is ~/.npm.
Attempt to repair the cache using npm's built-in verification:
npm cache verifyThis command checks the contents of the cache folder, garbage collects unneeded data, and verifies the integrity of the cache index. npm will attempt to repair any discrepancies found.
If cache verification doesn't resolve the issue, force clear the entire cache:
npm cache clean --forceThis deletes all cached data and forces npm to refetch packages on next install.
If the above commands don't work, manually remove the cache directory:
Linux/macOS:
rm -rf ~/.npmWindows (PowerShell):
Remove-Item -Recurse -Force $env:LOCALAPPDATA\npm-cachenpm will recreate the directory on next use.
If the cache contains root-owned files, change ownership to your user:
sudo chown -R $(whoami) ~/.npmAvoid using sudo npm—this causes permission issues. Consider reinstalling via nvm instead.
How npm cache works: npm stores packages in a content-addressable cache directory named _cacache. All data is verified for integrity both when stored and when retrieved.
Cache verification internals: npm cache verify checks the cacache index, validates checksums, and garbage collects orphaned entries. It runs offline and doesn't require network access.
Race conditions: Older npm versions (pre-5) had race condition bugs where concurrent operations could partially delete cache files.
CI/CD considerations: In Azure Pipelines and similar systems, ensure cache directories are created before npm operations.
