npm ci floods "TAR_ENTRY_ERROR ENOENT" warnings; real error is "ENOTDIR: not a directory, mkdir '~/.npm'"
npm warn tar TAR_ENTRY_ERROR ENOENT: no such file or directory, open '.../node_modules/next/dist/compiled/...' npm error code ENOTDIR npm error syscall mkdir npm error ENOTDIR: not a directory, mkdir '/Users/<user>/.npm'
Point npm at a working cache directory, either for this run or permanently, or repair ~/.npm:
export npm_config_cache=/tmp/npmcache # per-shell
rm -rf node_modules && npm ci --no-audit --no-fund
# permanent: npm config set cache ~/.npm-cache (or move the bad ~/.npm aside and recreate it)
Symptom
npm ci in a Next.js project printed hundreds of lines like
npm warn tar TAR_ENTRY_ERROR ENOENT: no such file or directory, open '/.../node_modules/next/dist/compiled/react-dom/cjs/react-dom-test-utils.production.js'
and failed, leaving node_modules empty. Easy to miss at the bottom:
npm error code ENOTDIR
npm error syscall mkdir
npm error path /Users/<user>/.npm
npm error ENOTDIR: not a directory, mkdir '/Users/<user>/.npm'
npm error Log files were not written due to an error writing to the directory: /Users/<user>/.npm/_logs
Cause
npm's cache directory (~/.npm by default) was not a usable directory: a file or broken entry sat at that path. Every tarball extraction depends on the cache, so the TAR_ENTRY_ERROR lines are side effects, not the cause.
Verify
With npm_config_cache set, npm ci exited 0, and tsc --noEmit / next build ran against the fresh node_modules.
Notes
When an npm install fails with a wall of TAR_ENTRY_ERROR, read the last npm error lines first. ls -ld ~/.npm shows the problem straight away.
