SYNOPSIS
npm doctor [--registry registry]
DESCRIPTION
npm doctor runs a set of diagnostics to verify the npm environment is healthy. It checks: npm can reach the configured registry, the installed version of node and npm are supported, the npm cache is not corrupt, global and local bin directories exist and are on PATH, the packages tree has correct ownership, and the git binary is available.Each check is reported as OK or shows the specific problem. If any check fails, the exit code is non-zero.
INSTALL
sudo pacman -S npm
sudo apk add npm
brew install npm
CAVEATS
Some checks require network access. On restricted systems (CI, air-gapped), registry connectivity checks will fail. Cache verification can be slow on large caches.
