When a package fails to install or publish, the npm CLI will generate an npm-debug.log file. This log file can help you figure out what went wrong.
If you need to generate a npm-debug.log file, you can run one of these commands.
For installing packages:
npm install --timing
For publishing packages:
npm publish --timing
You can find the npm-debug.log file in your .npm directory. To find your .npm directory, use npm config get cache.
npm config get cache
If you use a CI environment, your logs are likely located elsewhere. For example, in Travis CI, you can find them in the /home/travis/build directory.
