I have copied npm caches onto a machine that has no internet access. When installing, it attempts to go online before falling back to the local cached versions and this seems to be slowing things down a lot:
npm install gulp -g --verbose npm info it worked if it ends with ok npm verb cli [ npm verb cli 'C:\Program Files\nodejs\node.exe', npm verb cli 'C:\Program Files\nodejs\node_modules\npm\bin\npm-cli.js', npm verb cli 'install', npm verb cli 'gulp', npm verb cli '-g', npm verb cli '--verbose' npm verb cli ] npm info using [email protected] npm info using [email protected] npm verb npm-session 85d023355611a2b7 npm WARN registry Unexpected warning for https://registry.npmjs.org/: Miscellaneous Warning ECONNREFUSED: request to https://registry.npmjs.org/gulp failed, reason: connect ECONNREFUSED 104.16.18.35:443 npm WARN registry Using stale data from https://registry.npmjs.org/ due to a request error during revalidation. npm http fetch GET 200 https://registry.npmjs.org/gulp 73192ms (from cache) npm timing stage:loadCurrentTree Completed in 73766ms npm timing stage:loadIdealTree:cloneCurrentTree Completed in 3ms npm timing stage:loadIdealTree:loadShrinkwrap Completed in 120ms npm http fetch GET 200 https://registry.npmjs.org/vinyl-fs 73164ms (from cache) npm http fetch GET 200 https://registry.npmjs.org/gulp-cli 73177ms (from cache) npm http fetch GET 200 https://registry.npmjs.org/glob-watcher 73180ms (from cache) npm http fetch GET 200 https://registry.npmjs.org/undertaker 73180ms (from cache) npm http fetch GET 200 https://registry.npmjs.org/anymatch 73116ms (from cache) npm http fetch GET 200 https://registry.npmjs.org/chokidar 73118ms (from cache) npm http fetch GET 200 https://registry.npmjs.org/async-done 73122ms (from cache) npm http fetch GET 200 https://registry.npmjs.org/normalize-path 73121ms (from cache) npm http fetch GET 200 https://registry.npmjs.org/just-debounce 73122ms (from cache) npm http fetch GET 200 https://registry.npmjs.org/is-negated-glob 73124ms (from cache) npm http fetch GET 200 https://registry.npmjs.org/object.defaults 73126ms (from cache)
All these 73s failures are taking forever.
Can I tell it "use the offline cache only" somehow? I'm running mpm 6.14.15 against node 14.17.6 due to some compatibility issues,

You can use the npm --offline flag
