That happened with me when I removed the directory on one terminal, but was in it on another. Just cd out of it and then back helped.

probably combined with running npm cache clean to get any busted packages out of your cache.

npm WARN saveError EACCES: permission denied, open '/package-lock.json.577729328'

package-lock.json is automatically generated for any operations where npm modifies either the node_modules tree, or package.json

Conceptually, the "input" to npm-install is a package.json, while its "output" is a fully-formed node_moduleshttps://docs.npmjs.com/files/package-locks

npm WARN saveError ENOENT: no such file or directory, open '/package.json'

sudo npm install npm@latest -g

• Create a package.json file and store it in the folder where you will install the npm package. Keep it simple for now. This npm video helped me. Also read Using a package.json for additional information. The following example satisfies the minimum requirements:
  {
  "name": "demo-app",
  "version": "1.0.0"
  }

rm -rf /usr/local/lib/node_modules
brew uninstall node
brew install node --without-npm
echo prefix=~/.npm-packages >> ~/.npmrc
curl -L https://www.npmjs.com/install.sh | sh
