npm install only works when package is globally installed

I am on a Windows 10 machine and can only install npm packages globally. From the command prompt I can run:

npm install -g mocha

mocha

And there is no problem. When I install the package locally and run the command I receive the following error.

npm install mocha

mocha

'mocha' is not recognized as an internal or external command, operable program or batch file..

With a local installation of mocha, you can invoke it with:

node_modules/.bin/_mocha

try node_modules/.bin/_mocha -h

Caveat - You have to be in the directory where you installed it.

If you use npm scripts you will be able to use the binaries from the local installations. Simply add a script to your package.json file:

package.json

{
  ...
  "scripts": {
    "test": "mocha"
  }
  ...
}

And then to run it, simply do:

npm run test

For some commands, there are aliases, for example you can do npm start instead of npm run start and npm test instead of npm run test. But for all other scripts, you will have to do npm run <name>.

That's the way NPM works. The global installation path is the only path added to the environment variables. If you want to run something from a local install, try doing npm run <package>, so for your example, npm run mocha
