For instance, when you are creating a Node.js module, you can use require to access it.Ĭreate a file and name it index.js, and add the following code: // index.jsĬonsole.log("successfully required a package")
NPM CONFIG SET LOCAL INSTALL
Once you have run npm install and the package is in the node_modules directory, it can be used in your code. However, if a package.json file exists, npm will install the latest version that satisfies the semver (semantic versioning ) rule that is declared in the package.json. If a package.json file does not exist in the local directory, the latest version of the package will be installed. Which Version of the Package is Installed? MacOS, Ubuntu, Debian > npm install express
Take for instance that you install a package called express, you can confirm that it worked correctly by checking that a node_modules directory now exists and that the directory has a subdirectory named express. If you want to confirm that npm install worked correctly, you should check to see that a node_modules directory exists and that it has a directory for the package(s) that you have installed. This creates the node_modules directory in your current directory (if one doesn't exist yet) and downloads the package to that directory. You can download a package with the command below: npm install When you want to use a package as a command line tool, (like grunt CLI), then you have to install it globally.You should install locally when you want to depend on the package from your own module, using something such as Node.js' require.So when should you install globally and when should you install locally: Local installation of packages is not the only way to install packages, we can also install packages globally.
