This will make the Express command-line available in all projects. In these cases, the command varies slightly: $ sudo npm -g install PACKAGEįor example, to install Express, you would execute: $ sudo npm -g install express In other cases (typically when the module installs a command line tool), it is more convenient to install the packages globally. To install modules locally, you just have to execute this command: $ npm install PACKAGEįor example, to install MySQL, you would execute: $ npm install mysql This ensures all the required dependencies are installed and won’t break when installing other packages in a different project or locally. It installs the packages in a node_modules subdirectory of the current working directory, usually a project folder. The newer versions of Node.js are released very frequently. npm -v 6.13.1 The above output shows that you have installed Node.js version 12.4.0 and NPM 6.9.0 on your macOS system. NPM is used for managing modules of Node.js on your system. The local installation is recommended, as the size of the packages is usually small. Also, find the installed version of NPM installed with Node.js.

Npm installs modules in two different scopes: local and global. Using it, you can install, uninstall and search for Node.js modules. It saves a lot of development time by just switching to the version of nodejs comes with the npm package manager. Node Version Manager (NVM) is a great tool and easy to switch between multiple node versions while working on projects that required different NodeJs versions. To completely remove nvm from the system. To use installed nodeJs version in the system nvm use system Or can be used below command nvm exec 8.11.1 node app.js Other Commands Remove the Alias nvm unalias awesome-project Run to specific NodeJs version, without switching nvm run 8.11.1 app.js nvm alias awesome-project 12.13.1Īfter creating an alias, then switch to the alias nvm use awesome-project
We can create an alias as per the Project basis or the group of projects using the same NodeJs version. Use Custom alias for installed NodeJs versions Switching Between installed NodeJs Versions nvm use 8.11.1 //To enable 8.11.1 nvm use 12.13.1 //To enable 12.13.1
#HOW TO INSTALL NODE JS MAC WINDOWS#
nvm install 8.11.1 // to install the 8.11.1 version nvm install 12.13.1 //to install the 12.13.1 version UnInstall the multiple NodeJs version nvm uninstall 8.11.1 Switching the NodeJs version Get a List of installed NodeJs version nvm list //for windows nvm ls //for MacOs/linux Multiple NodeJs version can be installed using the below command. Verify Installation command -v nvm Usage Get a List of all available NodeJs versions nvm ls available //windows nvm ls-remote //MacOs/Linux Install latest NodeJs version nvm install node Install latest LTS Release nvm install -lts Install particular NodeJs version
Verify Installation nvm version MacOs/Linux Installation of NVM Windowsĭownload nvm-setup.zip and install on the windows NVM allows installing multiple node js versions on the same machine and switching between the required node js version. To overcome this problem, we can use the Node Version Manager (NVM). While working on the multiple projects of NodeJs, you might be required to run different projects on the different nodejs version or for the legacy nodejs projects, you might require an old version of the nodejs, and the others required a new version of node-js, or to checkout the new feature of nodejs, you need to install the latest version of node jsĪs on the same machine, we can only install one version of the nodejs, so it's very painful to uninstall and install the new node version as per your project requirements.
