A lot of Linux and macOS newcomers to NodeJs got a problem with NPM installer: Either run npm install -g <package_name> under sudo privilege or install the package locally to the project (under node_modules folder) and call it via full path or npx. Fortunately, there’s a simple workaround that takes you less than a minute to solve the puzzle.
Just open your Terminal and make sure the location is your $HOME directory. If it isn’t, you’ll need to use the so familiar “cd” to change the directory to your $HOME folder. Then copy and paste this simple line to the current open Terminal and hit Enter or Return to start:
Npm run build Builds the app for production to the build folder. It correctly bundles React in production mode and optimizes the build for the best performance. user@server $ ll total 4 -rwx- 1 user user 2608 Jul 15 18:23 qa.sh However, when I attempt to run it with sudo it says it can't find it: user@server $ sudo./qa.sh sudo password for user: sudo: unable to execute./qa.sh: No such file or directory This is on a fresh build. No changes have been made which would cause problems.

That’s all. Everything must work in the exact way we expect. Tada! Enjoy!
What’s Node.js® and NPM?
Node.js® is a JavaScript-based environment which you can use to create web-servers and networked applications. You can also use it to perform helpful tasks on your computer such as concatenating and minifying JavaScript files and compiling Sass files into CSS.
NPM is a “package manager” that makes installing Node “packages” fast and easy. A package, also called a module, is just a code library that extends Node by adding useful features. For example, the “request” module simplifies the process of making HTTP requests so you can easily get web resources from other sites.
NPM is installed when you install Node.js®

Although there is a Mac installer program on the Node website, we recommend using Homebrew to install and update Node.
Prerequisites
- You should have some familiarity with the Mac Terminal application since you’ll need to use it to install and test Node and NPM. You’ll also need the Terminal to use Node.js and NPM. The Terminal application is located in the Utilities folder in the Applications folder.
- Dependencies. Although you can install Node in other ways, we recommend using Homebrew. Homebrew lets you avoid possible security problems associated with using the
sudo
command to install software like Node and Node modules.- Install Homebrew. Follow the steps on the How to Install Homebrew on a Mac instruction guide to install Homebrew.
Installation Overview
Installing Node.js® and NPM is pretty straightforward using Homebrew. Homebrew handles downloading, unpacking and installing Node and NPM on your system. The whole process (after you have Homebrew installed) should only take you a few minutes.
Installation Steps
- Open the Terminal app and type
brew update
. This updates Homebrew with a list of the latest version of Node. - **Type
brew install node
. - Sit back and wait. Homebrew has to download some files and install them. But that’s it.
Test it!
Make sure you have Node and NPM installed by running simple commands to see what version of each is installed:
- Test Node. To see if Node is installed, type
node -v
in Terminal. This should print the version number so you’ll see something like thisv0.10.31
. - Test NPM. To see if NPM is installed, type
npm -v
in Terminal. This should print the version number so you’ll see something like this1.4.27
