Despite being installed, the message 'concurrently: command not found' pops up

I'm attempting to run two scripts simultaneously, and I came across the concurrently package that is supposed to assist with this. After executing npm install concurrently --save and verifying it in my package.json, I faced an issue when trying to run it:

concurrently: command not found

I am puzzled as to why it cannot locate the package even though it has been successfully installed. I have followed the setup instructions outlined here, ruling out any mistakes in that regard. Previous solutions to this problem seem outdated. Is there a different method I can use to confirm its functionality, or should I explore other options?

Answer №1

When you use npm install to install a module without the -g flag for global installation, it gets installed in your project's node_modules folder. Any executable binaries within that module will be placed in node_modules/.bin, allowing you to run the local version of concurrently by executing node_modules/.bin/concurrently (or using $(npm bin)/concurrently from any directory in your project). Personally, I prefer relying on local dependencies specific to each project rather than installing globally, as it offers flexibility to use different versions in different projects.

If you add a script to the package.json "scripts" field, it automatically references these locally installed scripts without needing the full path, thanks to npm run including your project's node_modules/.bin in the system path.

If you encounter issues, start by checking the contents of the node_modules/.bin folder and confirming the existence of the binary associated with your script.

Answer №2

An interesting point to note is that the problem can arise when a folder name contains a dash "-". For example, (/developer/api-movies) or even (/developer-apps/apiMovies). It is recommended to use camelCase naming convention instead of dashes throughout your project.
