I attempted to execute the following commands:
$npm install mocha --save-dev
and then
$mocha
However, I received this error message:
$-bash: mocha: command not found
If I install it globally, it works. But is there a way to use a specific package version for this project only without installing it globally?
I am using a Mac with OS 10.11 El Capitan.
One way to execute local dependencies is by utilizing the npx command.
To test this out, run the following command:
npx jest
If you haven't set up mocha globally, you'll need to direct the terminal to your project's local directory
Try running this command instead:
./node_modules/.bin/mocha
This will execute the version of mocha that is locally installed within your project.
In order to utilize a command that is part of an NPM package, the global installation is necessary. You can achieve this by executing the following:
$ npm i -g mocha
If you prefer not to install it globally, an alternative is to use the local mocha command available at:
$ <app>/node_modules/.bin/mocha
$ navigate to the project_directory
If you have already listed the dependency in package.json file, then proceed with the following steps:
$ npm install
$ ./node_modules/.bin/<module-name> -V // to check the version
$ ./node_modules/.bin/<module-name> <action> // to utilize the module
In case you wish to add a new module, begin by executing:
$ npm install <module-name> --save-dev
Then, follow the commands to retrieve the version and implement the module. By doing this, you can configure and apply specific node_modules for a particular project, enhancing organization and sharing capabilities. For global installations of modules, run ->
$ npm install -g <module-name>
Alternatively, use sudo privileges as follows ->
$ sudo npm install -g <module-name>
I trust this information proves helpful :) :)
