This module will attempt to reinstall any missing dependencies. It can be called via the command line or used programmatically.


An NPM module to reinstall missing dependencies.

I created this module after working on a project where deployments were failing due to missing module dependencies. An npm install would fail to install the required dependencies for an unknown reason and without error. Since npm install succeeds without error, there wasn't a way to tell if the dependency installation failed.

When running npm install for a second time on a project, npm will check the first level of modules to ensure they're installed, but not traverse the dependency tree to ensure all sub-module dependencies are installed. You can run npm outdated to check if modules are missing but npm won't install them for you.

This module combines npm outdated and npm install to install all missing dependencies within the dependency tree.

To be able to use this tool system-wide to install missing dependencies for all your node projects, install it globally.

npm install -g npm-install-missing

Within your project directory:


The script will check the current project directory for missing dependencies and install them automatically.

This module depends on the following modules:

  • async
  • npm

To install the devDependencies and run the test framework:

cd npm-install-missing
npm install
npm test
