There are two ways to clean up the node_modules folder: Delete the folder and reinstall. Use npm prune (starting with npm version 6)
The error in NPM, 'error package install failed, see above', can occur when the user creates a new project in Angular using Node. js using VS code. This means that NPM is corrupted in your system, and must reinstall NPM.
Run npm update -g npm. Execute this command by running the command prompt as Administrator npm install -g windows-build-tools. Run npm install inside the project folder where the package. json file is located, if it doesn't work run: npm install --force.
download the file https://registry.npmjs.org/express/-/express-4.9.7.tgz
then install from the file
npm install ./express-4.9.7.tgz
