When you create project for first time and you want to have latest version of node_modules, delete dependencies and devDependencies block in package.json.
After that, launch following commands.
$ npm install --save request @types/node @types/requestor
$ yarn cache clean
$ yarn add request @types/node @types/requestnpm install --save-dev @types/fs-extra browserify coveralls exorcist fs-extra istanbul@next mocha mocha-typescript rxjs rimraf ts-node tslint typescript unit.jsor
$ yarn cache clean
$ yarn add @types/fs-extra browserify coveralls exorcist fs-extra istanbul@1.1.0-alpha.1 mocha mocha-typescript rxjs rimraf ts-node tslint typescript unit.js --devThese packages are the minimal required to execute the project.
You can install after that all needed packages in dependencies or devDependencies to perform your project.
