Here are the steps that helped me yesterday to solve the problem:

1. Open package.json and remove the line where you define typescript dependency and its version
2. Remove node_modules folder
3. Remove package-lock.json file (if you use NPM 5+)
4. Run npm install typescript@latest --save
5. Run npm install

Hi, I had the same issue yesterday

Try to update your TypeScript dependency (should be ^2.4.0). npm i --save typescript

For me it completely solved the problem.
