From https://github.com/Microsoft/vscode/issues/37217 **Problem** The install quick fix currently does a normal npm install. For cases where the version of npm used to manage a project is different than the version of npm found in the environment—npm 4 and npm 5 for example—this quick fix can also unexpectedly update the `npm-shrinkwrap.json`. Possible solution would be to run the `@types` install with `--no-shrinkwrap` --- Moving this issue over in case any one else want to weigh in here. We run into this in the VS Code codebase itself because we don't yet support npm 5
