This is a reproduction for a bug where ensurePackage does not work with typescript. Even after typescript is installed, Node still cannot resolve it unless you re-run the script.

Steps

1. Try node index.js and see that it fails the first time.
2. Call node index.js a second time and it works.

Note: if you remove node_modules first then the script works. It seems to be a problem when node_modules exist but typescript is not found.

Notes

• moment also fails.
• If you try a different package it also works: node index.js date-fns.
• If you remove the require.resolve(pkg) call then the script works the first time as well.
