Error loading package.json when no stable version

Hi!

I have a project which uses ts-node-dev as a dependency which apparently has no stable version. Whenever I load the package.json page, I’m seeing an error:

TypeError: Cannot read property 'split' of null
    at e.exports (index.js:3)
    at markCurrentVersionAndOutdated (package-utils.js:60)
    ...

which apparently is because there is no stable version of the package. Clicking the “add package” button also causes the entire application to crash.

If I remove the "ts-node-dev": "^1.0.0-pre.44", line, everything goes back to working fine.

Is this a known issue?

Use the reguler ts package.
