Unable to compile TypeScript

[Izhaki]

Did npm install had any errors?

Can you see the folder node_modules/@types/jasmine?

No, everything installed fine and I've got the jasmine types. I think it's a problem with ts-node on my system. I'll try and get it working on a different machine.

Thanks for your help.

ts-node in this repo should run the local version, so doubt this has anything with your machine.

The first thing I'd try is to pin the dependencies in package.json (just remove the ^ before each dependency - my mistake not doing this), rm -rf node_modules, npm install and see if it works.

If this fails, I can see from your log you're using Linux 4.10.6-100.fc24.x86_64, but if you give me the exact distribution and version, I can test this very quickly using Docker.

On a separate note, technology-wise this repo is somewhat outdated. If you just want to get quickly off the ground, then I guess using it is OK.

But I owe to say that if you're after something more long-term than nyc is the way to go - if I understand correctly, it's Istanbul's newer product for running coverage reports, and seems to be working very very well. Study this issue and the links within for more.

Also, since I've started using webpack I didn't look back (despite a rather steep learning curve), and that I'd vote for Mocha over Jasmine for serious projects. Jasmine is simple and great, but Mocha falls better into the 'compossible technology' paradigm, which I'm a strong believer of. It also has somewhat larger eco-system and a webpack driver.

Just my 2 cents (let me know if you want me to create a sample repository for this - I just need to copy-paste and clean an existing project).

Pinning the dependencies fixed it, thanks. I've had the same problem with ts-node in other projects and it seems like getting the right versions of different packages is the key.

I've used Jasmine in the past and was looking for a simple test setup with Typescript but I'm definitely interested in looking at Mocha. If you could do a sample repo that would be great.

Thanks again for the help and advice.

I had a go at a basic setup and it works quite well.
