ts-jest is not installed properly

[Tallyb]

The package.json configuration
"bundleDependencies": false,
is incorrect (array expected), and cause ts-jest to be incorrectly installed under inner node_modules, which in some cases may cause jest not to find it. Should be installed on top level node_modules

[thymikee]

Can you elaborate on this? I'm not sure what's this about

[Tallyb]

bundleDependencies structure has changed to contain an array. The value false is not valid.
I use npm 5.0.3 and the ts-jest was installed under jest-preset-angular/node_modules and not directly under node_modules.
I now see that this property is generated in my installed package.json, and does not exist on the original one, so it may be some local configuration that is misbehaving.
I am closing this issue.

Well, I'm having the same issue here. ts-jest is expected under node_modules/ts-jest -- but actually lives under node_modules/jest-preset-angular/node_modules/ts-jest. I'm assuming it has either something to do with npm v5, or some other updated dependency.

I got it working by:

• moving the jest.config.json Jest configuration file to the project root folder (before it was in a config subfolder)
• installing ts-jest into the root node_modules folder by adding it as a devDependency to my project

Still, this seems like an actual issue - but I'm not sure where the issue comes from (this preset, ts-jest, jest) ...

Does it happen with npm v3/4 or Yarn?

[Tallyb]

I am not using yarn, and it happened to me also with npm 4. Also with the new npm 5.2.0
@dominique-mueller - do you use it in a lerna project?

[Tallyb]

@thymikee maybe upgrading the tyoescript dev dependency will do the trick?

[thymikee]

@dominique-mueller you need to specify rootDir if your config is not in the root of your project (from where you run Jest). It's a bug in Jest 20, still unresolved

[thymikee]

@Tallyb my dev dependencies are not affecting your deps

[dominique-mueller]

@thymikee I'll try that one out, thanks!

[dominique-mueller]

@thymikee Awesome, defining the rootDir fixed it! Thanks so much!
