ts-jest: ts-jest 26.1.2 - "cannot find source file"

yes, running jest --clearCache allows the test to pass, but then changing the value again (e.g. to qum = 'quo') causes it to immediately fail again

👋🏽just hit this same issue in VSCode, I can workaround by running jest --clearCache && jest, so it’s not a blocker. I was just wondering about the ETA of a new release

v26.1.4 is out, I will close this issue

This bug is still present in the latest version, at least with Next.js serverless functions.

I also use the latest version and had this problem, only in watch mode, the normal tests passed perfectly. After clearing the cache it was fixed.

v26.1.4 is out, I will close this issue

Happening again on OSX ^26.1.0

Downgrading to ^25.5.1 solves the issue

I have the same issue with all my typescript projects since the update to 25.3.1. After a successful test run, as soon as I change anything in a source file and run the test again, I get the same error. Reverting the change allows the test to complete.

At the moment, all I can do is keep running jest --clearCache every time I change something, or roll back to a previous version of ts-jest.

I set up an example repo that mimics my project setup if it’s of any use: https://github.com/rav2040/ts-jest-error-could-not-find-source-file

I included a GitHub CI test workflow in the repo. If you look at the workflow logs you’ll see the test managed to complete even after I changed the value of ‘foo’ in the source file.

However, when I do the same thing on my own machine I get the following:

 FAIL  __tests__/index.test.ts
  ● Test suite failed to run

    Could not find source file: '/mnt/f/dev/projects/ts-jest-error-could-not-find-source-file/__tests__/index.test.ts'.

I also tried cloning the repo to a Digital Ocean droplet and running it there, and I still got the same error.

Upgrading to the latest (^25.5.1 at the time of writing) solved the issue for me. Thanks!

@mordigann228 you can: either use 25.2.1 or use clear cache or wait for the next release 😃

thank you guys for the information, will look into it asap. Stay tune 😃

Updated: would you guys please test the fix with this tgz file https://drive.google.com/open?id=1QRnkDOIy7BXQdSjcybzveBkmE1uCU8h5

Still present, cleaning cache doesn’t solve, google drive links in this thread are useless as they can be deleted.

@ahnpnl using this version right now, so far so good. Thank you for your support

Hi @magwas, @x87, @dwjohnston, @lmanerich, @impulse

v26.1.4-alpha.0 is out with the fix. Would you guys please test it by install ts-jest@next ?

If it works, I will publish a new release and close this issue.

Let me know

do you use watch mode or non-watch mode ? Hmm I tried renaming but I don’t see the issue either. I might know how to fix it but need reproduce steps that can verify the fix.

I think the steps are:

• Run test with cleared jest cache
• Rename the a test file
• Change something in the one of the imported modules (the modules which the test file imports)
• Run test again and error will be thrown

you need to clear jest cache, not npm cache

@ahnpnl updating to v26.1.3 solved the issue. Was with v26.1.2 and “jest:26.1.0”. Thanks

thank you guys, will open a PR for it.
