The same error occurs for the whole 3.6.x series. 3.5 installs correctly, so does 3.7.

Installing yarn from sources doesn't help.

For context, this happened while installing @angular-devkit/[email protected].

Reproduction:

$ mkdir repro
$ cd repro
$ yarn set version berry
$ yarn init
$ yarn add [email protected]

Env (linux)

$ yarn --version
2.0.0-rc.32
$ node --version
v12.16.1

Thanks, also ran into this. 3.8 seems to work.

I was able to go around this issue by pinning down typescript resolutions in package.json

{
  // ...
  "resolutions": {
     "typescript": "3.9.5"
  }
}

May not work for all but should work for most.

Looks like typescript 3.9.5 works for me... sometimes.
In one of my projects it works, I see

typescript@patch:typescript@npm%3A3.9.5#builtin<compat/typescript>::version=3.9.5&hash=8cac75

In a different project yarn install is failing with message

typescript@patch:typescript@npm%3A3.9.5#builtin<compat/typescript>::version=3.9.5&hash=270b6c: Cannot apply hunk #6

I don't know why a different hash is being used for the same typescript major minor patch semver even after I clear the cache and remove the lockfile for both projects. Weird.

Do you have the same yarn version in both projects? Yarn patches typescript to add support for PnP.

[jamie-pate]

trying to install
"@angular-devkit/build-angular": "~0.901.4",
causes this because it depends on 3.6.5, there's no resolution that will work because 3.6.5 is the final 3.6 version.. how does something like this sneak in? this patch system seems flawed.... I'm not even using PnP

I hadn't thought about checking. Looks like the Cannot apply hunk #6 was when I was using yarn 2.0.0-rc.31, however the projects which were not failing used more recent versions.

Upgraded yarn via yarn set version latest and then install worked fine w/ typescript 3.9.5.

This should now be fixed in master. Note that the integration is slightly less good in 3.6 than 3.9+, so if you depend on TS yourself, we still suggest to upgrade.

[harrysolovay]

Still an issue.

yarn add [email protected]

[arcanis]

4.1.0 is still in beta, and any support for it is best effort. It literally just got merged in the trunk, so you'll have to use the master branch to install it.

[harrysolovay]

Thank you @arcanis !!!

[the21st]

Hey! Any updates on typescript 4.1 support? It's been out for 2 weeks now.

[arcanis]

The fix has been released last Monday, in 2.4
