Error [ERR_REQUIRE_ESM]: require() of ES Module ... not supported.

[marikaner]

We use cliui transitively through jest, which is a CJS module. Currently, when running jest in our project, we get the following error:

Error [ERR_REQUIRE_ESM]: require() of ES Module [...]/node_modules/string-width/index.js from [...]/node_modules/cliui/build/index.cjs not supported.

I believe this is because of these lines.
Instead string-width and string-ansi, string-width-cjs' and string-ansi-cjsshould be required. Those are already installed. However, the third dependencywrap-ansi` does not exist as a CJS dependency.

Short version: Are you using yarn 1? Try upgrading to yarn v1.22.22 or higher.

Long version

The problem isn't actually in this repo. Or at least, not yet.

PR #139 uses package aliases to pull in two different versions of string-width et al to add wrapping support for esm. It is published as @isaacs/cliui from a cliui fork and is used as a dependency of JackSpeak. The aliases can trigger broken dependency resolution with Yarn 1.

With a closer look I realized the problem might not be this package because I got the same issue with another. I was in fact using yarn 1.22.19. Thanks for the tip!

i use yarn in version 1.22.22 and the problem still persists

Have you got a reproduction @achimstraussdmb2bcom ?
In case you did not already, you may need to delete an existing lock file and node_modules and do a fresh install to clear the problem.

I was struggling with this issue, I'm not 100% sure what solved it but in the end I got it working on yarn 1.22.22 only after deleting yarn.lock and node_modules

I had the same issue, updating to yarn 1.22.22 and this fixed it:

rm -rf node_modules yarn.lock && yarn install

I've just updated to 1.22.22 and it was enough to solve the issue, I was facing this ERR_REQUIRE_ESM on Vite + React +Jest setup
