referencing the cjs version instead of the esm version?

[addlistener]

Check the code here https://github.com/yargs/cliui/blob/af3145da0ea31738c4715865a6da0ee388a94c74/lib/cjs.ts#L3-L5

Should we require strip-ansi-cjs instead of strip-ansi?

Here are my errors

What version of string-width is being used by cliui in your project? Check with npm ls string-width.

In theory it should be string-width@4.2.3 which is not esm.

https://github.com/yargs/cliui/blob/af3145da0ea31738c4715865a6da0ee388a94c74/package.json#L52

The output looks like yarn. I did a quick check and and also saw expected version of string-width:

$ yarn add yargs
...
$ yarn why string-width
├─ cliui@npm:8.0.1
│  └─ string-width@npm:4.2.3 (via npm:^4.2.0)
│
├─ wrap-ansi@npm:7.0.0
│  └─ string-width@npm:4.2.3 (via npm:^4.1.0)
│
└─ yargs@npm:17.7.2
   └─ string-width@npm:4.2.3 (via npm:^4.2.3)

Yes you are right

[shadowspawn]

Is your problem resolved now @addlistener ? (I think it might be from your comment, but making sure!)

[addlistener]

Hmmm...not really. I switched to commander instead

@shadowspawn but thanks for the kind response. The problem occurred when trying to pack the program with https://github.com/vercel/pkg

The pkg packer is trying to pack with commonjs. However string-width is not commonjs. I remember trying aliasing string-width to string-width-cjs and it worked.

[shadowspawn]

Thanks for the clues @addlistener There is a PR open to rework the cjs/esm wrapping support (#143), so the packaging issues if not fixed are likely to be different if that lands!

If you have a reproduction @archonic (saw your thumbs up), feel free to open another issue with new information.

I have the same problem.

I ran yarn add -D concurrently@^8 and then tried to run:

concurrently "yarn next dev" "tunnel.sh" and got this output:

/code/myproject/node_modules/cliui/build/index.cjs:315
undefined
             ^

Thanks.

@ryancwalsh Try upgrading to yarn v1.22.22 or higher. See #159

[ryancwalsh]

@shadowspawn Interesting!

I had seen that post already but I know I had upgraded yarn recently and thought I had the latest version (and below you'll see why).

But when I ran yarn -v I saw 1.22.19.

https://github.com/yarnpkg/yarn/tags shows versions up to 1.22.22.

People at https://github.com/yargs/cliui/issues/159#issuecomment-2128009693 say that 1.22.22 helps.

So I ran npm upgrade --global yarn (again, if that's the way I originally tried to upgrade and had assumed worked).

But upon closer inspection I guess it did nothing.

Because now that I double-checked (because of your message), I see yarn -v still shows "1.22.19".

Then I found https://stackoverflow.com/a/55278430/470749 and ran yarn policies set-version which successfully upgraded yarn.

Then I ran:

rm -rf node_modules/ && rm yarn.lock 
yarn && yarn dev

And it works!

You were right.

I apologize for wasting your time. And I appreciate how quick and helpful your response was!
