ERESOLVE could not resolve on npm install @uppy/svelte": "2.0.0" and @uppy/xhr-upload": "3.0.0"

Initial checklist

• I understand this is a bug report and questions should be posted in the Community Forum
• I searched issues and couldn’t find anything (or linked relevant results below)

Steps to reproduce

I have these in package.json:

"@uppy/svelte": "1.0.8",
"@uppy/xhr-upload": "2.1.2",

I'm trying to install:

"@uppy/svelte": "2.0.0",
"@uppy/xhr-upload": "3.0.0",

Expected behavior

It should install.

Actual behavior

But I'm getting this error:

What's the problem?

Hi, you want to have @uppy/core in your deps, otherwise you'll get conflicts if the version locally installed does not correspond to the one expected. Let me know if that helps.

It does not help.

In a new node project I'm trying to install those two dependencies. And boom! the error!

I think something is broken with deps.

In a new node project I'm trying to install those two dependencies. And boom! the error!

I think something is broken with deps.

I've tried it in a new project:

mkdir repro && cd repro
echo '{"dependencies": {"@uppy/svelte": "2.0.0","@uppy/xhr-upload": "3.0.0"}}' > package.json
npm i

I don't see any error, npm installs everything without problem.

I can reproduce if I first install the previous version though:

mkdir repro && cd repro
echo '{"dependencies": {"@uppy/svelte": "1.0.8","@uppy/xhr-upload": "2.1.2"}}' > package.json
npm i
echo '{"dependencies": {"@uppy/svelte": "2.0.0","@uppy/xhr-upload": "3.0.0"}}' > package.json
npm i # this errors

However adding @uppy/core to the list of dependencies does fix the error:

mkdir repro && cd repro
echo '{"dependencies": {"@uppy/svelte": "1.0.8","@uppy/xhr-upload": "2.1.2"}}' > package.json
npm i
echo '{"dependencies": {"@uppy/core":"3.0.0","@uppy/svelte": "2.0.0","@uppy/xhr-upload": "3.0.0"}}' > package.json
npm i # no errors

It looks like it's an npm issue, I can't reproduce with Yarn nor pnpm.

[frederikhors]

It works now. I removed the old, npm install and installed the new ones.

The update was the issue here. IDN why.

Thanks for the help.

OK good to hear 👍 Thanks for the report, I'll add a note in the migration guide about this.
