3.0.0-rc.11 peer dependency update is a breaking change

[tim-white87]

Version

3.0.0-rc.11

Node and OS info

all

Steps to reproduce

If your version is set to allow minor updates, for example: "@vue/cli-service": "^3.0.0-rc.10", then when you install, you get version 3.0.0-rc.11. The move of vue-template-compiler to the peer dependencies broke the build

npm WARN @vue/[email protected] requires a peer of vue-template-compiler@^2.0.0 but none is installed. You must install peer dependencies yourself.

What is expected?

Premajor changes shouldn't break build

What is actually happening?

Premajor change added a peer dependency that is breaking the build.

---

This is fixable by adding this to the deps or pegging the version explicitly.

Thanks!

RC version bumps are not patch changes.

Also, all vue-cli projects, even created before RC11, come with vue-template-compiler explicitly listed in the project package.json, so I don't see how this could possibly break your build, unless you are talking about @vue/cli-service-global.

Ahh yea you're right, should have said premajor. It started happening in AWS CodeBuild initially, so I tried a rebuild with a previous working build, and this one broke too. I took a look locally and did a clean checkout & npm install and I was able replicate. I believe npm will still install the latest premajor version with the ^. Should we peg this to an explicit version then?

The project was created a few months ago with the vue cli, not sure which exact version (I think beta-5) so the ^ got carried over from that. I updated it for rc-10 and must have missed the npm warning.

Once we release official 3.0 ^ will be fine as we will stick to semver and avoid breaking changes. Also this change was technically not breaking between RCs. It broke because of an upgrade from beta-scaffolded project.

Word, thanks man! I was trying to align the code to the latest so we are ready for the stable 3.0 without much effort.

Really appreciate all your work on vue & the cli by the way! We are using it for all our new projects, its just phenomenal all around.
