When is V3 expected to be supported?

What do you mean? Vue 3 is already supported

@vue/cli 3.x still relies on the vue-jscodeshift-adapter.
When will this package be replaced with @vue/codemod?

[haoqunjiang]

I don't plan to add new features to 3.x. So it won't.

Brother, why(大哥，不是吧)? 😂

I created a tool that relies on both 3.x and 4.x. And the vue-jscodeshift-adapter may cause a mismatch between the vue and vue-template-compiler.
So would it be possible to support that in version 3，please

But vue-template-compiler is required in a Vue 2.x project. How does it become a problem?

[screetBloom]

Okay, let me describe the problem we're having.

• Generally, we will select a fixed vue/vue-template-compiler version number. For example, our team chose 2.6.11
• @vue/cli 3.x still relies on the vue-jscodeshift-adapter. And vue-jscodeshift-adapter has a vue-template-compiler@^2.5.13 installed by itself.
• That means vue-jscodeshift-adapter will try to install the latest version of vue-template-compiler when it is available. Such as 2.6.12
• This may cause a mismatch between the vue and vue-template-compiler

Personally, I wish @vue/cli would get rid of the third-party dependency on the vue-template-compiler@^2.5.13

[haoqunjiang]

1. Please use the resolutions field. As far as I tested, npm can correctly dedupe 2.6.11 and ^2.5.13, so only Yarn has this issue, and Yarn supports selective version resolutions.
2. Please consider update Vue to 2.6.12, it's basically the same as 2.6.11
