The project cannot start after the `vue add vue-next` command is executed

[happyGloria]

• Dev environment:

1. vue-cli: @vue/cli 4.4.1
2. node：v12.18.3

• Repetition steps:

1. vue create <project-name>
2. npm run dev
   result: the project works properly.
3. vue add vue-next
   result:
   1. "@vue/compiler-sfc"和“vue-cli-plugin-vue-next” added in to package.json

4. fixed： cnpm install -D vue-template-compiler
   ps: I know that this approach is not feasible. The vue-template-compiler is run under vue2.x;
   result: version conflict

I have the same problem:

What should I do to fix this error?
