Last week I had nothing wrong on creating a new project and serving it, but today when I use vue/cli to create a new default project, I got a compile error when serving.
PS E:\Projects\testing> yarn serve
yarn run v1.22.5
$ vue-cli-service serve
INFO Starting development server...

ERROR Failed to compile with 1 error 下午12:22:33

I can serve all my old projects correctly, then I try to reinstall different versions of vue/cli and nodejs, but nothing change.
currently my nodejs version: v14.17.0
vue/cli: 4.5.13
What should I do?
I somehow solved this error by editting reactivity.esm-bundler.js in node_modules/@vue/runtime-core/dist/
class RefImpl {
_rawValue;
_shallow;
_value;
__v_isRef = true;
constructor(_rawValue, _shallow) {
this._rawValue = _rawValue;
this._shallow = _shallow;
this._value = _shallow ? _rawValue : convert(_rawValue);
}
get value() {
track(toRaw(this), "get" /* GET */, 'value');
return this._value;
}
set value(newVal) {
if (hasChanged(toRaw(newVal), this._rawValue)) {
this._rawValue = newVal;
this._value = this._shallow ? newVal : convert(newVal);
trigger(toRaw(this), "set" /* SET */, 'value', newVal);
}
}
}
after:
class RefImpl {
constructor(_rawValue, _shallow = false) {
this._rawValue = _rawValue;
this._shallow = _shallow;
this.__v_isRef = true;
this._value = _shallow ? _rawValue : convert(_rawValue);
}
get value() {
track(toRaw(this), "get" /* GET */, 'value');
return this._value;
}
set value(newVal) {
if (hasChanged(toRaw(newVal), this._rawValue)) {
this._rawValue = newVal;
this._value = this._shallow ? newVal : convert(newVal);
trigger(toRaw(this), "set" /* SET */, 'value', newVal);
}
}
}
I'm not sure about it, maybe this error is related to ES version?
if so, where should I configure to get things right?
The bug is now fixed in Vue 3.1.4, so just install the newer version of vue in your project:
npm uninstall vue
npm i -S vue@3.1.4
This is a known issue with Vue CLI 4.5.13, which installs Vue 3.1.3. A few workarounds are available.
@vue/reactivity// vue.config.js
module.exports = {
transpileDependencies: ['@vue/reactivity']
}
npm uninstall vue
npm i -S vue@3.1.2
npm i -g @vue/cli@5
