| 错误码 | 信息 |
|---|---|
| 0 | Illegal comment. |
| 1 | CDATA section is allowed only in XML context. |
| 2 | Duplicate attribute. |
| 3 | End tag cannot have attributes. |
| 4 | Illegal '/' in tags. |
| 5 | Unexpected EOF in tag. |
| 6 | Unexpected EOF in CDATA section. |
| 7 | Unexpected EOF in comment. |
| 8 | Unexpected EOF in script. |
| 9 | Unexpected EOF in tag. |
| 10 | Incorrectly closed comment. |
| 11 | Incorrectly opened comment. |
| 12 | Illegal tag name. Use '<' to print '<'. |
| 13 | Attribute value was expected. |
| 14 | End tag name was expected. |
| 15 | Whitespace was expected. |
| 16 | Unexpected '<!--' in comment. |
| 17 | Attribute name cannot contain U 0022 ("), U 0027 ('), and U 003C (<). |
| 18 | Unquoted attribute value cannot contain U 0022 ("), U 0027 ('), U 003C (<), U 003D (=), and U 0060 (`). |
| 19 | Attribute name cannot start with '='. |
| 20 | Unexpected null character. |
| 21 | '<?' is allowed only in XML context. |
| 22 | Illegal '/' in tags. |
| 23 | Invalid end tag. |
| 24 | Element is missing end tag. |
| 25 | Interpolation end sign was not found. |
| 26 | Legal directive name was expected. |
| 27 | End bracket for dynamic directive argument was not found. Note that dynamic directive argument cannot contain spaces. |
| 28 | v-if/v-else-if is missing expression. |
| 29 | v-if/else branches must use unique keys. |
| 30 | v-else/v-else-if has no adjacent v-if or v-else-if. |
| 31 | v-for is missing expression. |
| 32 | v-for has invalid expression. |
| 33 | <template v-for> key should be placed on the <template> tag. |
| 34 | v-bind is missing expression. |
| 35 | v-on is missing expression. |
| 36 | Unexpected custom directive on <slot> outlet. |
| 37 | Mixed v-slot usage on both the component and nested <template>. When there are multiple named slots, all slots should use <template> syntax to avoid scope ambiguity. |
| 38 | Duplicate slot names found. |
| 39 | Extraneous children found when component already has explicitly named default slot. These children will be ignored. |
| 40 | v-slot can only be used on components or <template> tags. |
| 41 | v-model is missing expression. |
| 42 | v-model value must be a valid JavaScript member expression. |
| 43 | v-model cannot be used on v-for or v-slot scope variables because they are not writable. |
| 44 | v-model cannot be used on a prop, because local prop bindings are not writable. Use a v-bind binding combined with a v-on listener that emits update:x event instead. |
| 45 | Error parsing JavaScript expression: |
| 46 | <KeepAlive> expects exactly one child component. |
| 47 | "prefixIdentifiers" option is not supported in this build of compiler. |
| 48 | ES module mode is not supported in this build of compiler. |
| 49 | "cacheHandlers" option is only supported when the "prefixIdentifiers" option is enabled. |
| 50 | "scopeId" option is only supported in module mode. |
| 51 | @vnode-* hooks in templates are no longer supported. Use the vue: prefix instead. For example, @vnode-mounted should be changed to @vue:mounted. @vnode-* hooks support has been removed in 3.4. |
| 52 | v-bind with same-name shorthand only allows static argument. |
| 53 | v-html is missing expression. |
| 54 | v-html will override element children. |
| 55 | v-text is missing expression. |
| 56 | v-text will override element children. |
| 57 | v-model can only be used on <input>, <textarea> and <select> elements. |
| 58 | v-model argument is not supported on plain elements. |
| 59 | v-model cannot be used on file inputs since they are read-only. Use a v-on:change listener instead. |
| 60 | Unnecessary value binding used alongside v-model. It will interfere with v-model's behavior. |
| 61 | v-show is missing expression. |
| 62 | <Transition> expects exactly one child element or component. |
| 63 | Tags with side effect (<script> and <style>) are ignored in client component templates. |
