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.
