vue-element-admin的安装以及安装报错处理

一、vue-element-admin git地址

https://github.com/PanJiaChen/vue-element-admin

二、分支

　　master：主分支，（纯英文）

　　il8n：中英文切换分支

三、npm install 安装报错原因： tui-editor 已更新，故造成错误，修改如下

四、安装报错处理

1、修改package.json文件

　　　将 "tui-editor": "1.3.3" 替换成 "@toast-ui/editor": "^3.1.3"

2、找到 src/components/MarkdownEditor/index.vue 文件修改代码

（1）将 import 'tui-editor/dist/tui-editor.css' 替换成 import '@toast-ui/editor/dist/toastui-editor.css'

（2）将 import Editor from 'tui-editor' 替换成 import Editor from '@toast-ui/editor'

（3）去掉 import 'tui-editor/dist/tui-editor-contents.css'

（4）将所有 editor.getValue 替换成 editor.getMarkdown

（5）将所有 editor.setValue 替换成 editor.setMarkdown

（6）将 editor.getHtml 替换成 editor.getHTML

修改完如下：

<template>
  <div :id="id" />
</template>

<script>
// deps for editor
import 'codemirror/lib/codemirror.css' // codemirror
import '@toast-ui/editor/dist/toastui-editor.css' // editor style

import Editor from '@toast-ui/editor'
import defaultOptions from './default-options'

export default {
  name: 'MarkdownEditor',
  props: {
    value: {
      type: String,
      default: ''
    },
    id: {
      type: String,
      required: false,
      default() {
        return 'markdown-editor-' + +new Date() + ((Math.random() * 1000).toFixed(0) + '')
      }
    },
    options: {
      type: Object,
      default() {
        return defaultOptions
      }
    },
    mode: {
      type: String,
      default: 'markdown'
    },
    height: {
      type: String,
      required: false,
      default: '300px'
    },
    language: {
      type: String,
      required: false,
      default: 'en_US' // https://github.com/nhnent/tui.editor/tree/master/src/js/langs
    }
  },
  data() {
    return {
      editor: null
    }
  },
  computed: {
    editorOptions() {
      const options = Object.assign({}, defaultOptions, this.options)
      options.initialEditType = this.mode
      options.height = this.height
      options.language = this.language
      return options
    }
  },
  watch: {
    value(newValue, preValue) {
      if (newValue !== preValue && newValue !== this.editor.getMarkdown()) {
        this.editor.setMarkdown(newValue)
      }
    },
    language(val) {
      this.destroyEditor()
      this.initEditor()
    },
    height(newValue) {
      this.editor.height(newValue)
    },
    mode(newValue) {
      this.editor.changeMode(newValue)
    }
  },
  mounted() {
    this.initEditor()
  },
  destroyed() {
    this.destroyEditor()
  },
  methods: {
    initEditor() {
      this.editor = new Editor({
        el: document.getElementById(this.id),
        ...this.editorOptions
      })
      if (this.value) {
        this.editor.setMarkdown(this.value)
      }
      this.editor.on('change', () => {
        this.$emit('input', this.editor.getMarkdown())
      })
      this.editor.addHook('addImageBlobHook', (file, cb) => {
        if (typeof this.$listeners.uploadImageEvent === 'function') {
          this.$emit('uploadImageEvent', file, cb)
        } else {
          const reader = new FileReader()
          reader.onload = ({ target }) => { cb(target.result || '') }
          reader.readAsDataURL(file)
        }
      })
    },
    destroyEditor() {
      if (!this.editor) return
      this.editor.off('change')
      this.editor.destroy()
    },
    setValue(value) {
      this.editor.setMarkdown(value)
    },
    getValue() {
      return this.editor.getMarkdown()
    },
    setHtml(value) {
      this.editor.setHTML(value)
    },
    getHtml() {
      return this.editor.getHTML()
    }
  }
}
</script>

（7）将同级 default-options.js修改如下

toolbarItems: [
  'heading','bold','italic','strike','divider',
  'hr','quote','divider',
  'ul','ol','task','indent','outdent','divider',
  'table','image','link','divider',
  'code','codeblock'
]

替换成

toolbarItems: [
  ['heading', 'bold', 'italic', 'strike'], 
  ['hr', 'quote'], 
  ['ul', 'ol', 'task', 'indent', 'outdent'],
  ['table', 'image', 'link'],
  ['code', 'codeblock']
]

（8）将 src/views/components-demo/markdown.vue 文件中
