Vue-Cli整合Echart

一、创建Vue-Cli项目

npm下载缓慢解决方法

1、创建并运行Vue Cli hello-world项目

先下载node和npm，并分别使用node -v和npm -v查看相应版本。
安装vue-cli后，通过vue —version查看vue-cli版本
创建一个新项目（创建时可以选择是Vue3或者Vue2）：vue create hello-world
运行项目：cd hello-world后，npm run serve启动前端服务，通过http://localhost:8080/访问首页。

基于hello-world项目学习Vue-Cli 参考Vue-Cli官方教程

2、运行vue-element-admin项目

在运行[https://github.com/PanJiaChen/vue-element-admin项目时（更多使用参考vue-element-admin 中文文档），命令如下
```
# clone the project
git clone https://github.com/PanJiaChen/vue-element-admin.git

# enter the project directory
cd vue-element-admin

# install dependency
npm install

# develop
npm run dev
```
vue-element-admin对于新手并不是很友好，作者建议先通过‣项目练手。

vue-element-admin在安装第三方依赖时可能会存在如下问题：
- 第三方安装包在安装时发生冲突，解决方法参考Unable to resolve dependency tree error when installing npm packages
- npm安装时无法访问github，解决方法参考npm安装依赖超时
- 在执行npm install可能会出现如下问题：A git connection error occurred
  
  参考了网上一些解决方法都无法得到解决，比如npm安装依赖超时，vue-element-admin 安装第三包（npm install）时报错，npm install 时报 npm ERR command git --no-replace-objects ls-remote ssh，npm ERR! Please make sure you have the correct access rights 依赖无法安装，Cannot Install NPM Package - Code 128 An unknown git error occurred。以下是无效的方法
```
git config --global http.sslverify "false"
git config --global url."https://".insteadOf git://
git config --global url."https://github.com/".insteadOf "ssh://git@github.com/"
git config --global url."https://hub.fastgit.xyz/".insteadOf "ssh://git@github.com/"
npm config set legacy-peer-deps true
```
  解决方法：
  - 修改package.json，参考https://github.com/PanJiaChen/vue-element-admin/issues/4075；
```
1.克隆以后 删除package.json中tui-editor:1.3.3

2.\src\components\MarkdownEditor\index.vue文件，将全部import换成下面几个
import 'codemirror/lib/codemirror.css'
import '@toast-ui/editor/dist/toastui-editor.css'
import Editor from '@toast-ui/vue-editor'
import defaultOptions from './default-options'
并将该文件下的getValue和setValue分别换成getMarkdown和setMarkdown

3.单独安装tui-editor
npm install --save @toast-ui/vue-editor

4.安装其他依赖
npm i

5.跑起来
npm run dev
```
    但是在单独执行tui-editor也报了这个错
  - 然后添加代理，这里我买的加速器，代理端口是10810，参考https://github.com/PanJiaChen/vue-element-admin/issues/3859；
```
git config --global http.proxy http://127.0.0.1:10810
git config --global https.proxy https://127.0.0.1:10810
```
    安装成功
  - 在执行npm run dev可能会出现依赖未找到的情况
    
    原因是有个vue文件中引用了package.json没有添加的依赖，导致报错，根据提示进行npm install即可。
- 在执行npm run dev时，可能会出现很多warning或者error
  
  这些错误是ESlint语法规范错误提示，即使报错了浏览器也可能正常显示页面。
  
  ESlint是一个代码检查工具，用来检查你的代码是否符合指定的规范
  - 行业推荐的规范；在创建项目时，我们使用的是 JavaScript Standard Style 代码风格的规则
  - 自定义的规范。你和你的团队可以自行约定一套规范
    
    ESlint的好处是**在多人协作时，代码风格可以统一。参考ESLint-的基本介绍，✖ 48 problems (48 errors, 0 warnings) 45 errors and 0 warnings potentially fixable with the --fix]([✖ 48 problems (48 errors, 0 warnings) 45 errors and 0 warnings potentially fixable with the –fix_4 problems (4 errors, 0 warnings) 4 errors and 0 w_object not found的博客-CSDN博客)

【Vue】Vue-Cli整合Echart,# vue,前端,vue.js,前端,javascript

2、使用VueCli + echarts实现K线图绘制

这里对上面纯JS的echarts代码进行修改

之前的splitData和calculateMA方法写在Vue的methods中
之前的option变量定义在initData方法中（通过mounted函数来实现初始化，而且其中一些变量要加this，比如this.calculateMA，this.upColor，this.klineData.categoryData，否则浏览器页面会报错），并通过echarts的setOption来设置该变量，完成图表样式、标题等的设置操作（通过echarts.init()来初始化echarts实例，文档参考https://echarts.apache.org/zh/api.html#echarts.init）。

将之前的SZlineData数据变量定义在initData方法中（也可以是文件引入或获取接口数据），并调用splitData完成数据的处理操作。
