一、创建Vue-Cli项目
参考资料
- 从零搭建vue2项目
- Vue-cli官网
- 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 devvue-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://[email protected]/" git config --global url."https://hub.fastgit.xyz/".insteadOf "ssh://[email protected]/" 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)

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。<!-- 参考 https://blog.csdn.net/m0_46309087/article/details/127201213 --> <template> <div class="echart" id="chart-container" style="width:100%; height: 400px;"></div> </template> <script> import * as echarts from "echarts"; // console.log(SZlineData); export default { data() { return { upcolor: "#FF0000", //增长颜色 upBorderColor: "#8A0000", downColor: "#008000", // 下跌颜色 downBorderColor: "#008F28", klineData: [] //k线图数据 };
