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
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://[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)

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。
