 ## 工程编译：
 Horizon采用monorepo方式管理项目，意思是在版本控制系统的单个代码库里包含了许多项目的代码
 
-monorepo工具采用yarn
-### yarn配置
-1. yarn1（推荐）
-``` shell
-// 先安装yarn
-npm i yarn -g
-```
-在 `C:\Users\[工号]\.yarnrc`无相应文件需要新建
-
-加入yarn配置：
-```shell
-registry "http://szxy1.artifactory.cd-cloud-artifact.tools.huawei.com/artifactory/api/npm/sz-npm-public"
-no-proxy .huawei.com
-lastUpdateCheck 1646381423295
-strict-ssl false
-```
-2. yarn2
-
-由于yarn2+有不兼容更新，安装方式依赖node 16+的corepack功能，安装参考 [yarn官网](https://yarnpkg.com/getting-started/install)
-在 `C:\Users\[工号]\.yarnrc.yml`加入yarn配置，无相应文件需要新建
-
-加入yarn配置：
-```shell
-npmRegistryServer "http://szxy1.artifactory.cd-cloud-artifact.tools.huawei.com/artifactory/api/npm/sz-npm-public"
-```
-注意：yarn2配置文件和字段都存在大量不兼容，参考[详细配置](https://yarnpkg.com/configuration/yarnrc#npmRegistryServer)
+monorepo工具采用npm workspaces **（npm版本需要大于7.x）**
 ### 工程命令
 #### 安装
 ```shell
-yarn
+npm install
 ```
-> 需要使用yarn安装，monorepo的依赖才能正确安装到node_modules
+> 需要使用npm7.x以后版本安装，monorepo的依赖才能正确安装到node_modules
 #### 打包
 ```shell
-yarn run build
+npm run build
 ```
 #### 全局单元测试
 ```shell
-yarn run test
+npm run test
 ```
