一、 用git命令拉取分支时的报错行代码段

Component is not found in path "pages/index/miniprogram_npm/vant-weapp/action-sheet" (using by "pages/index/index");onAppRoute

其中最主要的问题是错误的引入了npm包，并且导致路径有可能出错。

二、 解决方案

1、确认是否安装vant-weapp，安装步骤如下：

1.1执行npm init

1.2回车到结束

1.3 npm i vant-weapp -S --production

1.4工具->生成npm，这时你的文件目录会生成miniprogram_npm中文件为你所内置的Npm包

2.项目详情->使用npm（如果报错继续执行第1.4步，建造npm）

3.查看工具->项目详情-> ES6转ES5是否√选，如果没有，请点击。

总结：一般来讲按流程走一遍就可以了，不过不排除意外,这个方法也是我在网上搜到的，这算是做了个知识的储备吧！
