Native WeChat applet error: [app.json file content error]app.json:[“usingComponents“][“van-image“]:“@vant/weapp/image/index“

After pulling the code from the warehouse, npm i starts the project and an error occurs, as shown in the figure:

Solution:

First npm i downloads the project dependencies. After the download is complete, go to the upper left cornerTools--Build npm to generate miniprogram_npm package

After seeing the generated miniprogram_npm package, directly delete the node_modules folder and recompile the project~

Note: If miniprogram_npm and node_modules are accidentally deleted later, or another plug-in is installed by executing npm install "插件" , as long as there is a corresponding plug-in package under dependencies in the package.json file, You can delete both miniprogram_npm and node_modules, then execute npm i, and finally build npm as above.
