Webpack 未找到模块：无法解析web3无法解析块菌合同

当我运行命令

npm run dev

时，它给了我这个错误，我多次尝试安装不同版本的

web3

和truffle contract，但每次都给我相同的错误

确切错误：

ERROR in ./app/javascripts/app.js
Module not found: Error: Can't resolve 'truffle-contract' in 'C:\Users\Siddharth\Desktop\SID\ALSC\PROJECT\asset-lending\app\javascripts'
 @ ./app/javascripts/app.js 6:1-55
 @ multi (webpack)-dev-server/client?http://localhost:8080 ./app/javascripts/app.js

npm install truffle contract解决了这两个错误，如果它不起作用，请尝试全局安装，在我的例子中，我是在本地安装的

我在本地和全局都尝试过，但仍然出现了相同的错误
