目前我正在做一个项目，我需要访问各种不同的库，但问题是我非常卡住了。我的程序是一个基于网络的应用程序，使用以太坊区块链（ganache，truffle，metamask）。例如，我试图通过一个JavaScript文件访问库web3-eth-accounts，我在我的网站上按下一个按钮就可以访问，但所有发生的是这样的：
Uncaught Error: Cannot find module 'web3-eth-accounts'
at o (web3.min.js:1)
at o (web3.min.js:1)
at Object.init (Test.js:4)
at HTMLButtonElement.onclick (statePrototype.html:26)JavaScript语言：
Test = {
init : function () {
var Web3EthAccounts = require('web3-eth-accounts');
var account = new Web3EthAccounts('ws://localhost:7545');
}
}包括web3-eth-accounts在内的所有库都在node-modules文件夹中。
