我已将加密模块 (npm install crypto) 安装到我的 node.js 项目中，但是当我启动我的应用程序时，出现此错误:
Error: Cannot find package main file for package: /opt/PropertyFinder/node_modules/crypto

这是什么意思？我在哪里可以找到该包的主文件？
最佳答案
也许您打算使用 Node.js 的内置 crypto模块。
如果是这样，您不需要通过 npm 安装它，并且应该能够简单地在代码中 require('crypto') 。
(首先使用npm uninstall crypto删除“重复项”。)
