我已经在我的node.js项目中安装了加密模块(npm install crypto)，但是当我启动我的应用程序时，我得到了这个错误：

Error: Cannot find package main file for package: /opt/PropertyFinder/node_modules/crypto

什么意思？我在哪里可以找到这个包的主文件？

node.js

cryptography

node-modules

也许您打算使用Node.js的内置crypto模块。

如果是这样的话，您不需要通过npm安装它，并且应该能够简单地在您的代码中使用require('crypto')。

(首先使用npm uninstall crypto删除“重复项”。)

错误是说该项目没有包含入口脚本。一般情况下，它也没有index.js or another "main" script specified来支持包的需求。

var crypto = require('/opt/PropertyFinder/node_modules/crypto');

它只包含两个松散的模块，md5.js和sha1.js，您必须分别需要它们：

var md5 = require('/opt/PropertyFinder/node_modules/crypto/md5');
var sha1 = require('/opt/PropertyFinder/node_modules/crypto/sha1');
