我正在浏览HAPI js教程身份验证部分（http://hapijs.com/tutorials/auth?lang=en_US），这需要“bcrypt”。所以我做了“npm install bcrypt --save”。但是这给了像php这样的node-gyp错误。所以我按照这里给出的指示： https://github.com/nodejs/node-gyp#installation
我甚至做过：npm install --global --production windows-build-tools
但是现在它正在抛出错误：
“CL.exe”退出，代码为-1073741511
我已安装了他们要求的所有内容，但它不允许安装bcrypt。我该怎么办？
简单的教程练习花了我2天的研究，没有任何解决方案。为什么在教程中使用这种依赖性驱动的包？
这是我正在进行npm install bcrypt的实际控制台日志：

错误代码-1073741511转换为0xC0000139，显然是“未找到DLL”。
这让我觉得你的C ++构建工具链有问题，这是构建bcrypt库的本机位所必需的。
我知道这并没有多大帮助，但它在我的机器上工作：

关于你的问题，
为什么在教程中使用这种依赖性驱动的包？
- 这就是Node.js / NPM世界的方式。很多小包装做了一件事（据说做得很好，但情况并非总是这样）......
