在Windows机器上安装bcrypt-nodejs时出现问题

Question

我在Windows机器上安装bcrypt-nodejs时遇到一些问题，而不是bcrypt，而bcrypt-nodejs是一个不同的依赖项。

在做npm install bcrypt-node.js后，我在命令行中得到了下面的输出

    C:\web_dev_root_folder\facerecognitionbrain>npm install bcrypt-nodejs
npm WARN [email protected] requires a peer of typescript@* but none is installed. You must install peer dependencies yourself.

当我继续尝试通过做npm start来运行我的脚本时，我得到：

任何解决方案将不胜感激。

你在错误的目录中运行你的npm install了吗？

看起来你在npm install做了C:\web_dev_root_folder\facerecognitionbrain，但是你需要它在C:\web_dev_root_folder\facerecognitionbrain-api\server.js中，它位于不同的目录中。
