使用bcrypt的纯JavaScript实现

Question

你好我正在使用流星js，这是伟大的，但我在我的控制台上得到这个消息。

W20161001-16:02:18.321(1)? (STDERR) Note: you are using a pure-JavaScript implementation of bcrypt. 
W20161001-16:02:18.322(1)? (STDERR) While this implementation will work correctly, it is known to be 
W20161001-16:02:18.322(1)? (STDERR) approximately three times slower than the native implementation. 
W20161001-16:02:18.322(1)? (STDERR) In order to use the native implementation instead, run 
W20161001-16:02:18.323(1)? (STDERR) 
W20161001-16:02:18.323(1)? (STDERR) meteor npm install --save bcrypt 
W20161001-16:02:18.323(1)? (STDERR) 
W20161001-16:02:18.323(1)? (STDERR) in the root directory of your application. 

我有节点GYP全球安装，从包文件中删除bcrypt和运行

meteor npm install --save bcrypt

得到这个错误

不知道下一步该怎么做我真的很流星真的很新鲜。我在使用shell的Windows 10上。节点v4.6.0任何帮助都会很棒。

您需要安装合适的编译环境来编译节点插件（如bcrypt）。这意味着安装Python 2.7.x和某种工具链。

你可以尝试windows-build-tools模块将尝试安装Python和通过NPM最小编译环境（或者你可以从here手动安装最小编译环境），否则只是工具链的部分总是存在的Visual C++速成/社区（桌面版）。
