javascript - 使用 bcrypt 的纯 JavaScript 实现

Question

您好，我正在使用 Meteor js，这很棒，但我在控制台上收到此消息。

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.

我全局安装了node-gyp，从包文件中删除bcrypt并运行

meteor npm install --save bcrypt

得到这个错误

不知道下一步该做什么，我真的对 meteor 很陌生。我在 Windows 10 上使用 shell。 Node v4.6.0 任何帮助都会很棒。

您需要安装适当的构建环境来编译 Node 插件(例如bcrypt)。这意味着安装 Python 2.7.x 和某种工具链。

您可以尝试windows-build-tools模块将尝试通过 npm 安装 Python 和最小编译器环境(或者您可以从 here 手动安装最小编译器环境)，否则对于工具链部分，始终有 Visual C++ Express/Community(桌面版本)。
