node.js - 如何在 Windows 7 上加密 "npm install"

Question

我已经安装了 node.js v6.9.1 和 npm 版本 4.1.2，并且我已经在一些项目中使用了这个组合

现在我想在我的项目中使用bcrypt npm包，但是安装失败很惨

npm install bcrypt --save

我也试过用管理员权限运行这个命令，但没有成功

这是我得到的错误

问题似乎是 npm 找不到预构建的二进制文件，因此它尝试使用 python(我似乎没有)编译源代码。

我需要为此安装 python 吗？如果是，你能指出我正确的方向吗？真的没有 bcrypt 的预构建版本吗？

编辑:安装 Python 2.7 后，错误发生变化...似乎它试图使用 MSBuild 来编译一些 C++ 代码。

Answer 1

我建议你使用 bcrypt-nodejs:

https://www.npmjs.com/package/bcrypt-nodejs

它提供几乎相同的功能且易于使用。

原始答案:

您可以尝试以下操作吗:

1. 安装 Python ( http://www.python.org/download/releases/2.7.5/ )
2. 安装 Visual Studio 2012/13 Express(或其他)
3. 安装 Windows SDK(适用于 Windows 7/8)
4. 安装 Win64 OpenSSL v1.0.1g
5. 以管理员身份打开“VS2012 开发人员命令提示符”并测试安装

然后:

• npm install node-gyp -g
• npm install bcrypt -g
