Question

我已经将node.js v6.9.1和npm版本4.1.2一起安装了，并且我已经将这个组合用于某些项目

现在我想在我的项目中使用bcrypt npm包，但是安装失败了

npm install bcrypt --save

我还试图用admin权限运行此命令，但无济于事

这是我得到的错误

问题似乎是npm无法找到预先构建的二进制文件，所以它尝试使用python编译源代码（我似乎没有）。

我需要为此安装python吗？如果是的话，你能指出我正确的方向吗？是不是没有预先构建的bcrypt版本？

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

Answer 1

我建议你使用bcrypt-nodejs：

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

它提供了几乎相同的功能，易于使用。

原始答案：

您可以尝试以下方法：

安装Python（http://www.python.org/download/releases/2.7.5/）
安装Visual Studio 2012/13 Express（或其他）
安装Windows SDK（适用于Windows 7/8）
安装Win64 OpenSSL v1.0.1g
打开＆＃34;开发人员命令提示符VS2012＆＃34;作为管理员和测试安装

然后：

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

Answer 2

我遇到过相同或至少类似的错误。在尝试安装bcrypt之前运行以下内容为我解决了这个问题：

npm install --global --production windows-build-tools

Answer 3

我今天在尝试在Windows 10桌面上安装bcrypt时也遇到了同样的问题。事实证明，bcrypt支持稳定版本的node更好地检查了docs

对我来说，解决方案是：

将节点升级到稳定版本：我从Node网站手动下载并安装Windows安装程序。
全局安装Windows构建工具：npm install --global --production windows-build-tools
最后npm install bcrypt --save

此后一切正常。

Answer 4

在处理节点API项目时。

解决方案

rm -rf node_modules / bcrypt

npm install node-gyp -g

npm install bcrypt @ [VERSION] -g

在第10窗口上对我有用。

Answer 5

我也遇到了这个错误。

我使用此命令npm install node-gyp -g重新安装node-gyp 之后，我使用npm install bcrypt重新安装bccrypt 终于可以了

如何＆＃34; npm安装＆＃34; Windows 7上的bcrypt
