如何在Windows 7上进行“npm install bcrypt”

node.jswindowsbcrypt
9

我已经安装了node.js v6.9.1和npm版本4.1.2，并且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，但是安装失败了。

npm install bcrypt --save

我也尝试以管理员权限运行此命令，但结果还是失败了。

这是我得到的错误信息。

问题似乎在于npm找不到预先构建的二进制文件，因此它尝试使用Python编译源代码（而我好像没有Python）。
我需要安装Python吗？如果是，你能告诉我正确的安装方法吗？bcrypt没有预先构建的版本是真的吗？
编辑：安装Python 2.7后，错误信息发生了变化...似乎它尝试使用MSBuild来编译一些C++代码。

“Python 2.x”被列为npm上的明确依赖项，因此我怀疑您无法避免使用它。 - Aleksey Bilogur
奇怪的是，在安装了Python 2.7之后，错误发生了变化。请参见最新编辑。 - devnull69

请参阅node-gyp文档以获取在Windows上的安装要求。 - dNitro

我建议您使用bcrypt-nodejs：

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

它提供了几乎相同的功能并易于使用。

原始回答：

您可以尝试以下操作：

  1. 安装Python（http://www.python.org/download/releases/2.7.5/）
  2. 安装Visual Studio 2012/13 Express（或其他版本）
  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的Developer Command Prompt”，然后测试安装

然后执行以下操作：

  • npm install node-gyp -g
  • npm install bcrypt -g
不行，结果相同。 - devnull69
@devnull69，你能否尝试一下我在最近的编辑中提到的事情？ - Pankaj kumar Panigrahi

bcrypt-nodejs是胜利者。 - devnull69
请参考@Whymarrh的回答。首先需要运行npm install --global --production windows-build-tools，然后再安装bcrypt。 - Conor Patrick

我遇到了同样或类似的错误。 在尝试安装bcrypt之前运行以下命令可以解决问题：

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

今天我在尝试在Windows 10桌面上安装bcrypt时遇到了同样的问题。原来bcrypt支持Node的稳定版本，可以查看文档以获取更多信息。
对我来说解决方案是：
  1. 将Node升级到稳定版本：我手动从Node网站下载并安装了Windows安装程序。
  2. 全局安装Windows构建工具：npm install --global --production windows-build-tools
  3. 最后执行npm install bcrypt --save
完成以上步骤后一切正常。
Node.js现在包含了Windows的构建工具。你可能不再需要这个工具了。详情请见https://github.com/felixrieseberg/windows-build-tools。https://www.npmjs.com/package/windows-build-tools - Artyom Ionash

我也遇到了这个错误。

我使用以下命令重新安装了node-gyp npm install node-gyp -g 然后我重新安装了bcrypt npm install bcrypt 最终成功了

在开发 Node API 项目时，
解决方案：

rm -rf node_modules/bcrypt

npm install node-gyp -g

npm install bcrypt@[版本号] -g

在 Windows 10 上对我有效。
