Answer 1

简单的解决方案是从"bcrypt"npm模块切换到bycryptjs或bcrypt-nodejs.它是完全相同的API,但纯JS,因此没有处理的本机附加组件.

npm install --save bcryptjs && npm uninstall --save bcrypt

然后将您的require调用更改为"bcryptjs",但所有代码都可以保持不变.

从长远来看,我怀疑目前bcrypt还没有为节点v0.12.0做好准备,但如果没有,它最终会更新并准备就绪.

Answer 2

对于Windows安装以下模块

npm install -g node-gyp
npm install --g --production windows-build-tools

然后尝试安装

npm install bcrypt

Answer 3

在这个命令上:

npm install --g --production windows-build-tools

您可能必须在Windows计算机上以管理员身份在Powershell中运行它.

您可以通过右键单击Powershell并选择"以管理员身份运行"来执行此操作

Answer 4

升级到bcrypt@5.0.0

npm i bcrypt@5.0.0

我在这个较新版本的 bcrypt 上没有收到错误，旧版本给出了不同类型的错误，从无法安装 bcrypt 到打字稿类型错误

Answer 5

接受的解决方案有效，但 bcryptjs 比 python 和 C++ 版本慢。

如果你仍然想要 bcrypt 而不是 bcryptjs，工作解决方案是下面的命令，但它们也可能有自己的问题。

?? npm install -g node-gyp
? npm install --g --production windows-build-tools

在 Windows 中，第二个命令将尝试与 python 一起安装 Visual Studio，因此出现问题是因为 Visual Studio 安装需要很多时间。它还阻碍了python的安装。如果您忘记以管理员身份运行这些命令，那么它们将安装在 C:\Users\User.windows-build-tools 中，但仍然无法工作，因为 node 将在 C:\ 或 C:\Program Files 中搜索 python。因此，在某些情况下，这些命令可能会增加您的复杂性。

所以对你来说最好的主意是为所有用户手动安装 python。没有必要将 python 添加到环境路径中。

然后运行：

?? npm install -g node-gyp

现在您已准备好安装 bcrypt：

npm install bcrypt
