The easy solution is just switch from the "bcrypt" npm module to bycryptjsor bcrypt-nodejs. It's the exact same API, but pure JS so no native add-ons to deal with.
简单的解决方案是从“bcrypt”npm 模块切换到bycryptjsor bcrypt-nodejs。它是完全相同的 API，但是是纯 JS，因此无需处理本机附加组件。
npm install --save bcryptjs && npm uninstall --save bcrypt
Then change your requirecalls to "bcryptjs", but all your code otherwise can be unchanged.
然后将您的require调用更改为“bcryptjs”，但您的所有代码都可以保持不变。
Long term, I suspect at the moment bcrypt may not be ready for node v0.12.0 yet, but if not it will eventually be updated and ready.
从长远来看，我怀疑目前 bcrypt 可能还没有为节点 v0.12.0 做好准备，但如果没有，它最终会被更新并准备好。

for windows install the following module
对于 Windows 安装以下模块

npm install --g --production windows-build-tools
then try to install
然后尝试安装
npm install bcrypt

On this command:
在这个命令上：
npm install --g --production windows-build-tools
You may have to run this in Powershell as administrator on your Windows machine.
您可能必须在 Windows 计算机上以管理员身份在 Powershell 中运行它。
You do that by right-clicking on Powershell and select "Run As Administrator"
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

I just ran the following then tried the install and it worked:
我只是运行以下然后尝试安装，它工作：

The accepted solution won't work in 2020, Because bcryptjs is deprecated and no longer maintained because js version was much slower than python and c++ version.
接受的解决方案在 2020 年将不起作用，因为 bcryptjs 已弃用且不再维护，因为 js 版本比 python 和 c++ 版本慢得多。
? npm install --save bcryptjs && npm uninstall --save bcrypt
Now actually working solution are command below, but they can also have problem.
现在实际工作的解决方案是下面的命令，但它们也可能有问题。
?? npm install -g node-gyp
? npm install --g --production windows-build-tools
In Windows the second command will try to install visual studio along with python and hence the problem arises. because we why would we want to install Visual studio and it take a lot of time. and it also hinders the installation of python. And if you forget to run those command as Administrator then they will get installed at C:\Users\User.windows-build-tools which further will not work because node will search for python in C:\ or C:\Program Files\ . Hence this commands in some case increase your complications.
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。因为我们为什么要安装 Visual Studio 并且需要很多时间。并且它也阻碍了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，这将进一步不起作用，因为节点将在 C:\ 或 C:\Program Files\ 中搜索 python . 因此，此命令在某些情况下会增加您的复杂性。
So the best idea for you is to ??install python manually for All Users And It is not necessary to add python to environment path. And run only the first command i.e
所以对你来说最好的主意是为所有用户手动安装 python 并且没有必要将 python 添加到环境路径。并且只运行第一个命令即
?? npm install -g node-gyp
Now you are ready to install bcrypt
现在您已准备好安装 bcrypt

On Mac OS, after a Xcode update, running sudo gccand accepting Xcode's new license solved the problem!

I was facing the same issue on the server side( aws ubuntu 16.04).
我在服务器端（aws ubuntu 16.04）面临同样的问题。
I tried deleting node_module/bcrypt by sudo rm -rf node_module/bcryptmultiple times and reinstalled it again and again by various ways but still facing the same issue.
我尝试多次删除 node_module/bcryptsudo rm -rf node_module/bcrypt并通过各种方式一次又一次地重新安装它，但仍然面临同样的问题。
I checked node version with nvm and it was also showing stable (v10.11.0).
我用 nvm 检查了节点版本，它也显示稳定（v10.11.0）。
Finally, I tried.
最后，我试过了。
sudo npm cache clean -f
sudo npm install -g n
sudo n stable
and it worked for me.
