Question

我正在尝试安装＆＃34;松露＆＃34;与npm，但我不熟悉NodeJS并且无法弄清楚为什么npm不会安装它。我在Powershell中使用管理员权限尝试npm install -g truffle，在几行输出后，我收到了以下错误消息：

 gyp ERR! build error
 gyp ERR! stack Error: `C:\Program Files (x86)\MSBuild\14.0\bin\msbuild.exe` failed with exit code: 1
 gyp ERR! stack     at ChildProcess.onExit (F:\nodeJS\node_modules\npm\node_modules\node-gyp\lib\build.js:276:23)

 gyp ERR! node -v v4.5.0
 gyp ERR! node-gyp -v v3.4.0
 gyp ERR! not ok\

然后经过许多黄线后我终于得到了这个：

 npm ERR! Windows_NT 10.0.14393
 npm ERR! argv "F:\\nodeJS\\node.exe" "F:\\nodeJS\\node_modules\\npm\\bin\\npm-cli.js" "install" "-g" "truffle"

 npm ERR!     npm owner ls scrypt
 npm ERR! There is likely additional logging output above.

 npm ERR! Please include the following file with any support request:

之后没有其他事情发生，过了一会儿就会终止。我目前所在的目录中没有文件（单个日志文件除外）和关键字＆＃34; truffle＆＃34; cmd / powershell也找不到。

正如我所说，我以前从未使用过NodeJS，也不知道这一切意味着什么。我能做些什么来开松露？

您的安装在node-gyp rebuild失败。 node-gyp repo列出了此问题的解决方案。最快的是：

＆＃34;选项1：使用来自提升的PowerShell或CMD.exe（以管理员身份运行）的npm install --global --production windows-build-tools使用Microsoft的windows-build-tools安装所有必需的工具和配置。＆＃ 34;这将正确安装Python和Visual Studio。

此外，您正在使用Node 4.5。根据{{3}}
