NPM不能在Windows上安装“松露”
问题描述:
我想用npm安装“松露”,但我不熟悉NodeJS,不能弄清楚为什么npm不会安装它。我尝试npm install -g truffle
在PowerShell中具有管理员权限后输出的几行,我得到错误信息块:NPM不能在Windows上安装“松露”
gyp ERR! build error

再经过很多很多的黄线,我终于得到这个:

后没有其他事情发生,过了一段时间它就结束了。在我目前所在的目录中没有文件(除单个日志文件外),cmd/powershell也找不到关键字“松露”。
正如我所说我以前从未与NodeJS合作过,也不知道这一切意味着什么。我能做些什么来让松露运行?
答
您的安装未通过node-gyp rebuild
。 node-gyp repo上列出了解决此问题的方法。最快的是:
“选项1:使用来自升级的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。这将正确安装Python和Visual Studio。
此外,您正在使用节点4.5。推荐版本为5+,根据Truffle Docs
