Question

我目前在安装grunt命令行界面时遇到问题，当我尝试使用教程网站上的说明安装它时，我在日志中遇到了很多错误。我刚从我从他们网站上下载的软件包中添加了node.js.任何帮助将不胜感激？

我使用了以下命令，详细说明了根WordPress说明页面

npm install -g grunt-cli

并且返回了此错误消息

Answer 1

运行sudo npm install -g grunt-cli在全局安装时需要sudo权限，或者删除-g开关。

Answer 2

尽量避免使用npm sudo，可能会出现其他权限错误。这是我在使用sudo安装npm后所做的：

卸载NPM：sudo npm uninstall npm -g

安装NVM以便我可以在不需要sudo的情况下安装npm（类似于RVM），请参阅：https://github.com/creationix/nvm#installation

安装最新的npm：nvm install stable

清除缓存npm cache clear

然后一切正常
