Question

Angular 安装失败并出现以下错误，并且未安装 Angular。

D:\software\node-v8.11.2-win-x64>npm install -g @angular/cli D:\软件\node-v8.11.2-win-x64\ng -> D:\eclipse\software\node-v8.11.2-win-x64\node_modules@angular\cli\bin\ng

@angular/cli@6.0.8 安装后 D:\eclipse\software\node-v8.11.2-win-x64\node_modules@angular\cli 节点 ./bin/ng-update-message.js

'node' 不是内部或外部命令，可操作 程序或批处理文件。 npm WARN 可选跳过可选依赖： fsevents@1.2.4 (node_modules@angular\cli\node_modules\fsevents): npm 警告 notsup 跳过可选依赖：不支持的平台 fsevents@1.2.4: 想要 {"os":"darwin","arch":"any"}（当前： {"os":"win32","arch":"x64"})

npm 错误！代码 ELIFECYCLE npm 错误！ errno 1 npm 错误！ @angular/cli@6.0.8 安装后：节点 ./bin/ng-update-message.js npm ERR！退出状态 1 npm 错误！ npm 错误！ @angular/cli@6.0.8 安装后脚本失败。 npm 错误！这可能不是 npm 的问题。有可能 上面的附加日志输出。
