解决方法
npm install @angular/common@latest @angular/compiler@latest @angular/compiler-cli@latest @angular/core@latest @angular/forms@latest @angular/http@latest @angular/platform-browser@latest @angular/platform-browser-dynamic@latest @angular/platform-server@latest @angular/router@latest @angular/animations@latest typescript@latest --save
其实在升级过程中除此之外还遇到好多问题，最后我还是卸载了以钱的angular/cli，重新装了6.0版本的cli然后来重新构建项目用到的依赖。
在我引入UI框架ng-zorro-antd时候又报一堆错误：
错误2
ERROR in ./node_modules/ng-zorro-antd/src/ng-zorro-antd.less (./node_modules/raw-loader!./node_modules/postcss-loader/lib??embedded!./node_modules/less-loader/dist/cjs.js??ref--15-3!./node_modules/ng-zorro-antd/src/ng-zorro-antd.less)
Module build failed:
// https://github.com/ant-design/ant-motion/issues/44
.bezierEasingMixin();
^
Inline JavaScript is not enabled. Is it set in your options?
in E:\projects\my-project\node_modules\ng-zorro-antd\src\style\color\bezierEasing.less (line 110, column 0)
解决方法
由于@angular/cli 6.0版本构建时下载的是less3.0，但是less3.0暂不支持javascriptEnabled 选项，所以你要降级到less2.7版本
错误3

解决方法
应该运行 npm install --save [email protected] 详见 https://github.com/NG-ZORRO/ng-zorro-antd/issues/1442
rxjs-compat 用于兼容 rxjs 5.x

这个错误是在下载angular/cli时出现的
解决方法是
以管理员身份运行还是不可以解决，最后加了参数就OK了
npm install -g @angular/cli -no-optiona
最后给同样在升级过程中遇到问题的你一条建议，一定要在升级某个技术版本的时候，去关注该技术的github。
