我更新了我的角度cli版本，现在显示角度：5.2.0

我在angular4中构建了完整的代码。你能帮助我降级我的angularcli版本（特定版本）的步骤，以便我有angular4。这是我目前的配置：

Angular CLI: 1.6.4
Node: 9.2.1
OS: win32 x64
Angular: 5.2.0
@angular/cli: 1.6.4
@angular-devkit/build-optimizer: 0.0.38
@angular-devkit/core: 0.0.25
@angular-devkit/schematics: 0.0.48
@ngtools/json-schema: 1.1.0
@ngtools/webpack: 1.9.4
@schematics/angular: 0.1.13
@schematics/schematics: 0.0.13
typescript: 2.4.2
webpack: 3.10.0

全局

Angular CLI: 1.6.3
Node: 9.2.1
OS: win32 x64
Angular:
...

我尝试过以下命令，但没有运气

npm uninstall -g angular-cli
npm cache clean
npm install -g angular-cli@1.0.0-beta.14

因为角度包名称已更改：

npm uninstall -g @angular/cli
npm cache clean
npm install -g  @angular/cli@latest

另请注意，@angular/cli版本和角度版本是互斥的。

如果您只想降级项目的角度版本，请更改angular中的package.json版本。
