typescript - 如何将角度 7 降级为角度 6

Question

我尝试通过运行以下 npm 命令将 angular 7 降级到 angular 6:

npm uninstall -g angular-cli
npm cache clean
npm install -g angular-cli@6.1.1

但是 angular/cli 7 version 仍然显示在我的 package.json 文件中。我需要帮助将 angular7 降级为 angular6。

Answer 1

您需要在您的 package.json 中为(至少)这个包设置版本号

"@angular/animations": "^7.0.0",
"@angular/cdk": "7.3.3",
"@angular/common": "^7.0.0",
"@angular/compiler": "7.2.6",
"@angular/core": "7.2.6",
"@angular/forms": "^7.0.0",
"@angular/http": "^7.0.0",
"@angular/material": "7.3.3",
"@angular/material-moment-adapter": "^7.3.3",
"@angular/platform-browser": "^7.0.0",
"@angular/platform-browser-dynamic": "^7.0.0",
"@angular/router": "^7.0.0",
"rxjs": "6.4.0",

以及开发依赖

"@angular/compiler-cli": "^7.2.6",
"@angular-devkit/build-angular": "0.13.3",
"typescript": "3.2.4",
"@angular/cli": "~7.3.3",

还要确保根据 Angular 的版本降级每个需要降级的库。检查第 1 步后的错误消息...

一旦你改变了它，运行

rm -rf node_modules

从项目的根文件夹中删除所有包

然后运行

npm i 

你应该可以开始了
