ANGULAR 6.1 to 7 MIGRATION PROCEDURE 6.1至7的角度迁移程序
In order to upgrade properly from Angular 6.1 to angular 7, you have to follow the next steps: 为了从Angular 6.1正确升级到angular 7,您必须执行以下步骤:
WARNING: Please check if all your imported modules are compatible with angular 7, upgrade them if necessary.
警告:请检查所有导入的模块是否与angular 7兼容,如有必要,请升级它们。
Before upgrade to Angular 7: 升级到Angular 7之前:
Change the HttpModule import to HttpClientModule (import {HttpClientModule} from '@angular/common/http';) 将HttpModule导入更改为HttpClientModule(从'@ angular / common / http'导入{HttpClientModule};)
Change the Http imports (if you have any) to import {HttpClient} from '@angular/common/http'; 更改Http导入(如果有),以从'@ angular / common / http'导入{HttpClient};
Don´t forget to remove all JSON.parse(response), since you don´t need to do that anymore with HttpClient
不要忘了删除所有JSON.parse(response),因为您不再需要使用HttpClient来做到这一点。
If you are using RXjs, you have to remove RXjs 6 old dependencies. 如果使用的是RXjs,则必须删除RXjs 6的旧依赖性。 No worries, you can do that running the following scripts:
不用担心,您可以运行以下脚本来做到这一点:
npm install -g rxjs-tslint npm install -g rxjs-tslint
rxjs-5-to-6-migrate -p src/tsconfig.app.json rxjs-5-to-6-migrate -p src / tsconfig.app.json
You may have to update typescript in order to migrate rxjs successfully: npm i -g typescript
为了成功迁移rxjs,可能必须更新打字稿:npm i -g打字稿
If you use the Angular Service worker, migrate any versionedFiles to the files array. 如果使用Angular Service工作器,请将所有versionedFiles迁移到files数组。
Update angular cli to v7: 将angular cli更新到v7:
ng update @angular/cli ng update @ angular / cli
Update angular Core to v7: 将Angle Core更新到v7:
ng update @angular/core ng更新@ angular / core
Finally you have to upgrade Angular material: 最后,您必须升级Angular材质:
ng update @angular/material ng更新@ angular / material
ng-update也不适合我-我通过使用npm-check更新所有软件包并整理出手动后遇到的一些错误来解决该问题。
If you are looking like me for just updating your project to the latest these is what works form me since Angular 6: 如果您像我一样只是将项目更新为最新版本,那么从Angular 6开始,这些就是我的工作方式:
Open the console on your project folder:
If you type: ng update
then you will get the below message:打开项目文件夹上的控制台:
If you type: ng update
,则会收到以下消息:
We analyzed your package.json, there are some packages to update:
Name Version Command to update
--------------------------------------------------------------------------------
@angular/cli 7.0.7 -> 7.2.2 ng update @angular/cli
@angular/core 7.0.4 -> 7.2.1 ng update @angular/core
There might be additional packages that are outdated.
Run "ng update --all" to try to update all at the same time.
So I usually go straight and do:
因此,我通常会直接去做:
ng update --all
Finally you can check your new version:
最后,您可以检查新版本:
ng version
