发现不兼容的对等依赖项 - 将 Angular 从 8 升级到 9 [英] Incompatible peer dependencies found - upgrading Angular from 8 to 9

问题描述

我是按照官方文档升级的.

I am following the official document to upgrade.

此步骤已完成，没有任何错误.

This step completed without any errors.

ng update @angular/core@8 @angular/cli@8

下一步失败.

ng update @angular/core @angular/cli

                  Package "@ngtools/webpack" has an incompatible peer dependency to "typescript" (requires ">=3.4 < 3.6", would install "3.7.5").
Incompatible peer dependencies found.
Peer dependency warnings when installing dependencies means that those dependencies might not work correctly together.
You can use the '--force' option to ignore incompatible peer dependencies and instead address these warnings later.

我检查了 node_modules 并安装了正确版本的 tslib.我手动添加了 tslib 条目并运行 npm install 以查看错误是否消失.

I checked the node_modules and the correct version of tslib is installed. I manually added the tslib entry and ran npm install to see if the error goes away.

我没有尝试使用 --force 选项.还有别的方法吗?

I haven't tried to use --force option. Is there another way?

推荐答案

您似乎浏览了其中一个错误:

Looks like you glanced over one of the errors:

包@ngtools/webpack"与typescript"有不兼容的对等依赖(需要>=3.4 < 3.6"，会安装3.7.5").

尝试使用较低版本的 @ngtools/webpack，该版本适用于 TypeScript 3.4 到 3.5.

Try a lower version of @ngtools/webpack that works with TypeScript 3.4 to 3.5.

或者，将 package.json 中的 TypeScript 版本更新为 3.7.5 并运行 npm update，然后您应该能够更新 @angular/core &@angular/cli.

Alternatively, update your TypeScript version in the package.json to 3.7.5 and run npm update, then you should be able to update @angular/core & @angular/cli.
