无法使用 Angular 13.3 安装 ngx-graph

Question

我有一个 Angular v13.3 项目，我试图在其中安装 ngx-graph 的 v8.0.0。当我运行命令

npm install @swimlane/ngx-graph --save

我得到以下输出。

npm ERR! code ERESOLVE
npm ERR! ERESOLVE unable to resolve dependency tree

我很久没用过npm了，所以我不太清楚这是什么意思。 Angular 和 ngx-graph 要求的 rxjs 版本似乎有冲突。

Answer 1

npm install @swimlane/ngx-graph --save --legacy-peer-deps

几个版本之前，npm 自动为 peer deps 启动。使用上面的命令解决这个问题。
