Question

错误中的错误：模块C的元数据版本不匹配：/projects/youtube-angular/firestore-app/node_modules/angularfire2/index.d.ts，找到版本4，预期3，

我从未见过这个。我试图卸载所有内容并重新安装到最新版本，但仍然出现错误。没有其他人运行该项目似乎有这个问题。所以我猜这是一些本地设置或安装我错了但不能解决这个问题。

Answer 1

我遇到了同样的问题但是通过将angularfire2上的候选版本从package.json文件中的"angularfire2": "^5.0.0-rc.3"更改为3 "angularfire2": "^5.0.0-rc.4"来解决它。然后删除节点模块并运行npm i or npm install。

或者你可以unintall angularfire2确保你也从package.json和package.json.lock文件中删除它。重新安装它并指定候选版本npm install angularfire2@5.0.0-rc.3 --save。

Answer 2

在我的情况下，我不得不更改cli版本和angularfire2版本

npm install @angular/cli@ version 1.2.1 --save

npm install angularfire2@5.0.0-rc.3 --save

Answer 3

我尝试了一切，但它没有奏效。唯一能帮到我的答案是将@ angular / common，@ angular / compiler，@ angular / compiler-cli，＆＃34; @ angular / core等所有@angular软件包更新到最新版本（5.1.1）。

之后我还需要将rxjs更新为最新版本（5.5.5）。

使用--prod。
