错误错误:模块C的元数据版本不匹配:/projects/youtube-angular/firestore-app/node_modules/angularfire2/index.d.ts，找到了版本4，预期为3，
我从未见过。我尝试卸载所有内容并重新安装到最新版本，但仍然收到该错误。运行该项目的其他人似乎都没有这个问题。所以我猜这是一些本地设置或安装我有错，但无法弄清楚这一点。

最佳答案
我遇到了同样的问题，但通过将package.json文件中"angularfire2": "^5.0.0-rc.3"中的angtfire_code从"angularfire2": "^5.0.0-rc.4"更改为angularfire2的发行候选者来解决了这一问题。然后删除节点模块并运行npm i or npm install。
或者，您可以取消安装angularfire2，以确保您也将其从package.json和package.json.lock文件中删除。重新安装它并指定候选发布者，例如npm install [email protected] --save。
