Angular 4,angularfire2,元数据版本不匹配

Question

我有以下错误

模块c的元数据版本不匹配:/..../node_modules/angularfire2/index.d.ts,找到版本4,预期3.

如果我去查看我的package.json,我在版本5.0.0-rc.4上有angularfire2,在4.6.2上有firebase. 详情见屏幕截图

我尝试将angularfire2和firebase的版本更改为以前的版本,但没有任何效果.

有什么建议 ？谢谢.

Answer 1

我试过上面的解决方案,但它没有解决我的问题.我尝试了以下步骤,它解决了我的问题.

npm install angularfire2 firebase --save运行命令时实际发生了该问题.以下依赖项已添加到package.json中

"angularfire2": "^5.0.0-rc.4",
"firebase": "^4.7.0"

这里的实际问题是由于angularfire2的版本.我们需要angularfire2":"^ 5.0.0-rc.3而不是angularfire2":"^ 5.0.0-rc.4.我不知道为什么这个版本有问题.

以下是解决的步骤:

第1步:卸载angularfire2和firebase

npm uninstall angularfire2 firebase --save

第2步:安装angularfire2 5.0.0-rc.3版本

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

第3步:安装firebase

npm install firebase --save

第4步:检查package.json中添加的依赖项

"angularfire2": "^5.0.0-rc.3",
"firebase": "^4.7.0"

第5步:执行ng服务

ng serve

这解决了问题和应用程序编译成功.

Answer 2

这就是我解决这个问题的方法.按照我列出的步骤操作:

第1步:卸载以前安装的angularfire2 pacakge

npm uninstall angularfire2

第2步:安装angularfire2 5.0.0-rc.3

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

第3步:检查你的package.json

确保package.json中的依赖项下有以下行

"angularfire2": "^5.0.0-rc.3",
"firebase": "^4.6.0",

这就是我解决问题的方法.

Answer 3

我解决了

不得不将firebase和angularfire2设置为:

"firebase":"4.6.0", "angularfire2": "5.0.0-rc.3"

但后来又出现了另一个错误:
"@angular/compiler-cli" package was not properly installed. Error: Error: Cannot find module '@angular/compiler-cli'

一个npm安装修复它.
