【问题描述】：
我正在处理一个相对较旧的 Ionic 项目，该项目由在我之前在我公司工作的其他人编写，但我无法正确构建它。原因是当我运行 npm install 时，我收到了太多关于对等依赖项的警告。
我尝试手动安装对等依赖项，但没有成功。我认为这可能是由于依赖版本之间的一些冲突。但我完全迷失了，因为我是 Ionic 和 npm 的新手。 我尝试通过将对等依赖项添加到 peerDependencies 部分来更新我的 package.json 文件。现在是这样的：
"dependencies": {
"@angular/common": "^6.0.0",
"@angular/compiler": "4.1.3",
"@angular/compiler-cli": "4.1.3",
"@angular/core": "^7.0.0",

},
"devDependencies": {
"@ionic/app-scripts": "^3.2.4",
"@ionic/cli-plugin-cordova": "1.4.1",
"@ionic/cli-plugin-ionic-angular": "1.3.2",
"install-peers": "^1.0.3",
"typescript": "2.3.4"
},
"peerDependencies": {
"@angular/common": "4.1.3",
"@angular/compiler": "6.1.10",
"@angular/core": "4.1.3",
"@angular/platform-browser": "4.1.3",

"@firebase/app-types": "0.x",
"@firebase/util": "0.x",
"rxjs": "5.4.0",
"zone.js": "~0.8.26"
}
如您所见，有些依赖项在依赖项和 peerDependencies 部分具有不同的版本。而且我不知道我能做些什么。
我安装了一个名为 install-peers 的 npm 包，当我执行 npm install 时，我得到了这个：
> install-peers@1.0.3 postinstall /Users/matheushr/workspace/Plis/plis-frontend/node_modules/install-peers
> node install.js
Installed peerDependencies as devDependencies via npm.

尝试构建项目，我收到以下错误：

我真的不知道如何让它工作。
