我在angular2页面上遇到很多错误，在调试输出上，我可以看到很多JavaScript运行时错误和SourceMap读取失败 .

页面工作正常，只能在调试模式下看到它们，而不是在chrome中调试时在控制台中看到它们，但我认为由于这些错误，它会降低页面加载速度 . 任何帮助欣赏..

我怀疑这是由于我正在使用的软件包，这里是我的package.json，无法共享代码，因为它是一个大型项目“依赖项”：{“@ angular / animations”：“~4.0.3”，“@ angular / common“：”^ 4.0.0“，”@ angular / compiler“：”^ 4.0.0“，”@ angular / core“：”^ 4.0.0“，”@ angular / forms“：”^ 4.0 .0“，”@ angular / http“：”^ 4.0.0“，”@ angular / platform-browser“：”^ 4.0.0“，”@ angular / platform-browser-dynamic“：”^ 4.0.0 “，”@ angular / router“：”^ 4.0.0“，”@ angular / upgrade“：”^ 4.0.0“，”core-js“：”^ 2.4.1“，”es6-shim“：” ^ 0.35.3“，”ng2-toastr“：”^ 4.0.1“，”primeng“：”^ 2.0.2“，”reflect-metadata“：”^ 0.1.10“，”rxjs“：”^ 5.3 .0“，”systemjs“：”^ 0.19.39“，”zone.js“：”^ 0.8.4“}，”devDependencies“：{”gulp“：”^ 3.9.1“，”typescript“：” ^ 2.5.2“，”typings“：”^ 1.5.0“，”tslint“：”^ 5.1.0“，”merge-stream“：”^ 1.0.1“，”toastr“：”^ 2.1.2 “，”“下划线”：“^ 1.8.3”，“angular”：“^ 1.5.8”，“jquery”：“^ 3.2.1”，“@ types / core-js”：“^ 0.9.34” ，“@ types / jasmine”：“^ 2.5.35”，“@ types / angular”：“1.5.8”，“@ types / underscore”：“”，“@ types / node”：“~6.0.60 “，”@ type s / toastr“：”“}}
