javascript - 类型错误 : Cannot read property 'match' of undefined 中的错误

Question

我正在尝试为 Angular 2 项目创建生产版本。我在 ng-build -prod 命令中遇到此错误..

从命令 **ng build -prod 记录。**

ERROR in TypeError: Cannot read property 'match' of undefined

通过 ng-serve 在本地部署应用程序效果很好。然而，ng build -prod 却没有。任何帮助将不胜感激。我认为我的 Angular 包之间存在版本不匹配。

版本。

@angular/cli: 1.0.0-rc.4
node: 7.0.0
os: win32 x64
@angular/cli: 1.0.0-rc.4
@angular/common: 2.4.7
@angular/compiler: 2.4.7
@angular/core: 2.4.7
@angular/forms: 2.4.7
@angular/http: 2.4.7
@angular/platform-browser: 2.4.7
@angular/platform-browser-dynamic: 2.4.7
@angular/router: 3.4.7
@angular/compiler-cli: 4.0.0-rc.5
@ngtools/webpack: 1.2.14

重现步骤。

ERROR in TypeError: Cannot read property 'match' of undefined

这不是您的代码中的错误。这是 suppress-entry-chunks-webpack-plugin.js:40 filterFn

中的错误
