角编译器-没有成员期望的符号
提问于 2017-07-27 09:56:19
这个枚举为我抛出了一个例外：
export enum UserRole {
CareGiver = 0,
CareReceiver = 1
}错误是：
ERROR in Illegal state: symbol without members expected, but got {"filePath":"C:/Users/William-Work/Desktop/findchildcare/src/app/shared/enums/user_role_enum.ts","
le","members":["CareGiver"]}.
ERROR in ./src/main.ts
Module not found: Error: Can't resolve './$$_gendir/app/components/app/app.module.ngfactory' in 'C:\Users\William-Work\Desktop\findchildcare\src'
@ ./src/main.ts 3:0-89
@ multi ./src/main.ts有人能澄清我的枚举声明是否支持角吗？
有人能为这个问题提供一个解决方案吗？
我的package.json包含：
"@angular/animations": "^4.1.3",
"@angular/common": "^4.1.3",
"@angular/compiler": "^4.1.3",
"@angular/core": "^4.1.3",
"@angular/forms": "^4.1.3",
"@angular/http": "^4.1.3",
"@angular/platform-browser": "^4.1.3",
"@angular/platform-browser-dynamic": "^4.1.3",
"@angular/cli": "^1.1.2",
"@angular/compiler-cli": "^4.1.3",
"@angular/language-service": "^4.1.3",我也尝试过这个4.0.0和4.3.0，同样的问题。

正如janousek在这里中提到的，错误的发生是因为这段代码是角的：
// Stop simplification at builtin symbols or if we are in a reference context
if (expression === self.injectionToken || expression === self.opaqueToken ||
self.conversionMap.has(expression) || references > 0) {
return expression;
}修正将降级到4.2.X版本，例如4.2.6
