我是个大口大口的新手。我使用VS 2015 Update 3来做我的项目。对于这个项目,我有几个使用TypeScript编写的服务和控制器类。我使用gulp来对那些由。ts文件编译的angular js文件进行排序、连接和丑化。这里,服务和控制器文件的顺序很重要,所以我在连接这些文件之前使用了"gulp-angular-filesort"配方。我尝试了两个版本。
版本1(参见下面的代码)。任务被命名为"min:appcompExp"),我在gulpfile.js文件中明确地按顺序列出js文件,结果最小化(min)文件正在工作,当我运行我的项目时没有问题。
用于版本2(参见下面的代码)。任务被命名为"min:appcompExp2"),我使用通配符列出SOURCE js文件名,以便在gulpfile.js中缩短代码。然而,结果最小化(最小)文件被创建,但它不工作,当我运行我的项目。这个错误看起来像依赖注入问题:控制器找不到相应的服务DI,尽管我看到这个版本的结果最小文件包含了所有的服务和控制器类。我使用ngularFilesort = require("gulp-angular-filesort"),但它对版本2没有帮助。
版本2使用gulp时的一个特定DI错误:
Error: $injector:unpr
Unknown Provider
Unknown provider: ContactSrvcProvider <- ContactSrvc <- ContactCtrl
有人可以解释为什么使用通配符为源js文件名不工作与gulp?
下面是我的gulpfile.js,其中列出了concat和uglify服务和控制器类的两个版本:

当你在gulp.src()
即["app/services/*.js", "app/controllers/*.js]
中使用通配符时,gulp正在按顺序读取app/services/
和app/controllers/
目录内的所有js文件。
当你显式列出gulp.src()
即["app/services/SessionSrvc.js", "app/services/UtilSrvc.js", app/services/BaseSrvc.js", etc.]
中的源文件时,gulp将按照特定的顺序读取这些js文件。
你的"min:appcompExp2"
gulp任务不工作的原因是因为gulp.src()
中通配符的使用扰乱了gulp处理的js文件的顺序。而你的"min:appcompExp"
gulp任务是工作的,因为你显式地列出了js文件的顺序,它应该被处理。
我敢打赌,如果你在"min:appcompExp"
gulp任务中修改了gulp.src()
的参数,以便js文件按顺序排序,它会像你的"min:appcompExp2"
gulp任务一样失败:
[
"app/services/AvatarSrvc.js",
"app/services/BaseSrvc.js",
"app/services/ContactSrvc.js",
"app/services/LoginSrvc.js",
"app/services/SessionSrvc.js",
"app/services/UtilSrvc.js",
"app/services/presidentsSrvc.js",
"app/services/RegisterSrvc.js",
"app/controllers/AvatarCtrl.js"
"app/controllers/BaseCtrl.js",
"app/controllers/ContactCtrl.js",
"app/controllers/LoginCtrl.js",
"app/controllers/LogoutCtrl.js",
"app/controllers/PresidentCtrl.js",
"app/controllers/PresidentDetailCtrl.js",
"app/controllers/RegisterCtrl.js",
]
我假设它是presidentsSrvc.js
的不区分大小写的排序顺序。
