Question

我试图运行angular2-meteor应用程序，但是，当我在浏览器上打开它时，我收到一个错误：

constants.js：66Uncaught TypeError：无法读取属性＆＃39; CheckOnce＆＃39;的未定义

任何人都可以帮助我吗？

Answer 1

I met same error.

Like @barbatus said here, location of CheckOnce might have changed.

CheckOnce is from Angular2's ChangeDetectionStrategy. So I solve it by updating from

"@angular/common": "2.0.0-rc.1",
"@angular/core": "2.0.0-rc.1",
"@angular/platform-browser": "2.0.0-rc.1",
"@angular/platform-browser-dynamic": "2.0.0-rc.1",

to

"@angular/common": "2.0.0-rc.4",
"@angular/core": "2.0.0-rc.4",
"@angular/platform-browser": "2.0.0-rc.4",
"@angular/platform-browser-dynamic": "2.0.0-rc.4",

TypeError：无法读取属性＆＃39; CheckOnce＆＃39;未定义的
