I came here looking for a solution for a similar error when I updated my typescript version, Mine was not a new project, I am running an angular2 project with "@angular/cli": "1.2.0". I updated my typescript version from 2.0.3to 2.7.2and then I was getting similar issues like below while running ng e2e.
当我更新我的打字稿版本时，我来到这里寻找类似错误的解决方案，我的不是一个新项目，我正在运行一个带有"@angular/cli": "1.2.0". 我将打字稿版本从 更新2.0.3为2.7.2，然后在运行ng e2e.

The proposed solutions in this post didn't work for me.
这篇文章中提出的解决方案对我不起作用。
I fixed it by updating ts-nodeto 5.0.1. Versions above this were giving errors like the one below while running ng e2eeven though I had experimentalDecoratorsset to truein tsconfig.json:
我通过更新ts-node到5.0.1. ng e2e即使我已experimentalDecorators设置为truein ，在此之上的版本在运行时也会出现如下错误tsconfig.json：
error TS1219: Experimental support for decorators is a feature that is subject to change in a future release. Set the 'experimentalDecorators' option to remove this warning
错误 TS1219：对装饰器的实验性支持是一项功能，在未来版本中可能会发生变化。设置 'experimentalDecorators' 选项以删除此警告
Apart from the above change, I also changed few lines in protractor.conf.js
除了上面的改动，我还改动了几行 protractor.conf.js
Changed:
更改：
beforeLaunch: function () {
require('ts-node').register({
project: 'e2e'
});
},
to
到
beforeLaunch: function () {
require('ts-node/register')
}
This is for people who may stumble into this post and the proposed solution doesn't work for them.
这适用于可能偶然发现这篇文章并且提议的解决方案对他们不起作用的人。

if only the "npm install -g typescript" doesn't work.
如果只有“npm install -g typescript”不起作用。
try to do "tsc" in the project folder
尝试在项目文件夹中执行“tsc”
