无法在Angular 5-ng测试中运行单元测试

Question

While running ng tes t, I am getting error

" Uncaught TypeError: Zone.__load_patch is not a function ".

I checked the source code in the debugger console in chrome, it is showing error ../zone.js/dist/async-test.js_global. It was worked earlier but now seems some of the dependencies got upgraded.

Dev Dependencies version:

@Angular/cli: 1.2.7,
@angular/compiler-cli:~5.2.0,
@types/jasmine:2.5.38,
@types/jasminenewd:~2.0.2,
@types/node:~6.0.60,
karma:~1.4.1,
karma-chrome-launcher:~2.1.1,
Karma-cli: ~1.0.1, 
karma-jasmine: ~1.1.0, 
ts-node: ^3.3.0, 
talent: ~4.5.0

Dependencies: zone. js: ^0.8.4

Answer 1

You're using quite a new zone.js with an Angular CLI that's very outdated. That can't be right. Use the zone.js matching your angular version.
