“path”参数必须是字符串类型。接收到的类型对象 - Angular 7

Question

我尝试在我的角度项目打字上运行测试

ng test --browsers=PhantomJS

之前，我必须使用命令手动安装 phantomjs

npm install phantomjs-prebuilt@2.1.16 -ignore-scripts

但是当ng test --br ...我收到这个错误后

我该如何修复它？提前致谢

Answer 1

我能够通过"karma-phantomjs-launcher"从karma.conf.js

注意：之所以能够做到这一点，是因为我们没有使用phantomjs，据我了解，它已经被弃用了一段时间了。
