Question

在使用npm测试在visual studio代码中运行量角器测试时，得到以下错误，看起来像node_modules/@types/jasmine/index.d.ts的问题，如何摆脱这个错误？

我遇到了同样的问题，我修复了以下问题：

1）我将"@types/jasmine": "2.5.41"替换为"@types/jasmine": "^2.5.51"和 "typescript": "~2.0.0"

的"typescript": "2.1"

2）我执行了npm install && npm test。我收到了一个新错误，所以接下来我做了两个步骤。

3）我执行了node_modules / .bin / webdriver-manager update

4）在conf.ts评论该线路 seleniumAddress: 'http://localhost:4444/wd/hub',

5）我执行npm test并且它有效。

npm test在运行量角器打字稿时抛出错误
