Question

使用CLI在Angular 8.0.2中为应用程序生成了默认设置（减去路由）。

ng test有效，但ng e2e无效。该错误抱怨Chrome。

我承认我仍在学习Angular，但经过一番谷歌搜索后，我认为这个问题是resolved，所以为什么会发生这种情况以及如何解决呢？我的Chrome浏览器版本（显示为大约chrome）是Chrome版本74.0.3729.169

Answer 1

手动将Chrome更新到最新版本，然后重新启动Chrome。现在e2e测试工作了。

Answer 2

Chromedriver需要在本地安装特定版本的chrome，因此请确保您在本地安装的Chrome与驱动程序使用的版本相同。

出于某些原因，Chrome有时无法自动升级，但是如果您转到关于Google Chrome浏览器的帮助->，则可以看到当前版本，然后单击此处的按钮进行升级。
