node.js - 使用 Protractor 运行 chrome 驱动程序时获取 'E/launcher - spawn Unknown system error -86'

Question

Mac OSX 版本:Catalina 10.15.7
Node 版本:10.18.1
NPM 版本:6.13.4
Protractor 版本:5.4.2
Chrome 驱动程序版本:87.0.4280.88
Chrome 浏览器版本:87.0.4280.141(官方版本)(x86_64)
在直接针对本地 Chrome 浏览器运行一些 Protractor 测试时，我突然遇到了问题。我在运行 ng e2e --devServerTarget= 时遇到以下错误:

[12:33:36] I/launcher - Running 1 instances of WebDriver
[12:33:36] I/direct - Using ChromeDriver directly...
[12:33:36] E/launcher - spawn Unknown system error -86

我没有对我的 Protractor/ Chrome 驱动程序配置进行任何更改。它只是突然开始失败。我尝试过干净的构建，恢复我的更改，但我仍然遇到这个问题。请问有人可以帮忙吗？

今天早上我遇到了同样的错误，发现修复是运行:webdriver-manager update npm install --force protractor在最新的 webddriver-manager 更新中修复了这个问题。您需要强制对 Protractor 进行依赖更新才能使用最新的 webdriver-manager
