node.js - E/启动器 - 进程已退出，错误代码为 135

Question

我正在尝试从我的 Windows 计算机运行 Protractor 测试。

使用的配置:

OS : Windows 7

Node : 6.11.3

Protractor : 5.1.2

NPM : 3.10.10

由于以下错误，我无法运行 Protractor 测试。

***E/launcher - Process exited with error code 135***

我不断收到上面堆栈跟踪中提到的错误“E/launcher - 进程已退出，错误代码为 135”。如何才能成功完成 Protractor 测试？
