Question

我正在使用wdioV5和browserstack运行测试，但是出现以下错误：

ERROR @wdio/local-runner: Failed launching test session: TypeError: Cannot read property 'capabilities' of null

我试图检查调试日志，但无法弄清其背后的原因，有人遇到过类似的问题吗？

调试输出：

        'browserstack.local': true },
     firstMatch: [ {} ] },
  desiredCapabilities:

[0-0] 2019-06-06T13:34:00.481Z ERROR webdriver: Request failed due to Error: Session not started or terminated

如果有帮助，我的配置是：

 path: '/',
  specs: [ './specs/**/*.js' ],
  exclude: [],
  maxInstances: 10,
  capabilities: 
   [ { os: 'Windows',
       os_version: '10',
       browser: 'Chrome',
       browser_version: '73.0' } ],
  logLevel: 'trace',
  bail: 0,
  baseUrl: 'http://localhost:8000',
  waitforTimeout: 10000,
  connectionRetryTimeout: 90000,
  connectionRetryCount: 3,
  services: [ 'browserstack' ],
  framework: 'mocha',
  reporters: [ 'spec' ],
  mochaOpts: { timeout: 60000 },
  before: [Function: before],
  user: 'xxx',
  key: 'xxx',
  browserstackLocal: true,
  onPrepare: [Function: onPrepare],
  onComplete: [Function: onComplete] }

想出了它...出于某种原因，在wdio.conf.js中使用此选项后，在我将其删除的那一刻抛出了错误消息，它起作用了，这很生气：

path: '/'

在浏览器堆栈上运行测试会抛出“无法读取null的属性'capabilities'”
