如何在码头用灯塔执行赛柏exec命令？

Question

当我试图在docker映像中执行cypress测试用例时，cypress将打开chrome的新窗口并执行以下命令

  cy.exec(`lighthouse https://www.google.com/ --preset desktop --output-path cypress/lighthouse-html-reports/google.html`)

还会打开新的铬窗口。它用非零错误码抛出色色机的误差.得到了这个错误。

请补充：

--chrome-flags="--no-sandbox --headless --disable-gpu"服从您的命令：

cy.exec(lighthouse https://www.google.com/ --preset desktop --output-path cypress/lighthouse-html-reports/google.html --chrome-flags="--no-sandbox --headless --disable-gpu")
