Chrome kann mit GCE nicht erfolgreich mit Selenium gestartet werden

Ich habe eine Debian-basierte Google Compute Engine, um meine Selenium-Skripts auszuführen, ich kann jedoch keine Skripts ausführen, die mit Chrome verbunden sind. Ich habe versucht, sowohl Chrome als auch Chromium - und alle Abhängigkeiten - zu installieren, ohne weiter darüber nachzudenken. Es versagt immer noch

Das webdriverio-Skript: script.js

var webdriverio = require('webdriverio'); var options = { desiredCapabilities: { browserName: 'chrome' } }; var client = webdriverio.remote(options); client .init() .then(()=> { console.log('init ok') }, (err)=> { console.log('init failed', err) }) .url('https://duckduckgo.com/') .getTitle().then(function(title) { console.log('Title is: ' + title); }) .end();

Volle Ausgabe von node script.js

Dies ist im Grunde eine Untermenge des Fehlers des Selenium-Prozesses

Der Weg zur Erleuchtung begann mit dem Versuch, das Problem einzugrenzen.

Zumindest müssen diese Teile funktionieren, damit die Skripts ausgeführt werden können:

  1. Selen und Freunde ( webdriverio, ChromeDriver usw.)
  2. Chrome und Abhängigkeiten müssen installiert sein
  3. Xvfb muss funktionieren
  4. Chrome muss auf Xvfb laufen
  5. Chrome muss irgendwie auf Xvfb laufen, wenn es durch Selenium ausgelöst wird

Um es selenium-standalone startdurchzuarbeiten : Der schien fehlerfrei zu funktionieren, also war 1 OK. 2, 3 und 4 schienen gut zu funktionieren xvfb-run google-chrome --disable-gpu. Nicht sicher über 5 ...

Ein Zeiger, der in die Richtung der Kombination von Chrome + Selen zeigte, funktionierte nicht in einer Zeile in der Ausgabe:

Chrome failed to start: exited abnormally

Wir wissen, dass Chrome funktioniert, wenn X installiert ist. Wir wissen, dass Chrome fehlschlägt, wenn X nicht vorhanden ist.

Um 5 zum Laufen zu bringen, musste ich Xvfb irgendwie in den Mix einspritzen, was mir zwei Möglichkeiten gab. Umschließen Sie entweder den Knotenprozess oder den Selenprozess. Der erste hat nicht funktioniert, der zweite aber!

In einem Terminal:

xvfb-run selenium-standalone start

Im zweiten Terminal:

node /tmp/script.js

Und endlich bekam ich die richtige Antwort

init ok Title is: DuckDuckGo

Einige zusätzliche Debugging-Hilfe beim Einrichten dieses Problems

Es lohnt sich, die Ausnahmestapelspuren von Selenium durchzusehen, wenn Sie versuchen, das zu debuggen, was falsch ist.

Sie können sicher sein, dass Sie Chrome vermissen oder nicht installiert sind, wenn Sie dies erhalten

Caused by: org.openqa.selenium.WebDriverException: unknown error: cannot find Chrome binary (Driver info: chromedriver=2.30.477691 (6ee44a7247c639c0703f291d320bdf05c1531b57),platform=Linux 3.16.0-4-amd64 x86_64) (WARNING: The server did not provide any stacktrace information)

Wenn Sie nicht über die richtige Version von Chrome für Chromedriver verfügen, wenn Sie beispielsweise nur Chromium installiert haben (mein Fall!), Wird dieser Fehler angezeigt:

Caused by: org.openqa.selenium.SessionNotCreatedException: session not created exception: Chrome version must be >= 58.0.3029.0 (Driver info: chromedriver=2.30.477691 (6ee44a7247c639c0703f291d320bdf05c1531b57),platform=Linux 3.16.0-4-amd64 x86_64) (WARNING: The server did not provide any stacktrace information)

Stellen Sie sicher, dass google-chrome-stablees sich in dem befindet $PATHund dass Sie es erfolgreich auf einem Headless-System ausführen können.
