Question

使用 Phantomjs 启动无头浏览器时，获取以下异常

java.lang.NoSuchMethodError: org.openqa.selenium.os.CommandLine.find(Ljava/lang/String;)Ljava/lang/String;
    at org.openqa.selenium.phantomjs.PhantomJSDriverService.findPhantomJS(PhantomJSDriverService.java:232)
    at org.openqa.selenium.phantomjs.PhantomJSDriverService.createDefaultService(PhantomJSDriverService.java:181)
    at org.openqa.selenium.phantomjs.PhantomJSDriver.<init>(PhantomJSDriver.java:104)
    at org.openqa.selenium.phantomjs.PhantomJSDriver.<init>(PhantomJSDriver.java:94)

操作系统是Mac

启动无头浏览器的配置是

File src = new File("src/test/resources/phantomjs_mac");
System.setProperty("phantomjs.binary.path", src.getAbsolutePath());
driver = new PhantomJSDriver();

更新了完整的跟踪

Answer 1

以下是您的问题的答案：

当我们使用Phantomjs时，我们必须提供Phantomjs可执行文件的绝对路径。在指定实施 WebDriver

之前，请务必指定new PhantomJSDriver();班级

以下是Windows中的示例：

 File path=new File("C:\\Utility\\phantomjs-2.1.1-windows\\bin\\phantomjs.exe");
 System.setProperty("phantomjs.binary.path",path.getAbsolutePath());
 WebDriver driver= new PhantomJSDriver();
 driver.manage().window().maximize();
 driver.navigate().to("https://www.google.co.in/");

PS：请将其转换为Mac可识别格式。

如果这回答你的问题，请告诉我。

Answer 2

System.setProperty（“phantomjs.binary.path”，src.getAbsolutePath（））在PhanotmJS的情况下不起作用但是，您可以设置DesiredCapabilities并将其传递给PhantomJSDriver。

DesiredCapabilities capabilities = new DesiredCapabilities();
capabilities.setCapability(PhantomJSDriverService.PHANTOMJS_EXECUTABLE_PATH_PROPERTY, System.getProperty("user.dir") + /drivers/phantomjs.exe");

WebDriver driver = new PhantomJSDriver(capabilities);
driver.navigate().to("https://www.google.co.in/");
driver.get("http://google.com");

确保您的pom文件不使用selenium 3.6.0版。相反，请使用以下依赖项。

<dependency>
        <groupId>org.seleniumhq.selenium</groupId>
        <artifactId>selenium-java</artifactId>
        <version>3.5.3</version>
</dependency>

另外，WebDriver driver = new PhantomJSDriver（）;将始终导致错误，因此您不能使用空构造函数。

我希望有所帮助。
