geckodriver.exe not in current directory or path variable, Selenium 2.53.1 + Firefox 48 + Selenium 3 Beta

问题

Seen a lot of questions regarding Selenium 2.53.1 and Firefox 47.0.1, but none in regards to the Selenium 3 Beta release. I am attempting to use the new gecko/marionette Firefox webdrivers, but even though I have the driver location in; my environment path, Firefox install folder in programs, and give the drive location in the system environment, it will still not work correctly.

Error:

The geckodriver.exe does not exist in the current directory or in a directory on the PATH environment variable. The driver can be downloaded at https://github.com/mozilla/geckodriver/releases.

Using:

• Selenium 2.53.1 server
• Firefox 48
• Selenium 3 Beta DLLs
• Window 10

Example Code 1

    using OpenQA.Selenium.Firefox;

    public static class FirefoxInitialise
    {
         public static IWebDriver Driver {get; set;}

         Driver = new FirefoxDriver();
    }

Also attempted the below:

    using OpenQA.Selenium.Firefox;

    public static class FirefoxInitialise
    {
         public static IWebDriver Driver {get; set;}

         FirefoxDriverServices service = FirefoxDriverService.CreateDefaultService();
         service.FirefoxBinaryPath = @"C:\Program Files\Mozilla Firefox\firefox.exe";
         FirefoxOptions options = new FirefoxOptions();
         TimeSpan time = TimeSpan.FromSeconds(10);
         Driver = new FirefoxDriver(service, options, time);
    }

Any help or insight as to why the code still won't detect this driver would be greatly appreciated it.

Try to put the geckodriver.exe in your path: C:\Users\YourName\Documents\Visual Studio 2013\Projects\seleniump\seleniump\bin\Debug

you can find geckodriver.exe at this link:

https://github.com/mozilla/geckodriver/releases

回答2:

Install the Selenium.Firefox.Webdriver NuGet package.

This will copy geckodriver.exe to the bin folder.

This solution may helps you fix problem: ( It did help me though)

public class TestResult {

    private IWebDriver driver;
    private StringBuilder verificationErrors;
    private string baseURL;
    private bool acceptNextAlert = true;

    [TestInitialize]
    public void SetupTest() {
        FirefoxDriverService service = FirefoxDriverService.CreateDefaultService(@"C:\geckodriver", "geckodriver.exe");
        service.Port = 64444;
        service.FirefoxBinaryPath = @"C:\Program Files (x86)\Firefox Developer Edition\firefox.exe";
        driver = new FirefoxDriver(service);
        baseURL = "http://localhost:49539";
        verificationErrors = new StringBuilder();
    }
}

If u include the geckodriver.exe in your project and you copy it to your target directory when you compile, the webdriver works as it did in previous versions.

回答5:

In your project, click on Tools --> Nuget Package Manager --> Manage NuGet Packages for Solution... The in the open Window Browse Selenium.FireFox.WebDriver Select Project and your project Name and click on install.

This is the easer form to put the driver on your Selenium Project.

This is for who is the begginers ill write the short version in the below after this post :) The easiest way first you need to download all drivers what browser you use and extract all drivers into e.g. C:\Selenium\ there and go to VisualStudio and from here add Selenium packages shown in the pictures Click here in console write this code PM>Install-Package Selenium.WebDriver after that copy your drivers directory and from windows search tab type variables and select (Edit the system environment and variables) shown pic2 in this windows you will have advanced tab at the below click Environment Variables... here you have System variables section find PATH or Path Variable and edit it be careful don't delete it!! next click new - paste directory of drivers and click all windws ok button that's all. restart your VS programm and ckeck it. After this you don't have to add director path into your Constructor like

IWebDriver driver2 = new InternetExplorerDriver(@"C:\Selenium"); 

One more thing don't forget to import files.

using OpenQA.Selenium;
using OpenQA.Selenium.Firefox;
using OpenQA.Selenium.IE;

For more Advanced IT guys.

1. Add into Environment Path Yours drivers directory.
2. VisualStudio install Selenium using NuGet package manager in console mode or how would u like.

   PM> Install-Package Selenium.WebDriver

3. restart VS.

I would try this:

1. First, make sure your C# project runs the same .NET framework version as the Client Driver's libraries (when you download them from Selenium HQ, you should see the framework version they're based on). I have 3.5 and 4.0 as of 9/15/2017, so I had to downgrade my C# project to .NET 4.0 to use the 4.0 Client Driver libraries.

2. In your code, when creating the Firefox Driver Service, make sure you explicitly specify the path to where your geckodriver.exe is located. See how I've added a path parameter to your call to FirefoxDriverService.CreateDefaultService:

   using OpenQA.Selenium.Firefox;
   
   public static class FirefoxInitialise
   {
     private static IWebDriver Driver{get; set;}
     public static IWebDriver Init()
     {
      // I'm assuming your geckodriver.exe is located there:
      // @"C:\MyGeckoDriverExePath\geckodriver.exe"
      FirefoxDriverService service = FirefoxDriverService.CreateDefaultService(@"C:\MyGeckoDriverExePath\");
      service.FirefoxBinaryPath = @"C:\Program Files\Mozilla Firefox\firefox.exe"; // May not be necessary
      FirefoxOptions options = new FirefoxOptions();
      TimeSpan time = TimeSpan.FromSeconds(10);
      Driver = new FirefoxDriver(service, options, time);
      return Driver;
    }
   }
   

So you can use :

IWebDriver driver = FirefoxInitialise.Init();

回答8:

If you have the executable in path environment variable, it likely means that it doesn't have permission to access it. As a workaround, try to run Visual Studio as administrator.

Or you could move it to somewhere that it have permission. Eg:

var service = FirefoxDriverService.CreateDefaultService(@"D:\tmp\Binaries");
service.FirefoxBinaryPath = FirefoxBinary;

var options = new FirefoxOptions();
options.SetPreference("browser.private.browsing.autostart", true);

_driver = new FirefoxDriver(service, options, TimeSpan.FromSeconds(30));

There I put the binaries in D:\tmp\Binaries\ and specified it in the code to check the geckodriver there.

回答9:

I kept getting this error also & the only thing I could do to finally fix it (not sure if it's the best answer for everyone who has this issue) was I placed the geckodriver.exe in my main Library directory, then I opened webdriver.py:

/Library/Frameworks/Python.framework/Versions/3.6/lib/python3.6/site-packages/selenium/webdriver/firefox/webdriver.py

found the line where it says: executable_path="geckodriver", firefox_options=None,

and changed it to:

executable_path="/Library/geckodriver", firefox_options=None

回答10:

I was having a Visual Studio 2017 issue where the build would fail because it was looking in a non existent directory for the geckodriver exec. I also had added it using nuget pack manager. What I found was in Visual Studio->Project->Properties->Build it works if you make the build independent of the architecture: Platform target is Any CPU & either leave the other check boxes (Prefer 32-bit, Allow unsafe code, Optimize code) all unchecked or just have Prefer 32-bit checked (which is the default on my system). btw:my Application was a .NET Framework 4.5.2 Console Application

回答11:

This solution worked for me for VS2017. Just copied the geckodriver.exe to my project folder like this:

C:\Users\pedne\Desktop\C#\FirstSolution\FirstSolution\bin\Debug
