Error: The path to the driver executable must be set by the webdriver.chrome.driver system property
提问by Maxim Yefremov
I am trying node.js selenium web driver example...
我正在尝试node.js selenium web 驱动程序示例...
var webdriver = require('selenium-webdriver');
var driver = new webdriver.Builder().
usingServer('http://localhost:4444/wd/hub').
withCapabilities(webdriver.Capabilities.chrome()).
build();
driver.get('http://www.google.com');
driver.findElement(webdriver.By.name('q')).sendKeys('webdriver');
driver.findElement(webdriver.By.name('btnG')).click();
driver.wait(function() {
return driver.getTitle().then(function(title) {
return title === 'webdriver - Google Search';
});
}, 1000);
driver.quit();
... but got error
...但有错误
promise.js:1542
throw error;
^
UnknownError: The path to the driver executable must be set by the webdriver.chrome.driver system property; for more information, see http://code.google.com/p/selenium/wiki/ChromeDriver. The latest version can be downloaded from http://code.google.com/p/chromedriver/downloads/list
at new bot.Error (/Users/maks/Dropbox/nodeApps/orgi/node_modules/selenium-webdriver/lib/atoms/error.js:109:18)
I guessedto set PATH variable:
我猜想设置 PATH 变量：
$ cat .bashrc
export PATH=$PATH:/usr/local/git/bin/
export PATH=$PATH:~/bin
export PATH=$PATH:~/Dropbox/chromedriver
And restart console, but got the same error.
并重新启动控制台，但得到了同样的错误。

Using selenium-server-standalone-*.jar from here, you can pass webdriver.chrome.driverproperty when launching it like so:
从这里使用 selenium-server-standalone- *.jar ，您可以在启动它时传递属性，如下所示：webdriver.chrome.driver
java -jar selenium-server-standalone-2.35.0.jar -Dwebdriver.chrome.driver="D:\dev\chromedriver.exe"
This eliminates the error; Java command line option -Dproperty=valuesets a system property value as expected.
这消除了错误；Java 命令行选项-Dproperty=value按预期设置系统属性值。

Just in case some one getting this error :
以防万一有人收到此错误：
Exception in thread "main" com.beust.jcommander.ParameterException: Unknown option: -Dwebdrive
线程“main”com.beust.jcommander.ParameterException 中的异常：未知选项：-Dwebdrive
this threadmight help :
这个线程可能有帮助：
Use Parameters before jar file
在 jar 文件之前使用参数
java [-options] -jar jarfile [args...] (to execute a jar file)
So your command should be:
所以你的命令应该是：
java -jar -Dwebdriver.chrome.driver="D:\dev\chromedriver.exe" selenium-server-standalone-2.35.0.jar
Hope it helps someone in future.
希望它可以帮助将来的人。

If you don't want to use the selenium server but just want to use the chromedriver directly, something like this will work:
如果您不想使用 selenium 服务器而只想直接使用 chromedriver，则可以使用以下方法：
var chrome = require('selenium-webdriver/chrome');
var service = new chrome.ServiceBuilder(__dirname + '/node_modules/.bin/chromedriver').build();
var driver = new chrome.createDriver(capabilities, service);
It's not very well documented, I had to poke around the source code a bit.
它没有很好的文档记录，我不得不稍微浏览一下源代码。

The simplest solution I found is to make the chromedriver file executable.
我找到的最简单的解决方案是使 chromedriver 文件可执行。
Incorrect:
不正确：
**-rw-rw-r--** 1 user user 5560736 Jul 31 00:56 chromedriver
Correct:
正确的：
**-rwxrwxr-x** 1 user user 58204704 Aug 14 08:18 phantomjs
Once chromedriver matched phantomjs it sprang to life
一旦 chromedriver 与 phantomjs 匹配，它就会活跃起来

You can use the following code to set path in your code
您可以使用以下代码在代码中设置路径
System.setProperty("webdriver.chrome.driver", "your_path");
Path to be mentioned within quotes.
要在引号中提及的路径。
