水貂>僵尸.js无法启动会话

Question

我正在尝试与僵尸驱动程序创建貂连接，但我得到一个错误。所有的端口都是打开的，我已经尝试使用我的服务器IP。

我代码:

$driver = new BehatMinkDriverZombieDriver('127.0.0.1');
$zombieSession = new BehatMinkSession($driver);
$zombieSession->start();

错误:

Fatal error: Uncaught exception 'RuntimeException' with message 'Server process has 
been terminated: (127) [sh: node: command not found ]' in /home/runniog5/public_html/subdomains/testing4/vendor/behat/mink-zombie-driver/src/Behat/Mink/Driver/NodeJS/Server.php:406

Answer 1

确保您已经安装了Node并且它可以正常工作。Server process has been terminated: (127) [sh: node: command not found ]告诉您shell找不到节点命令。为了验证你已经得到它，运行node -v，它应该打印当前安装的版本。

Answer 2

问题是ZombieServer不知道节点二进制文件的路径。要解决这个问题，使用以下代码:

$zombieServer = new ZombieServer($host, $port, $pathToYourNodeBinary, $serverPath, $threshold, $pathToYourNodeModules);
$zombieDriver = new ZombieDriver($zombieServer);
$session = new Session($zombieDriver);
$mink = new Mink(array('zombie' => $session));

在我的例子中，$ pathtoyournodebary和$ pathtoyournodemomodules是:

$pathToYourNodeBinary = '/usr/local/bin/node';
$pathToYourNodeModules = '/usr/local/lib/node_modules/';

你可以使用这些命令来了解你的路径(如果你运行的是Mac和OSX):

which node
which npm

当然，您需要设置其余的ZombieServer构造函数变量。要了解默认值，只需查看供应商库或github.com
