我正在Ubuntu 14.04上尝试Mink (PHP);我基本上做了以下工作:

$ apt-show-versions nodejs
nodejs:amd64/trusty 0.10.45-1nodesource1~trusty1 uptodate
$ npm -v
2.15.1
$ sudo npm install -g zombie
npm WARN engine [email protected]: wanted: {"node":"^4.0.0"} (current: {"node":"0.10.45","npm":"2.15.1"})
...
[email protected] /usr/lib/node_modules/zombie
├── [email protected]
├── [email protected]
...

$ ls /usr/lib/node_modules/zombie/node_modules/
babel-runtime  bluebird  debug  eventsource  iconv-lite  jsdom  lodash  mime  ms  request  tough-cookie  ws


因此,基本上,即使我得到警告,模块也会构建,并且应该位于目录/usr/lib/node_modules中。

然后我做:

mkdir test_php_mink
cd test_php_mink/
composer require behat/mink
composer require behat/mink-zombie-driver


作为检查:

test_php_mink$ ls
composer.json  composer.lock  vendor


...似乎所有composer文件都在那里。

最后,根据http://mink.behat.org/en/latest/drivers/zombie.html(以及Cannot find module 'zombie' · Issue #84 · assaf/zombie · GitHub),我正在尝试以下脚本:

<?php

# composer autoload:
require_once __DIR__ . '/vendor/autoload.php';

echo "safe_mode: '" . ini_get("safe_mode") ."'\n"; # have PHP 5.5.9, safe_mode is removed

putenv("NODE_PATH=/usr/lib/node_modules");
echo "NODE_PATH is: '" . getenv ( "NODE_PATH" ) . "'\n"; # OK, is there

# NOPE:
#$driver = new \Behat\Mink\Driver\ZombieDriver();

$driver = new \Behat\Mink\Driver\ZombieDriver(
  new \Behat\Mink\Driver\NodeJS\Server\ZombieServer()
);

$session = new \Behat\Mink\Session($driver);

// start the session
$session->start();
?>


不幸的是,该脚本仍然失败,并且:

$ php test_php_mink.php
safe_mode: ''
NODE_PATH is: '/usr/lib/node_modules'
PHP Fatal error:  Uncaught exception 'RuntimeException' with message 'Server process has been terminated: (8) [

我如何才能运行此基本示例?



编辑:玩了更多,发现当我在命令行上指定环境变量时:

$ NODE_PATH=/usr/lib/node_modules php test_php_mink.php
safe_mode: ''
NODE_PATH is: '/usr/lib/node_modules'
PHP Fatal error:  Uncaught exception 'RuntimeException' with message 'Server process has been terminated: (8) [
/usr/lib/node_modules/zombie/node_modules/jsdom/lib/jsdom/level2/html.js:238
var nonInheritedTags = new Set([
                           ^
ReferenceError: Set is not defined
...


...然后似乎找到了该模块!所以我的问题基本上简化为:如何从我的php脚本中更改NODE_PATH环境变量,所以我不必在shell上指定它-因为显然putenv("NODE_PATH=/usr/lib/node_modules");不适用于我...

至于新的错误,有Installing Zombie.js Error: ReferenceError: Set is not defined. What am I doing wrong?-显然这是由于我收到(npm WARN engine [email protected]: wanted: {"node":"^4.0.0"} (current: {"node":"0.10.45","npm":"2.15.1"}))警告的版本不匹配所致,所以我想我必须安装nvm以便正确安装nodejs版本;而且我在/usr/lib/node_modules/zombie/README.md中也注意到了:


  Zombie 4.x经过测试可与io.js 1.6 or later一起使用。
  如果需要使用Node 0.12或更早版本,请考虑使用Zombie2.x。 ...
  要安装Zombie.js,您需要io.js
  ``
  $ npm安装僵尸--save-dev
  ```


...而且我认为也可以使用nvm安装;所以我尝试一下...

最佳答案

好的,找到了某种看似可行的方法-但我仍然希望有人能提供更多知识。

无论如何,诀窍是-zombie可以接受nodejs二进制文件的路径;因此,如果您不能真正从PHP传递nodejs的环境变量,请制作一个将设置这些环境变量的shell脚本,然后调用nodejs

首先这是我的安装:

# remove previous
sudo npm uninstall -g zombie --save-dev
sudo apt-get remove --purge nodejs && sudo apt-get autoremove --purge

# install new
curl -o- https://raw.githubusercontent.com/creationix/nvm/master/install.sh | bash
nvm install iojs-v3.3.1
npm list -g --depth=0
nvm install 4.0.0
npm list -g --depth=0
npm -g install zombie --save-dev


nvm的问题在于它安装在用户目录中,我想在用户机器和uid完全不同的远程服务器上测试脚本。无论如何,使用自定义可执行文件都会有所帮助。因此,在“全局”位置创建一个脚本,我选择了/home,所以我需要sudo在此处创建文件:

sudo touch /home/node_pth.sh


...然后粘贴以下内容:

#!/bin/bash
export NODE_PATH=/home/USERNAME/.nvm/versions/node/v4.0.0/lib/node_modules
#echo ARGS ARE "$@" | tee -a /tmp/node.log
/home/USERNAME/.nvm/versions/node/v4.0.0/bin/node "$@"


...当然,用正确的路径替换路径;然后最终使其可执行:

sudo chmod +x /home/node_pth.sh


现在,我们可以使用以下test_php_mink.php PHP文件:

<?php

$nodeModPath = "/home/USERNAME/.nvm/versions/node/v4.0.0/lib/node_modules"; # correct NODE_PATH, but will not help
$nodePath = "/home/node_pth.sh"; # shell script that sets NODE_PATH, then calls node executable

echo "NODE_PATH is: '" . getenv ( "NODE_PATH" ) . "'\n"; #
putenv("NODE_PATH=".$nodeModPath);
echo "NODE_PATH is: '" . getenv ( "NODE_PATH" ) . "'\n"; # is there - but still doesn't help with call

# composer autoload:
require_once __DIR__ . '/vendor/autoload.php';

echo "safe_mode: '" . ini_get("safe_mode") ."'\n"; # have PHP 5.5.9, safe_mode is removed


$driver = new \Behat\Mink\Driver\ZombieDriver(
  //~ new \Behat\Mink\Driver\NodeJS\Server\ZombieServer()
  # copy defaults here for everything but nodeBin;
  # see vendor/behat/mink-zombie-driver/src/NodeJS/Server.php
  new \Behat\Mink\Driver\NodeJS\Server\ZombieServer("127.0.0.1", 8124, $nodePath, null)
);

$session = new \Behat\Mink\Session($driver);

// start the session
$session->start();
?>




...或者,我只是意识到setNodeModulesPath($nodeModulesPath)中有vendor/behat/mink-zombie-driver/src/NodeJS/Server.php,所以我们可以完全删除proxy bash可执行文件:

<?php

$nodeModPath = "/home/USERNAME/.nvm/versions/node/v4.0.0/lib/node_modules"; # correct NODE_PATH, but will not help via putenv

echo "NODE_PATH is: '" . getenv ( "NODE_PATH" ) . "'\n"; #
putenv("NODE_PATH=".$nodeModPath);
echo "NODE_PATH is: '" . getenv ( "NODE_PATH" ) . "'\n"; # is there - but still doesn't help with call

# composer autoload:
require_once __DIR__ . '/vendor/autoload.php';

echo "safe_mode: '" . ini_get("safe_mode") ."'\n"; # have PHP 5.5.9, safe_mode is removed

$zsrv = new \Behat\Mink\Driver\NodeJS\Server\ZombieServer();
$zsrv->setNodeModulesPath($nodeModPath . "/"); # needs to end with a trailing '/'

$driver = new \Behat\Mink\Driver\ZombieDriver( $zsrv );

$session = new \Behat\Mink\Session($driver);

// start the session
$session->start();

?>


无论如何,当调用此脚本时,它输出:

$ php test_php_mink.php
NODE_PATH is: ''
NODE_PATH is: '/home/USERNAME/.nvm/versions/node/v4.0.0/lib/node_modules'
safe_mode: ''


...并且没有错误,我认为现在一切都很好...
