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...
