我在Ubuntu 14.04上尝试Mink (PHP);我基本上做了以下事情:
$ 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 zombie@4.2.1: wanted: {"node":"^4.0.0"} (current: {"node":"0.10.45","npm":"2.15.1"})
...
zombie@4.2.1 /usr/lib/node_modules/zombie
├── ms@0.7.1
├── debug@2.2.0
...
$ ls /usr/lib/node_modules/zombie/node_modules/
babel-runtime bluebird debug eventsource iconv-lite jsdom lodash mime ms request tough-cookie ws
所以,基本上,即使我收到警告,模块也会构建,并且应该在/usr/lib/node_modules
目录中。
然后我这样做:
mkdir test_php_mink
cd test_php_mink/
composer require behat/mink
composer require behat/mink-zombie-driver
作为支票:
test_php_mink$ ls
composer.json composer.lock vendor
......似乎所有composer
个文件都存在。
最后,根据http://mink.behat.org/en/latest/drivers/zombie.html(以及Cannot find module 'zombie' · Issue #84 · assaf/zombie · GitHub),我正在尝试此脚本:
<?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,这个脚本仍然失败了:
$ 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) [
module.js:340
throw err;

如何才能运行此基本示例?
编辑:用这个来玩了一下,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
...
...然后模块似乎被找到了!所以我的问题基本上减少为: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");
对我来说不起作用...
至于新错误,有Installing Zombie.js Error: ReferenceError: Set is not defined. What am I doing wrong? - 显然这是由于版本不匹配导致我收到警告(npm WARN engine zombie@4.2.1: wanted: {"node":"^4.0.0"} (current: {"node":"0.10.45","npm":"2.15.1"})
),所以我想我必须安装{{ 1}}所以我可以安装正确的nodejs版本;我也注意到nvm
:
Zombie 4.x 经过测试可与io.js 1.6 or later一起使用 如果您需要使用Node 0.12或更早版本,请考虑使用Zombie 2.x. ...
要安装Zombie.js,您需要io.js:
```庆典
$ npm install zombie --save-dev
```
...我认为也可以与/usr/lib/node_modules/zombie/README.md
一起安装;所以我试试看......
答案 0 :(得分:0)
好的,找到了某种看似有效的方法 - 但我仍然希望有更多知识渊博的人回答。
无论如何,诀窍是 - zombie
可以接受nodejs
二进制文件的路径;所以如果你不能真正从PHP传递nodejs
的环境变量,那么创建一个shell脚本来设置这些环境变量,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,我想在我的用户计算机和远程服务器上测试我的脚本,我的uid完全不同。无论如何,使用自定义可执行文件对此有所帮助。因此,在&#34; global&#34;中创建一个脚本。位置,我选择/home
,因此我需要sudo
在那里创建文件:
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;然后最终让它可执行:
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
$session->start();
?>
...或者,我刚刚意识到setNodeModulesPath($nodeModulesPath)
中有vendor/behat/mink-zombie-driver/src/NodeJS/Server.php
,所以我们可以完全删除代理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,它会输出:
$ php test_php_mink.php
NODE_PATH is: ''
NODE_PATH is: '/home/USERNAME/.nvm/versions/node/v4.0.0/lib/node_modules'
safe_mode: ''
......并且由于没有错误,我现在假设现在一切都很好......
