我刚刚安装完Ubuntu 13.10.
我想尝试Phalcon,当我构建源代码(phalcon.so)时,我有这个错误:
from /home/fabrice/Downloads/cphalcon/build/32bits/phalcon.c:204:
/usr/include/php5/ext/pcre/php_pcre.h:29:18: fatal error: pcre.h: No such file or directory
#include "pcre.h"
^
compilation terminated.
make: *** [phalcon.lo] Erreur 1
我安装的灯是:
sudo apt-get install -y apache2 php5 mysql-server libapache2-mod-php5 php5-mysql php5-curl php5-imagick php5-mcrypt php5-memcache php5-sqlite php5-xdebug php-apc php5-intl php-mongo php5-dev GCC
有谁能够帮我 ？
我正在尝试使用网站上的教程学习Behat .
第一步就行,没有错误出现.
但是当我改变它时ls_project/features/bootstrap/FeatureContext.php,如教程第二步所示,我收到以下错误:'Behat\Behat\Context\BehatContext' not found.
应用更改的教程代码:
# features/bootstrap/FeatureContext.php
<?php
use Behat\Behat\Context\BehatContext,
Behat\Behat\Exception\PendingException;
use Behat\Gherkin\Node\PyStringNode,
Behat\Gherkin\Node\TableNode;
class FeatureContext extends BehatContext
{
/**
* @Given /^I am in a directory "([^"]*)"$/
*/
public function iAmInADirectory($dir)
{
if (!file_exists($dir)) {
mkdir($dir);
}
chdir($dir);
}
}
完整的错误日志:
11:51:33 / ME : /var/www/test-driven/behat/ls_project
$ behat
# features/bootstrap/FeatureContext.php
PHP Fatal error: Class 'Behat\Behat\Context\BehatContext' not found in /var/www/test-driven/behat/ls_project/features/bootstrap/FeatureContext.php on line 10
PHP Stack trace:
PHP 1. {main}() /opt/Behat/bin/behat:0
PHP 2. …任何人都知道如何在AppKernel.php中获取parameters.yml(或_dev)？
我想动态地改变getLogDir()变量('mylogsdir')？
AppKernel.php:
$this->rootDir.'/'.$this->environment.'/'.$myLogDir;
parameters.yml:
parameters:
myLogDir: 'logdir'
可能吗 ？
非常感谢Fabrice
在升级pip后,我尝试进行'pip冻结',但是我发现了这个错误:
