我想安装这两个包:

• "anahkiasen/former":"dev-master"
• "vespakoen/menu":"dev-master"

但作曲家说,他们每个人都依赖于这个包的不同版本:

• "anahkiasen/html-object":"dev-master"
• "anahkiasen/html-object":"1.1.2"

问题1

- Installation request for anahkiasen/former dev-master -> satisfiable by anahkiasen/former[dev-master].
- Can only install one of: anahkiasen/html-object[dev-master, 1.1.2].
- vespakoen/menu dev-master requires anahkiasen/html-object 1.1.2 -> satisfiable by anahkiasen/html-object[1.1.2].
- anahkiasen/former dev-master requires anahkiasen/html-object dev-master -> satisfiable by anahkiasen/html-object[dev-master].
- Installation request for vespakoen/menu dev-master -> satisfiable by vespakoen/menu[dev-master].

我该如何解决？

我需要帮助来弄清楚如何设置reply-to字段app/config/mail.php.我正在使用Laravel 4而且它不起作用.这是我的app/config/mail.php:

<?php

return array(
    'driver' => 'smtp',
    'host' => 'smtp.gmail.com',
    'port' => 587,
    'from' => [
        'address' => 'sender@domain.com',
        'name' => 'E-mail 1'
    ],
    'reply-to' => [
        'address' => 'replyto@domain.com',
        'name' => 'E-mail 2'
    ],
    'encryption' => 'tls',
    'username' => 'sender@domain.com',
    'password' => 'pwd',
    'pretend' => false,
);

我正在研究一个旧的PHP应用程序,用户的密码与该md5()功能进行哈希处理.所以密码存储如下:

我正在使用Laravel 4开发一个新的应用程序,我需要有关如何在users不丢失密码字段的情况下迁移表的建议.

我在Mac上安装并配置了AWS Elastic Beanstalk命令行工具.

这就是我安装的:

$ python --version
Python 2.7
$ ruby --version
ruby 2.0.0p195 (2013-05-14 revision 40734) [x86_64-darwin10.8.0]
$ eb --version
AWS Elastic Beanstalk Command Line Interface v2.6.3

我已正确配置EB以便在AWS中使用git

当我尝试将提交推送到AWS时,我收到此错误:

$ git aws.push
Traceback (most recent call last):
  File ".git/AWSDevTools/aws.elasticbeanstalk.push", line 21, in <module>
    from aws.dev_tools import * 
  File "/Applications/MAMP/htdocs/innbativel/.git/AWSDevTools/aws/dev_tools.py", line 3, in <module>
    from subprocess import check_output
ImportError: cannot import name check_output

有谁知道为什么以及如何解决它？

我正在使用Pharo在Smalltalk中编码.我的代码:

|i delay|
i := 0.
[i < 5] whileTrue: [
    [
        delay := Delay forSeconds: 2.
        delay wait.
        Transcript show: '2 seconds are up'.
        Transcript cr.
    ] fork.
    i := i + 1.
]

它会立即打印所有"2秒钟",而不是每2秒打印一次:

2 seconds are up
2 seconds are up
2 seconds are up
2 seconds are up
2 seconds are up

请问,有人能告诉我如何在Smalltalk中每2秒打印一些东西吗？

我有一个在Apache/PHP上运行的站点,并且作为性能问题,我编写了一个javascript来执行特定任务.

我在服务器上安装了node.js,以便运行这个javascript.当我从命令行调用脚本时,它工作正常.请参阅以下命令:

> node myscript.js

但是我需要它从php页面运行,我试图通过调用exec()PHP函数来做到这一点,如下所示:

<?php exec('node myscript.js >/dev/null/ 2>&1 &'); ?>

......但它不起作用.

难道我做错了什么？还有另一种方法可以做我想要的吗？

如何优化此SQL查询？

(SELECT SUM (same_field) FROM same_table WHERE other_same_field = '0') AS a,
(SELECT SUM (same_field) FROM same_table WHERE other_same_field = '1') AS b,
(SELECT SUM (same_field) FROM same_table WHERE other_same_field = '2') AS c
