安装作曲家时遇到问题 [英] having trouble installing composer

问题描述

我正在用以下cammand安装作曲家

  curl -s https://getcomposer.org/installer | php 
  

但我会不断收到错误讯息 b
$ b

  Zafars-MacBook-Pro：etc zafarsaleem $ curl -s https://getcomposer.org/installer | php 
＃！/ usr / bin / env php 
在您的机器上的某些设置使Composer无法正常工作。 
确保您修复了下面列出的问题并再次运行此脚本：
 
 detect_unicode设置必须禁用。 
将以下内容添加到您的`php.ini'的末尾：
 detect_unicode = Off 
 
 php.ini文件不存在。您必须创建一个。 
  

如何安装composer删除上述错误？

EDIT

  Zafars-MacBook-Pro：etc zafarsaleem $ php --ini 
配置文件（php.ini）路径：/ etc 
加载配置文件：（无）
扫描其他.ini文件：（无）
解析其他.ini文件： （无）
  

最新编辑 b $ b

经过一些研究，我发现使用的 php.ini 文件在 /etc/php.ini 。但是，当我检查这个文件在 / etc 文件夹中，它不在那里。 / etc 文件夹包含 php.ini.default 文件夹，链接到 / private / php.ini.default 。所以我在 /etc/php.ini.default 中添加了 detect_unicode = Off ，并将此文件重命名为 php.ini 。现在当我执行下面的命令

  curl -s https://getcomposer.org/installer | php 
  

或

  sudo curl -s https://getcomposer.org/installer |然后我得到以下错误
 
 
 <$ p 
 $ p>  Zafars-MacBook-Pro：/ zafarsaleem $ sudo curl -s https://getcomposer.org/installer | php

I am installing composer with the following cammand

curl -s https://getcomposer.org/installer | php

But I am keep getting below error message

Zafars-MacBook-Pro:etc zafarsaleem$ curl -s https://getcomposer.org/installer | php
#!/usr/bin/env php
Some settings on your machine make Composer unable to work properly.
Make sure that you fix the issues listed below and run this script again:

The detect_unicode setting must be disabled.
Add the following to the end of your `php.ini`:
detect_unicode = Off

A php.ini file does not exist. You will have to create one.

How can I install composer be removing above error?

EDIT

Zafars-MacBook-Pro:etc zafarsaleem$ php --ini
Configuration File (php.ini) Path: /etc
Loaded Configuration File:         (none)
Scan for additional .ini files in: (none)
Additional .ini files parsed:      (none)

Latest Edit

After some research I found that php.ini file which is being used is in /etc/php.ini. However, when I checked this file in /etc folder it wasn't there. /etc folder contained php.ini.default folder which linked to /private/etc/php.ini.default. So I added detect_unicode = Off in /etc/php.ini.default and the renamed this file to php.ini. Now when I execute below command

curl -s https://getcomposer.org/installer | php

OR

sudo curl -s https://getcomposer.org/installer | php

Then I get following errors

Zafars-MacBook-Pro:/ zafarsaleem$ sudo curl -s https://getcomposer.org/installer | php
#!/usr/bin/env php
All settings correct for using Composer

How can I install composer on my computer and remove above problems? Please help

解决方案

To download / install on MacOSX, you can do the following steps or try the homebrew steps below:

1. Goto a directory you can write to:

   cd ~

2. get composer:

   curl -sS https://getcomposer.org/installer | php

3. move composer into a bin directory in your $PATH var:

   sudo mv composer.phar /usr/local/bin/composer

4. double check composer works

   composer about

5. (optional) Update composer:

   sudo composer self-update

Homebrew

brew update
brew tap homebrew/homebrew-php
brew tap homebrew/dupes
brew tap homebrew/versions
brew install php55-intl
brew install homebrew/php/composer
