安装作曲家时遇到问题

Question

我正在使用以下cammand安装composer

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

但我一直收到以下错误消息

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.

如何安装composer才能删除上述错误？

编辑

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)

经过一番研究后,我发现php.ini正在使用的文件是/etc/php.ini.但是,当我在/etc文件夹中检查此文件时,它不在那里./etc文件夹包含php.ini.default链接到的文件夹/private/etc/php.ini.default.所以我说detect_unicode = Off在/etc/php.ini.default和重命名该文件php.ini.现在我执行下面的命令

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

要么

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

然后我得到以下错误

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