安装composer时遇到问题

Question

我正在安装具有以下cammand 的composer

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

但我不断收到错误消息

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以删除上述错误？

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)

最新编辑

经过一些研究，我发现正在使用的php.ini文件在/etc/php.ini中。然而，当我在/etc文件夹中检查这个文件时，它不在那里。/etc文件夹包含链接到/private/etc/php.ini.default的php.ini.default文件夹。所以我在/etc/php.ini.default中添加了detect_unicode = Off，并将该文件重命名为php.ini。现在，当我执行以下命令时

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

或

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

如果您的系统中没有curl，您仍然可以使用以下命令安装composer

转到可以写入的目录，

cd yourDirectory
php -r "readfile('https://getcomposer.org/installer');" | php -d detect_unicode=off

sudo curl-sShttps://getcomposer.org/installer| sudo php----install dir=/usr/local/bin
