having trouble installing composer
提问by Om3ga
I am installing composer with the following cammand
我正在使用以下命令安装作曲家
curl -s https://getcomposer.org/installer | php
But I am keep getting below error message
但我不断收到以下错误消息
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.
How can I install composer be removing above error?

After some research I found that php.inifile which is being used is in /etc/php.ini. However, when I checked this file in /etcfolder it wasn't there. /etcfolder contained php.ini.defaultfolder which linked to /private/etc/php.ini.default. So I added detect_unicode = Offin /etc/php.ini.defaultand the renamed this file to php.ini. Now when I execute below command
经过一番研究，我发现php.ini正在使用的文件在/etc/php.ini. 但是，当我在/etc文件夹中检查此文件时，它不存在。/etc文件夹包含php.ini.default链接到/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。现在当我执行以下命令时
curl -s https://getcomposer.org/installer | php
OR
或者
sudo curl -s https://getcomposer.org/installer | php
Then I get following errors
然后我收到以下错误
Zafars-MacBook-Pro:/ zafarsaleem$ sudo curl -s https://getcomposer.org/installer | php
#!/usr/bin/env php

I had the same error. I ended up adding sudo to the php side and it worked for me.
