如何在 macOS 上安装 Composer？

Question

我尝试在我的 macOS 版本上安装 Composer：

high sierra--> 10.13.4

但是使用命令后：

sudo php -r "copy('https://getcomposer.org/installer', 'composer-setup.php');" 

它创建了一些文件和目录，但没有下载作曲家。 我的终端显示以下错误：

未启用日志处理 - 使用 stderr 日志记录

创建目录：/var/db/net-snmp

创建目录：/var/db/net-snmp/mib_indexes`

如何解决这个问题？

Answer 4

Install download the composer using the following curl  command in the 
terminal:

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

After the command, you will have composer.phar file in the current 
directory and the composer command is available as:

php composer.phar [composer commnad]

In order to make composer available globally, you have to move the 
recently downloaded composer.phar to local user’s bin folder as follow:

go to /usr/local/bin folder . You can click  Shift + Command + G to open 
the dialog to go to folder.

move the recently downloaded composer.phar in the usr/local/bin folder
create a alias using command  alias composer="php 
 /usr/local/bin/composer.phar"


Now, you can access the composer from the terminal simply using the 
composer  command. Thats it.
