実行ファイルの移動

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

これで、直接 composer で利用できる。

アップデート

念の為、アップデート。


composer self-update
おまけ
インストール時警告

実は上記インストール時に、下記2行目の警告が出ていた。


curl -sS https://getcomposer.org/installer | php
PHP Warning:  Module 'intl' already loaded in Unknown on line 0
All settings correct for using Composer
Downloading...

Composer (version 1.6.2) successfully installed to: /root/composer.phar
Use it: php composer.phar

これは、php.ini で extension=intl.so をコメントアウトすることで消えたけど
CakePHP3 をインストールする際に intl は必要なはずなので、後ほど試す。

起動時警告

実は上記起動時に、下記2行目の警告が出ていた。


php composer.phar
Do not run Composer as root/super user! See https://getcomposer.org/root for details

あら、Composer って、root で利用してはいけないのね~。

実行ファイルを移動させて、一般ユーザに戻って利用したら
上記警告は出なくなった。

ちなみに、インストールを root でしたせいか
実行ファイルを移動しておかないと、php composer.phar では、実行できず


php composer.phar
Could not open input file: composer.phar

このように怒られた。。。
