composer update时报错:has a broken sugnature

项目使用composer进行包管理,但是进行包升级时报以下错误,该怎么解决?

ubuntu@ubuntu-VGN-SR13-B:~/nginx/coolwifi$ composer selfupdate
PHP Fatal error:  Uncaught exception 'PharException' with message 'phar "/usr/local/bin/composer" has a broken signature' in /usr/local/bin/composer:13
Stack trace:
#0 /usr/local/bin/composer(13): Phar::mapPhar('composer.phar')
#1 {main}
  thrown in /usr/local/bin/composer on line 13

解决:删掉/usr/local/bin/composer后,重新下载composer.phar复制进去添加执行权限后正常

看似权限不够,请试试:
> sudo composer self-update
or

> sudo su
> composer self-update

似乎需要重新安装,请查看 issue on github.
