我正在尝试使用以下命令安装composer：
sudo curl -s https://getcomposer.org/installer | PHP
而我收到此错误：
All settings correct for using Composer Downloading... Download @R_404_159@: @R_404_159@ to open stream: Permission denied Downloading... Download @R_404_159@: @R_404_159@ to open stream: Permission denied Downloading... Download @R_404_159@: @R_404_159@ to open stream: Permission denied The download @R_404_159@ repeatedly,aborting.
我不知道为什么？你有好主意吗？我试着谷歌但没什么.
