在Ubuntu上安装Composer

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 Failed: Failed to open stream: Permission denied
Downloading...
Download Failed: Failed to open stream: Permission denied
Downloading...
Download Failed: Failed to open stream: Permission denied
The download Failed repeatedly,aborting.

我不知道为什么？你有好主意吗？我试着谷歌但没什么.

你的curl命令以root身份运行(通过sudo),但你的PHP命令不是.尝试在管道(“|”)和“PHP”之间移动sudo(假设您希望安装程序首先以root身份运行…).
