Ubuntu 18.04：安装作曲家：无法写入文件“/usr/local/bin/composer”

我正在尝试使用安装作曲家教程在 Ubuntu 18.04 上。我收到以下错误消息：

$ sudo php composer-setup.php --install-dir=/usr/local/bin --filename=composer
[sudo] password : 
All settings correct for using Composer
Downloading...

Retrying...

感谢您的任何帮助。

我已经删除/usr/local/bin/composer并从头开始安装过程，现在它可以正常工作了。

当我输入以下命令时，出现以下错误消息：

$ 作曲家

In JsonFile.php line 98:
                                                                               
  Could not read /home/tonguim/.composer/config.json                           
                                                                               
  file_get_contents(/home/tonguim/.composer/config.json): failed to open stre  
  am: Permission denied

但是当使用

$ sudo composer

我得到的所有信息均正确，如下所示：

  / ____/___  ____ ___  ____  ____  ________  _____
 / /   / __ \/ __ `__ \/ __ \/ __ \/ ___/ _ \/ ___/
/ /___/ /_/ / / / / / / /_/ / /_/ (__  )  __/ /

                    /_/
Composer version 2.0.12 2021-04-01 10:14:59

为了在不被 sudom 的情况下运行 composer，我做了以下事情：

// Clear cache
composer clearcache
// OR
composer clear-cache

// Completely remove the cache directory
sudo rm -rf ~/.composer
