無法下載作曲家

我在下載 Composer 時遇到此類錯誤。

php composer-setup.php
All settings correct for using Composer
PHP Warning:  file_put_contents(/home/vasu/.composer/keys.dev.pub): failed to open stream: Permission denied in /home/vasu/composer-setup.php on line 468

簡單的方法

首先嘗試簡單的方法。由於評論中提到的錯誤訊息,這個答案包含了困難的方法。

sudo mkdir -p /usr/local/bin  
sudo apt-get install curl
curl -sS https://getcomposer.org/installer | php   
sudo mv composer.phar /usr/local/bin/composer   

在 Ubuntu 16.04 及更高版本中,可以從預設的 Ubuntu 儲存庫安裝 Composer。打開終端機並輸入:

sudo apt install composer  

艱辛的道路

首先檢查是否/usr/local/bin/存在,如果不存在則建立該/usr/local/bin/目錄。

sudo mkdir -p /usr/local/bin

如果/usr/local/bin/已經存在,上面的命令除了返回此訊息之外不會執行任何操作:

mkdir: cannot create directory ‘/usr/local/bin’: File exists

運行這些命令:

sudo chmod -R 755 /usr/local/bin/  
cd /usr/local/bin/
ls # list the old composer file(s)
sudo rm <old-composer-files> # delete the old composer file(s)
sudo apt-get install curl
curl -sS https://getcomposer.org/installer | php   
sudo mv composer.phar /usr/local/bin/composer  

然後,如果您composer在終端機中輸入,它將可以在您的系統中全域存取。
