php - Composer : file_put_contents(./composer.json):无法打开流:权限被拒绝

Question

我正在尝试安装 Prestissimo到 Ubuntu 16.04 服务器，但这会导致错误:

$ composer global require "hirak/prestissimo:^0.3"
Changed current directory to /home/kramer65/.composer


  [ErrorException]
  file_put_contents(./composer.json): failed to open stream: Permission denied


require [--dev] [--prefer-source] [--prefer-dist] [--no-progress] [--no-update] [--no-scripts] [--update-no-dev] [--update-with-dependencies] [--ignore-platform-reqs] [--prefer-stable] [--prefer-lowest] [--sort-packages] [-o|--optimize-autoloader] [-a|--classmap-authoritative] [--] [<packages>]...

我以用户 kramer65 的身份登录，所以我不知道为什么它不能写入我的主文件夹。我对 permission denied 的正常 react 是使用 sudo，但 composer 总是说:

Do not run Composer as root/super user! See https://getcomposer.org/root for details

知道如何解决这个问题吗？

Answer 1

我在安装 laravel/lumen 时遇到了这个问题。

可以通过以下命令解决:

$ sudo chown -R $USER ~/.composer/
