“无法创建缓存目录/home/<user>/.composer/cache/repo/https---packagist.org/，或者目录不可写。在没有缓存的情况下继续”

Question

新手在这里。

我试图按照以下安装指南在我的 Ubuntu 中安装 MISP：INSTALL.ubuntu1804.txt

当涉及到这条指令时：

# Once done, install CakeResque along with its dependencies if you intend to use the built in background jobs:
cd /var/www/MISP/app
sudo -u www-data php composer.phar require kamisama/cake-resque:4.1.2

我懂了：

Cannot create cache directory /home/akatiubuntutest/.composer/cache/repo/https---packagist.org/, or directory is not writable. Proceeding without cache
Cannot create cache directory /home/akatiubuntutest/.composer/cache/files/, or directory is not writable. Proceeding without cache
./composer.json has been updated
Cannot create cache directory /home/akatiubuntutest/.composer/cache/repo/https---packagist.org/, or directory is not writable. Proceeding without cache
Cannot create cache directory /home/akatiubuntutest/.composer/cache/files/, or directory is not writable. Proceeding without cache
Loading composer repositories with package information
Updating dependencies (including require-dev)
  - Installing monolog/monolog (1.23.0)
    Downloading: 65%^C        

我在这里尝试了解决方案无法创建缓存目录！在使用 composer 创建 Laravel 项目时帮我解决这个问题：

sudo chown -R <user> /home/<user>/.composer/cache/repo/https---packagist.org

但是（好吧，从逻辑上讲，因为它还没有被创建）我得到了这个：

chown: cannot access '/home/<user>/.composer/cache/repo/https---packagist.org/': No such file or directory

我已经安装了 PHP 和依赖项：

# Install PHP and dependencies
sudo apt-get install libapache2-mod-php php php-cli php-gnupg php-dev php-json php-mysql php-opcache php-readline php-redis php-xml php-mbstring

现在，我不确定我错过了什么。

Answer 1

如果有人通过这里，这是更短的解决方案：

sudo chown -R $USER $HOME/.composer

Answer 2

在我看来，您的命令中缺少组信息

sudo chown -R <user> /home/<user>/.composer/cache/repo/https---packagist.org

应该是

sudo chown -R <user>:<group> /home/<user>/.composer/cache/repo/https---packagist.org

但为了避免其他权限问题，我宁愿建议：

sudo chown -R <user>:<group> /home/<user>/.composer/cache

（您需要访问那里的其他文件夹）和

sudo chown <user>:<group> /home/<user>/.composer

确保您的用户对全局作曲家文件夹具有足够的权限。注意缺少的递归，因此用户不拥有由 root 创建的密钥。如果您需要查找组：

groups <user>
