It looks like you have a permission issue.
您似乎遇到了权限问题。
What is the output of ls -l /var/www?
You should see that you have write permission (w) for public or that you are in the group listed.
的输出是ls -l /var/www什么？您应该会看到您w对 public有写权限 ( ) 或者您在列出的组中。
For example, you might see
例如，您可能会看到
drwxr-xr-x 3 root root 4096 Jul 4 2015 .
Which means you would have issues writing to /var/wwwwithout acting as root.
这意味着您在/var/www不充当root.
Simply running sudo laravel new projectmight fix your current problem, but may incur you having to use sudowhenever you want to work.
简单地运行sudo laravel new project可能会解决您当前的问题，但可能会导致您在sudo想要工作时必须使用它。
A better solution would be to give yourself access to this directory:
更好的解决方案是让自己访问此目录：
sudo chmod o+w /var/www/
Running this command will give all (other) users (including you) on this machine write access to /var/www
运行此命令将尽数（Ø本机上疗法），用户（包括你）w ^仪式访问/var/www
