在Homestead中使用：
还可以使用命令来达到效果：
sudo ln -s /home/vagrant/code/myapp/storage/app/public /home/vagrant/code/myapp/public/storage
PS:（参考）
I’m trying to link storage directories on Homestead, but when I try I get an error:
failed to create symbolic link public/storage Protocol error
the command was
ln -s /home/vagrant/code/myapp/storage/app/public /home/vagrant/code/myapp/public/storage
