【Vagrant】The 'extra' flag on synced folders is now 'mount_options'の対処法
vagrant up
をした時に以下のエラーが出た。
There are errors in the configuration of this machine. Please fix the following errors and try again: vm: * The 'extra' flag on synced folders is now 'mount_options'
config.vm.share_folderの:extraの部分を:mount_optionsに修正すればOK
config.vm.share_folder("./www", :mount_options => ["dmode=777","fmode=777"])
参考
Vagrant1.3.5ではconfig.vm.synced_folderのパーミッションをmount_optionsで設定する
