Permission denied when running script/server

I just cloned the mini_fb_demo from Github, went into the directory and ran script/server, and got this error:

-bash: script/server: Permission denied

I've been using script/server like this for other projects for awhile, and this has nev开发者_运维技巧er happened. What is causing this? Thanks for reading.

You probably don't have execute permission on script/server.

Try: chmod +x script/server then start it again.
