Bye bye...
despite that:
$ gem list | grep racer therubyracer (0.9.8) $ gem list | grep inotify rb-inotify (0.8.8)
I followed the RVM Installation Guide and the Middleman Getting Started. Any ideas why Middleman would fail to start a server?
回答1:
It seems that middleman server users a sandbox based solely on the Gemfile. If you've installed the gems globally, they'll not be present at runtime in the sandbox. The original Gemfile created by middleman init looks like:
source "http://rubygems.org"
gem "middleman", "~>2.0.13.1"
edit this to be:
source "http://rubygems.org"
gem "middleman", "~>2.0.13.1"
gem "rb-inotify"
gem "therubyracer"
You could be less lazy and parameterize this by Operating System, if you like.
回答2:
If you remove the Gemfile.lock file and then run in your root directory
bundle install --binstubs ./bin --path vendor/bundle
the bundle will install all the packages locally (and all the executables to start things up in ./bin )
You can also if it helps, try my template to get things started

This is the line you need to pay attention to
/home/blt/.rvm/gems/ruby-1.9.2-p290/gems/execjs-1.2.9/lib/execjs/runtimes.rb:47:in `autodetect': Could not find a JavaScript runtime. See https://github.com/sstephenson/execjs for a list of available runtimes. (ExecJS::RuntimeUnavailable)
Basically you need to install a js runtime like node js or v8 or something on your system so that execjs can work with it. Read this carefully
