與中間人和Gemfile的依賴關係的錯誤

Question

我對ruby很新，但我想編譯一個與middleman完成的項目。

我已經證實，我有以下命令安裝的所有依存關係：

>> bundle install 
Using i18n (0.6.1) 
Using multi_json (1.7.3) 
Using activesupport (3.2.13) 
Using chunky_png (1.2.8) 
Using coffee-script-source (1.3.3) 
Using execjs (1.4.0) 
Using coffee-script (2.2.0) 
Using fssm (0.2.10) 
Using sass (3.2.8) 
Using compass (0.12.2) 
Using ffi (1.8.1) 
Using tilt (1.3.7) 
Using haml (4.0.2) 
Using hike (1.2.2) 
Using rack (1.4.5) 
Using url_mount (0.2.1) 
Using http_router (0.10.2) 
Using json (1.7.7) 
Using listen (0.7.3) 
Using syntax (1.0.0) 
Using maruku (0.6.1) 
Using bundler (1.3.5) 
Using rack-test (0.6.2) 
Using rb-fsevent (0.9.3) 
Using thor (0.15.4) 
Using middleman-core (3.0.13) 
Using rack-protection (1.5.0) 
Using sinatra (1.3.6) 
Using padrino-core (0.10.7) 
Using padrino-helpers (0.10.7) 
Using uglifier (1.2.7) 
Using middleman-more (3.0.13) 
Using sprockets (2.9.3) 
Using sprockets-sass (0.9.1) 
Using middleman-sprockets (3.0.11) 
Using middleman (3.0.13) 
Using rb-inotify (0.9.0) 
Your bundle is complete! 
Use `bundle show [gemname]` to see where a bundled gem is installed. 

如果我的Gemfile依賴編譯，它告訴我下面的：

>> bundle exec middleman build 
/var/lib/gems/1.9.1/gems/execjs-1.4.0/lib/execjs/runtimes.rb:51:in `autodetect': Could not find a JavaScript runtime. See https://github.com/sstephenson/execjs for a list of available runtimes. (ExecJS::RuntimeUnavailable)

    from /usr/local/bin/middleman:23:in `load' 
    from /usr/local/bin/middleman:23:in `<main>' 

我已經安裝一個JavaScript運行時間：

>> sudo gem install therubyracer 

如果我嘗試編譯wi thout的Gemfile中，這給了不同的版本錯誤：

>> middleman build 
    /var/lib/gems/1.9.1/gems/bundler-1.3.5/lib/bundler/runtime.rb:33:in `block in setup': You have already activated listen 1.2.2, but your Gemfile requires listen 0.7.3. Using bundle exec may solve this. (Gem::LoadError)

     from /var/lib/gems/1.9.1/gems/middleman-core-3.1.4/lib/middleman-core/load_paths.rb:30:in `setup_load_paths' 
     from /var/lib/gems/1.9.1/gems/middleman-core-3.1.4/bin/middleman:10:in `<top (required)>' 
     from /usr/local/bin/middleman:23:in `load' 
     from /usr/local/bin/middleman:23:in `<main>' 

我不知道我是否會這塊寶石增加的Gemfile，但將不得不推遲。我不知道我是否誤解了某些紅寶石，或者我做錯了。我很感激，如果有人能指導我解決我的錯誤。

感謝

這似乎是一個已知的「問題」是中間人不能/不會提供這些每個平臺的依賴性，見https://github.com/middleman/middleman/issues/276#issuecomment-4037229。

根據https://stackoverflow.com/a/7860385你可以添加以下到您的Gemfile：

gem "rb-inotify" 
gem "therubyracer" 

運行bundle install一次，然後bundle exec middleman build應該幫助你。
