Ошибка с зависимостями с посредником и Gemfile

Question

Я очень новичок в ruby, но хочу скомпилировать проект, который выполняется с помощью посредника.

Я подтвердил, что у меня есть все зависимости, установленные с помощью следующей команды:

>> 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. 

Если я компилирую с Gemfile зависимостей, он говорит мне следующее:

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

Я уже установил время выполнения JavaScript:

>> sudo gem install therubyracer 

И если я попытаюсь скомпилировать wi thout в Gemfile, это дает различные версии ошибки:

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

Я не знаю, если я хотел бы добавить этот драгоценный камень в Gemfile, но придется ставить. Я не знаю, неправильно ли я понял что-то рубин, или я ошибаюсь. Я ценю, если кто-то может направить меня к моей ошибке.

Благодаря

Вроде бы известная «проблема» что Посредник не может/не будет предоставлять эти PER-платформы зависимостей см https://github.com/middleman/middleman/issues/276#issuecomment-4037229.

По https://stackoverflow.com/a/7860385 вы можете просто добавить следующую строку в ваш Gemfile:

gem "rb-inotify" 
gem "therubyracer" 

Запуск bundle install один раз, а затем bundle exec middleman build должен помочь вам.
