我已經建構了一個偵聽 webhook 的 node.js 應用程序。目前它用於建構一個 jekyll 網站。

我已經在我的伺服器上配置了它，jekyll build當我在我的 jekyll 網站的根目錄中執行它（發送鉤子）時，它可以完美執行。當我在 shell 中通過 ssh 執行 node.js 應用程序時，當觸發 git 掛鉤時，一切正常。

但是，當從 upstart 腳本（如下所示）執行 node.js 應用程序時，它似乎找不到 gem。它一直在詢問我確定我已經安裝的依賴項（全域以及我的使用者）。

在我放置的腳本中echowhich jekyll``，這表明它確實指向本地安裝的jekyllbin: /home/christophe/.gem/ruby/2.0.0/bin/jekyll。但就在我執行 jekyll 命令的正下方，它失敗了：

/usr/lib/ruby/2.0.0/rubygems/dependency.rb:296:in `to_specs': Could not find 'jekyll' (>= 0) among 31 total gem(s) (Gem::LoadError)
   from /usr/lib/ruby/2.0.0/rubygems/dependency.rb:307:in `to_spec'
   from /usr/lib/ruby/2.0.0/rubygems/core_ext/kernel_gem.rb:47:in `gem'
   from /home/christophe/.gem/ruby/2.0.0/bin/jekyll:22:in `<main>'

如何執行此 bash 腳本以正確執行 jekyll？

gem env在腳本中，從通過 upstart 執行的 node.js 應用程序執行給出：

請注意，GEM_PATHS第二個條目中缺少主目錄前綴。我已經嘗試通過放入env GEM_PATH="/home/christophe/.gem/ruby/2.0.0"新貴腳本來解決這個問題，但這並沒有改變任何東西。

同時，我通過以 root 身份手動安裝一個 deps 列表來解決它。但是，我認為這不是一個好方法，因為暴發戶明確地以我的使用者身份執行。其次，該軟體需要在我沒有 root 權限的伺服器上執行。所以我仍然想知道一個修復。

sudo gem install jekyll
sudo gem install jekyll-gist
sudo gem install jekyll-cite
sudo gem install jekyll-scholar
sudo gem install addressable -v 2.3.5
sudo gem install yajl-ruby -v 1.2.0
sudo gem install pygments.rb
sudo gem install posix-spawn

經過幾個小時的痛苦，我終於修復了它。

訣竅是將其設置PATH為：/home/cdetroye/.rbenv/shims:/home/cdetroye/.rbenv/bin:/usr/local/bin:/usr/bin:/bin。

# /etc/init/libservice.conf
# Task to automatically start the library service.

author "Christophe De Troyer"
description "Run the githook for the blog."

# Path of the configuration files

env PATH=/home/cdetroye/.rbenv/shims:/home/cdetroye/.rbenv/bin:/usr/local/bin:/usr/bin:/bin

# Configure to run as `christophe`
setuid cdetroye
setgid cdetroye

script
   cd $PROJ
   gulp run
end script    

start on startup
#Respawn the process if it crashes
#If it respawns more than 10 times in 5 seconds stop
respawn limit 10 5

您是否嘗試設置GEM_HOME環境？我至少能夠通過以下方式獲得一個列出自定義安裝目錄的新貴服務：

cd
gem install rake --install-dir grepable

然後使用以下/etc/init/footest.conf服務：

author "Nobody"
description "Echo some details"

env GEM_HOME="/home/jdoe/grepable"

setuid jdoe
setgid jdoe

script
   /usr/bin/gem environment
end script    

start on startup
respawn limit 10 5

並且重啟後，

# fgrep -1 grep /var/log/upstart/footest.log

對於生產服務，可能會在供應商空間或主目錄中不合適的地方使用--install-dir/ 。GEM_HOME
