我正在通過Avdi Grimm的耙系列教程系列,我卡在Part 6。該調用Pandoc做工精細的任務,但口徑的ebook-convert
命令返回一個狀態127:Calibre電子書轉換命令未找到

cat ch1.html ch2.html ch3.html ch4.html > book.html
ebook-convert book.html book.epub

是在我的應用程序目錄的路徑:/Applications/calibre.app/Contents/MacOS/calibre
,而我的Rake文件是/Users/andrekibbe/code/rake_basics
:
require "rake/clean"
SOURCE_FILES = Rake::FileList.new("**/*.md", "**/*.markdown") do |fl|
fl.exclude("~*")
fl.exclude(/^scratch\//)
fl.exclude do |f|
`git ls-files #{f}`.empty?
end
end
CLEAN.include(SOURCE_FILES.ext(".html"))
task default: ["book.epub", "book.mobi"]
task html: SOURCE_FILES.ext(".html")
rule ".html" => ->(f){source_for_html(f)} do |t|
sh "pandoc -o #{t.name} #{t.source}"
end
file "book.html" => SOURCE_FILES.ext(".html") do |t|
chapters = FileList["**/ch*.html"]
backmatter = FileList["backmatter/*.html"]
sh "cat #{chapters} #{backmatter} > #{t.name}"
end
CLEAN.include("book.html")
file "book.epub" => "book.html" do |t|
sh "ebook-convert book.html #{t.name}"
end
CLOBBER.include("book.epub")
file "book.mobi" => "book.epub" do |t|
sh "kindlegen book.epub -o #{t.name}"
end
CLOBBER.include("book.mobi")
def source_for_html(html_file)
SOURCE_FILES.detect{|f| f.ext('') == html_file.ext('')}
end
有沒有辦法在Rakefile中需要Calibre工具,比如gem,還是使用絕對路徑或符號鏈接?我不認爲這是必要的,因爲在Avdi的代碼中沒有這樣的東西。或者我需要在其他地方安裝Calibre?
