Question

蛋白石看起来很棒！！！当我尝试在两个不同的Windows 7和Windows 10系统上要求“ opal-jquery”时，出现相同的“找不到所需文件”错误：

C:\opaltest>node --version
v10.15.3

C:\opaltest>ruby -v
ruby 2.5.5p157 (2019-03-15 revision 67260) [x64-mingw32]

C:\opaltest>gem list -a opal

*** LOCAL GEMS ***

opal (0.11.4)
opal-jquery (0.4.3)

文件test.js.rb由以下三行组成：

require 'opal'
require 'opal-jquery'
puts 'success'

C:\opaltest>opal -c test.js.rb > test.js

- C:/Ruby/Ruby250-1-x64/lib/ruby/gems/2.5.0/gems/parser-2.3.3.1/lib

With the following extensions:
- .js
- .js.js
- .rb
- .js.rb
- .opal
- .js.opal
- .opalerb
- .js.opalerb
- .erb
- .js.erb

And the following processors:
- Opal::BuilderProcessors::JsProcessor
- Opal::BuilderProcessors::RubyProcessor
- Opal::BuilderProcessors::OpalERBProcessor
- Opal::BuilderProcessors::ERBProcessor

存在文件opal-jquery.rb：

C:\Ruby\Ruby250-1-x64\lib\ruby\gems\2.5.0\gems\opal-jquery-0.4.3\lib\opal-jquery.rb

但错误消息指示未搜索到包含该文件的目录。

如果我删除要求的“ opal-jquery”行以创建2行文件test_without_jquery.js.rb，则它起作用：

require 'opal'
puts 'success'

C:\opaltest>opal -c test_without_jquery.js.rb > test_without_jquery.js

C:\opaltest>node test_without_jquery.js
success

同时运行ruby的require语句可以正常工作

C:\opaltest>ruby test.js.rb
success

在opal进行编译时，我使用了Process Monitor实用程序来监视所有文件访问。 ruby可执行文件读取opal-jquery-0.4.3.gemspec文件，但从未尝试打开任何其他opal-jquery文件。显然，gemspec中的某些原因导致了此错误，但唯一的运行时依赖项是opal <0.12.0，> = 0.10.0，应由0.11.4满足。

我在Ubuntu 16.04，蛋白石0.11.4，蛋白石jquery 0.4.3上看到完全相同的“未找到“ test.js.rb”所需的文件”错误， ruby 2.3.1p112（2016-04-26修订版54768）[x86_64-linux]

非常感谢您的协助。谢谢!!!

您需要先在红宝石土地中要求opal-jquery或手动将opal-jquery的文件夹附加到由opal检查的文件夹：

lib/opal/jquery.rb#L12

如果要通过CLI进行操作，可以使用RUBYOPT：

export RUBYOPT="-ropal-jquery"
opal -c test.js.rb > test.js

require'opal-jquery'给出错误：找不到所需的文件
