清单文件中未包含Javascript文件 [英] Javascript files are not included from manifest
问题描述
我正在使用Ruby On Rails，并且在Windows计算机上具有ActiveAdmin.我不认为ActiveAdmin与它有任何关系，但我只是在说.
I am using Ruby On Rails and have ActiveAdmin on top of that on a windows machine. I don´t think ActiveAdmin has anything to do with it, but I am just saying.
通过HTML包含的Javascript文件为/assets/active_admin.js，清单文件本身如下所示:
The Javascript file that is included via HTML is /assets/active_admin.js and the manifest file itself looks like this:
//= require active_admin/base
//= require just_datetime_picker/nested_form_workaround
当我运行Rails应用程序并打开http://localhost:3000/assets/active_admin.js时，日志告诉我active_admin.js已编译，但是该文件看起来仍然像清单一样，只是在末尾添加了分号:
When I run my Rails application and open http://localhost:3000/assets/active_admin.js, the log tells me, that active_admin.js was compiled, but the file still looks just like the manifest just with an added semicolon at the end:
//= require active_admin/base
//= require just_datetime_picker/nested_form_workaround
;
为什么不包含Javascript代码?
当我尝试通过bundle exec rake assets:precompile RAILS_ENV=development手动运行预编译管道时，它实际上创建了所有CSS文件，但是JS文件仍然看起来像上面描述的那样.
When I try to run the precompile pipeline manually via bundle exec rake assets:precompile RAILS_ENV=development, it actually creates all the CSS files, but the JS files still look like the one described above.
由于我在Windows计算机上运行，因此未安装gem'therubyracer'，但未安装NodeJS. bundle install也可以正常工作，我也没有收到任何错误.
Since I am operating on a windows machine, I do not have the gem 'therubyracer' installed, but NodeJS. Also the bundle install works fine and I also do not get any errors.
推荐答案
您是否正在使用Ruby v2.0?尝试降级到1.9.
Are you using Ruby v2.0? Try downgrading to 1.9.
症状: JavaScript清单文件未编译，未显示任何错误；但是，在预处理"资产后，文件末尾会出现一个神秘的分号;.
解决方案: 降级到Ruby v1.9.3！
