我正在实施一项非常基本的佣金任务：
filename lib / tasks / dosbis.rake
namespace :app do
desc "My first rake file"
task :dosbis => :environment do
end
end
当我使用以下命令执行时，我收到以下错误：
MacBook-Air-de-JCR:tasks jcr$ sudo bundle exec rake dosbis --trace

你似乎有不可见的角色\r。警告信息
在行中间遇到\ r \ n
建议这样做。
尝试让编辑器显示不可见的字符以查看不需要的字符。

desc必须与task
namespace :app do
desc "My first rake file"
task :dosbis => :environment do
end
end
