当我耙,我得到了这个错误。
AllenLins-MacBook-Pro:geoblacklight allenlin$ rake -t Resolving dependencies... You must `gem install bundler` and `bundle install` to run rake tasks rake aborted! LoadError: cannot load such file -- rspec/core/rake_task /Users/allenlin/Documents/USpatial/geoblacklight/Rakefile:12:in `require' /Users/allenlin/Documents/USpatial/geoblacklight/Rakefile:12:in `' /Users/allenlin/.rbenv/versions/2.2.2/lib/ruby/2.2.0/rake/rake_module.rb:28:in `load' /Users/allenlin/.rbenv/versions/2.2.2/lib/ruby/2.2.0/rake/rake_module.rb:28:in `load_rakefile' /Users/allenlin/.rbenv/versions/2.2.2/lib/ruby/2.2.0/rake/application.rb:689:in `raw_load_rakefile' /Users/allenlin/.rbenv/versions/2.2.2/lib/ruby/2.2.0/rake/application.rb:94:in `block in load_rakefile' /Users/allenlin/.rbenv/versions/2.2.2/lib/ruby/2.2.0/rake/application.rb:176:in `standard_exception_handling' /Users/allenlin/.rbenv/versions/2.2.2/lib/ruby/2.2.0/rake/application.rb:93:in `load_rakefile' /Users/allenlin/.rbenv/versions/2.2.2/lib/ruby/2.2.0/rake/application.rb:77:in `block in run' /Users/allenlin/.rbenv/versions/2.2.2/lib/ruby/2.2.0/rake/application.rb:176:in `standard_exception_handling' /Users/allenlin/.rbenv/versions/2.2.2/lib/ruby/2.2.0/rake/application.rb:75:in `run' /Users/allenlin/.rbenv/versions/2.2.2/lib/ruby/gems/2.2.0/gems/rake-10.4.2/bin/rake:33:in `' /Users/allenlin/.rbenv/versions/2.2.2/bin/rake:23:in `load' /Users/allenlin/.rbenv/versions/2.2.2/bin/rake:23:in `'
但是,我运行’gem install bundler’和’bundle install’rspec / core / rake_task实际上存在,显示为
AllenLins-MacBook-Pro:geoblacklight allenlin$ gem which rspec/core/rake_task /Users/allenlin/.rbenv/versions/2.2.2/lib/ruby/gems/2.2.0/gems/rspec-core-3.0.4/lib/rspec/core/rake_task.rb
我迷失在这里。 非常感谢您对此的任何帮助! 我附上了Gemfile:
source 'https://rubygems.org' # Specify your gem's dependencies in geoblacklight.gemspec gemspec # If we don't specify 2.11.0 we'll end up with sprockets 2.12.0 in the main # Gemfile.lock but since sass-rails gets generated (rails new) into the test app # it'll want sprockets 2.11.0 and we'll have a conflict gem 'sprockets', '2.11.0' # If we don't specify 3.2.15 we'll end up with sass 3.3.2 in the main # Gemfile.lock but since sass-rails gets generated (rails new) into the test app # it'll want sass 3.2.0 and we'll have a conflict gem 'sass', '~> 3.2.0' gem 'bootstrap-sass', ">= 3.2" group :test do # Peg simplecov to 0.7.1', require: false gem 'coveralls', require: false end

添加我的gemenv,如果这是有帮助的

似乎运行bundle exec rake -t
会起作用。 Per bundler.io http://bundler.io/man/bundle-exec.1.html我建议添加bundle exec以确保我们使用当前上下文中指定的Gem。 另见这篇SOpost。 bundle exec rake是什么意思?
之后:sudo gem install bundler
我创建了一个Gemfile:
gem 'rake' gem 'rspec' gem 'kramdown'
并做了捆绑安装。 现在我没有得到错误。
假设你的Gemfile中确实有rspec,如果你收到这个错误,或者意味着你没有使用应用程序需要的正确gems运行rake(使用应用程序根目录中的bundle exec rake
来解决),或者你的尚未安装rspec核心gem。
如果在运行bundle install
,在运行bundle exec rake
时仍然会遇到相同的错误,请检查您是否确实安装了“测试模式”gems。 这发生在我身上。
在我的情况下,我没有安装我的测试gem,因为Bundler通过记住传递给--without
选项的先前参数表现出非常规行为,如此处所述 ,因此您可能认为在运行bundle install
时安装了所有gembundle install
但你可能实际上正在运行(例如…) – 没有--without development test
,也不知道它。
检查“未安装组开发和测试中的gem”之类的内容。 在bundle install
输出结束时。
要重置捆绑选项,只需删除./.bundle
目录(so … rm -r ./.bundle
)。 现在bundle install
将恢复正常,rake应该可以工作。
在生产环境中
会发生什么, capistrano
配置为仅在production
组中安装gem bundle(如在Gemfile中)。 因此它运行bundle命令,如bundle install --without development test
。
想validation?
在生产环境中的项目目录中运行bundle install
命令,您将看到以下内容
Using devise 4.2.0 Using activeadmin 1.0.0.pre4 Using responsive_active_admin 0.0.5 Bundle complete! 60 Gemfile dependencies, 133 gems now installed. Gems in the groups development and test were not installed. Bundled gems are installed into /path/to/your/app/production/shared/bundle.
请注意( 未安装组开发和测试中的Gems。 )。
您可能还记得,您已指定仅在development
模式下安装rspec-rails
gem。
解
尝试指定RAILS_ENV
类的
# For Rails 5.0 + RAILS_ENV=production bundle exec rails -T # or RAILS_ENV=production bundle exec rake -T # but this may not work bundle exec rake -T RAILS_ENV=production
