在我的所有Rails项目中,当我运行rails s时,我得到以下输出:
Bundler is using a binstub that was created for a different gem.
This is deprecated, in future versions you may need to `bundle binstub rails` to work around a system/bundle conflict.
我已经看过处理项目的解决方案,但我可能遇到系统问题吗?
答案 0 :(得分:0)
如果您的系统中同时具有3.x和4.x,或者在我的系统中有两个具有不同bin名称的版本,则会发生这种情况,我使用3.2.22,其名称为railties
和4。 x bin名称是rails,Rubygems将在第一次安装时为gem创建一个binstubs,所以如果你像我先安装4.x rails一样,其他3.x项目将会收到此消息。
rails 4.x的binstub文件的最后一行是这样的:
加载Gem.bin_path('railties','rails',版本)
而3.x就是这个 加载Gem.bin_path('rails','rails',版本)
警告消息来自Bundler gem的rubygems_integration.rb第344行def replace_bin_path(specs)
gem_class = (class << Gem; self; end)
redefine_method(gem_class, :bin_path) do |name, *args|
exec_name = args.first
return ENV["BUNDLE_BIN_PATH"] if exec_name == "bundle"
spec = nil
if exec_name
spec = specs.find {|s| s.executables.include?(exec_name) }
raise(Gem::Exception, "can't find executable #{exec_name}") unless spec
unless spec.name == name
warn "Bundler is using a binstub that was created for a different gem.\n" \
"This is deprecated, in future versions you may need to `bundle binstub #{name}` " \
"to work around a system/bundle conflict."
end
else
spec = specs.find {|s| s.name == name }
raise Gem::Exception, "no default executable for #{spec.full_name}" unless exec_name = spec.default_executable
end
gem_bin = File.join(spec.full_gem_path, spec.bindir, exec_name)
gem_from_path_bin = File.join(File.dirname(spec.loaded_from), spec.bindir, exec_name)
File.exist?(gem_bin) ? gem_bin : gem_from_path_bin
end
end
因此解决方案是卸载所有导轨
gem uninstall rails
如果仍然存在,则删除binstub文件
which rails
rm -rf path_of_rails
并安装实际使用的rails版本
gem install rails -v 3.2.22
