ruby on rails - Uninitialized constant Capybara -


i'm having problem running test in rails capybara. whenever run it, tells me have 'uninitialized constant capybara (nameerror)' in spec_helper.rb file.

i'm following tutorial: http://www.railstutorial.org/book/static_pages#code-capybara_dsl

this spec_helper.rb

rspec.configure |config|   config.include(capybara::dsl) end

and i'm trying run test static_pages_spec.rb

require 'spec_helper'   describe "static pages"  "should have content 'sample app'"   visit '/static_pages/home'   expect(page).to have_content('sample app') end

if there other more information needed let me know

--------update----------------

i figured out problem. version of rspec have creates rails_helper.rb file in spec folder. had do:

require 'capybara/rspec'

in file , config.include capybara::dsl in configurations.

-----new problem------------ problem saying 'visit' undefined. 

 undefined method `visit' #<rspec::examplegroups::staticpages::aboutpage:0x000001033f5d50>

i tried require 'capybara', , require 'capybara/dsl' still give me errors , some.

i sort of found out problem, i'm getting initialized constant capybara because in newer versions of rspec have new folder "rails_helper" when first create spec folder creates both rails_helper , spec_helper. first mock speck test in spec folder has @ top

require 'rails_helper'

i following tutorial told me require 'spec_helper' not true newer versions of rspec.

so added 

config.include(capybara::dsl)

in rails helper folder , worked, except error css believe because tests run headless not work. spec tests run fine after errors displayed though. if have more questions let me know.

commonjs - How to write a typescript definition file for a node module that exports a function? -

consider, toml node module can use: // toml.d.ts declare module toml { export function parse(value:string):any; } declare module "toml" { export = toml; } then: /// <reference path="../../../../../defs/toml/toml.d.ts"/> import toml = require('toml'); toml.parse(...); however, node module export single function, such 'glob' ( https://github.com/isaacs/node-glob ). the node usage of module be: var glob = require("glob") glob("*.js", {}, callback(err, files) { ... }); you'd naively expect this: // glob.d.ts declare function globs(paths:string, options:any, callback:{(err:any, files:string[]):void; ...but because typescripts 'import' semantics bit strange, seems can use 'import .. = require()' statement alias modules . trying call: /// <reference path="../../../../../defs/glob/glob.d.ts"/> import blog = require('glob'); results in: error ts2072: mod...
