权限被拒绝的错误与phantomjs [英] Permission denied error with phantomjs

问题描述

我在Ruby 2.0.0-p353和OSX Mavericks上使用Rails 4.0.2，Guard 2.2.4，guard-rspec 4.2.4，rspec-rails 2.14.0，Capybara 2.2.1和Poltergeist 1.5.0.

I am using Rails 4.0.2, Guard 2.2.4, guard-rspec 4.2.4, rspec-rails 2.14.0, Capybara 2.2.1 and Poltergeist 1.5.0 on Ruby 2.0.0-p353 and OSX Mavericks.

当我运行bundle execguard时，出现以下错误消息，但失败很多: 后钩中发生错误 Errno :: EACCES:权限被拒绝-/usr/local/Cellar/phantomjs 发生在/Users/gillesmath/.rvm/rubies/ruby-2.0.0-p353/lib/ruby/2.0.0/open3.rb:211:在'spawn'中

When I run bundle exec guard I got a lot of failure with this error message : An error occurred in an after hook Errno::EACCES: Permission denied - /usr/local/Cellar/phantomjs occurred at /Users/gillesmath/.rvm/rubies/ruby-2.0.0-p353/lib/ruby/2.0.0/open3.rb:211:in `spawn'

我检查了/usr/local/Cellar/phantomjs的权限，没有发现任何异常.我可以在不带"sudo"的情况下运行phantomjs.

I checked the permission on /usr/local/Cellar/phantomjs and didn't notice anything unusual. I can run phantomjs without 'sudo'.

我的spec_helper文件如下所示: ENV ["RAILS_ENV"] || ='测试' 需要File.expand_path("../../config/environment"，文件) 需要'rspec/rails' 需要'rspec/autorun' 需要"capybara/rspec" 需要'webmock/rspec' 需要水豚/poltergeist"

My spec_helper file look like this : ENV["RAILS_ENV"] ||= 'test' require File.expand_path("../../config/environment", FILE) require 'rspec/rails' require 'rspec/autorun' require "capybara/rspec" require 'webmock/rspec' require 'capybara/poltergeist'

Dir [Rails.root.join("spec/support/* / .rb")].each {| f |要求f}

Dir[Rails.root.join("spec/support/*/.rb")].each { |f| require f }

ActiveRecord :: Migration.check_pending！ (ActiveRecord :: Migration)

ActiveRecord::Migration.check_pending! if defined?(ActiveRecord::Migration)

WebMock.disable_net_connect！(:net_http_connect_on_start => true，:allow_localhost => true)

WebMock.disable_net_connect!(:net_http_connect_on_start => true, :allow_localhost => true)

Capybara.javascript_driver =:poltergeist

Capybara.javascript_driver = :poltergeist

我看不到出什么问题了，因为rails应用程序和/usr/local/Cellar/phantomjs目录及其内容的owner:group是相同的.

I can't see what is wrong because the owner:group is the same for both the rails app and the /usr/local/Cellar/phantomjs dir and its content.

感谢您的帮助

推荐答案

该错误使它看起来像试图执行/usr/local/Cellar/phantomjs 目录而不是其中的可执行文件.我认为Poltergeist会扫描您的PATH以查找称为phantomjs的第一件事. /usr/local/Cellar在您的PATH中吗?

That error makes it look like it's trying to execute the /usr/local/Cellar/phantomjs directory instead of the executable inside it. I think Poltergeist scans your PATH for the first thing called phantomjs. Is /usr/local/Cellar in your PATH?

如果是这样，我建议将其取出，因为可执行文件永远不应直接出现在其中.

If so, I'd recommend taking it out, since executables should never appear in there directly.

如果不能，另一种选择是在设置代码中为Poltergeist配置指向phantomjs的显式路径:

If you can't, another option is to configure Poltergeist with an explicit path to phantomjs in your setup code: https://github.com/jonleighton/poltergeist#customization

似乎有人已经打开了一个拉动请求，并提供了跳过目录的修补程序在Poltergeist使用的 Cliver 宝石中，因此希望该问题很快得到解决！

It looks like someone has already opened a pull request with a fix to skip directories in the Cliver gem that Poltergeist uses, so hopefully that will be fixed soon!
