NameError：未初始化的常量Chef :: Resource :: PythonPip

Question

enter image description here我正在关注Mining社交媒体第2版的书籍，在Twitter上做一些数据科学。我下载了包含必要文件和文件夹等的文件...... 在试图流浪时（它使用Vagrant来控制一个ipython笔记本将被执行的VM（一个virtualBox虚拟机）），我想出了一个奇怪的错误：NoNameError ：未初始化的常数厨师::资源:: PythonPip 这里是default.tb文件： 默认[ '蟒'] [ 'INSTALL_METHOD'] = '包'

if node['python']['install_method'] == 'package' 
    case node['platform'] 
    when "smartos" 
    default['python']['prefix_dir']   = '/opt/local' 
    else 
    default['python']['prefix_dir']   = '/usr' 
    end 
else 
    default['python']['prefix_dir']   = '/usr/local' 
end 

default['python']['binary'] = "#{node['python'] 
['prefix_dir']}/bin/python" 

default['python']['url'] = 'http://www.python.org/ftp/python' 
default['python']['version'] = '2.7.7' 
default['python']['checksum'] = 
'3b477554864e616a041ee4d7cef9849751770bc7c39adaf78a94ea145c488059' 
default['python']['configure_options'] = %W{--prefix=#{node['python'] 
['prefix_dir']}} 

default['python']['setuptools_script_url'] = 
'https://bitbucket.org/pypa/setuptools/raw/0.8/ez_setup.py' 
default['python']['pip_script_url'] = 'https://bootstrap.pypa.io/get-

Answer 1

python食谱明显标记为已弃用，并且根本不支持厨师13（或者只是一般，但我不会为厨师13修复它）。改为使用poise-python。

Answer 2

更改为poise-python是最好的解决方案，但可以修补旧的python食谱。了解为什么这个错误发生可能帮助其他人在他们的定制食谱类似的问题，因为它们移动到厨师13

厨师13不再创建自定义资源模块常量在发布说明指出https://discourse.chef.io/t/chef-client-13-released/10735

只有两行代码中的折旧蟒蛇食谱需要改变，从而与厨师工作13

在供应商/ virtualenv.rb：

- @current_resource = Chef::Resource::PythonVirtualenv.new(new_resource.name) 
+ @current_resource = Chef::Resource.resource_for_node(:python_virtualenv, node).new(new_resource.name) 

在供应商/ pip.rb：

- @current_resource = Chef::Resource::PythonPip.new(new_resource.name) 
+ @current_resource = ::Chef::Resource.resource_for_node(:python_pip, node).new(new_resource.name)
