how to install multiple package in puppet 4?

I am testing existing custom code from 3.1 to 4.5.2 on puppet. It is for minicoda package installation.

class profile::hadoop::miniconda {
# Install miniconda default env (usually running python 2.7)
   exec { 'install_miniconda':
     command => '/test/python_module_install.sh',
     timeout => 1620,
     onlyif => '/usr/bin/test ! -d  /opt/miniconda'
  }

# Install miniconda python 3.4.3 env (py34) unless already installed
# It may fail at first run ever because "conda env" is not supported
# before an actual environment is created first
   exec { 'install_miniconda_py34':
     command => '/opt/miniconda/bin/conda create -n py34 python=3.4.3',
     unless => "/opt/miniconda/bin/conda env list| grep py34",
     require => Exec["install_miniconda"],
  }

        define miniconda_package{ $conda = "/opt/miniconda/bin/conda"

           exec { "miniconda_${name}":
               command => "${conda} install --yes  ${name}",
               require => Exec["install_miniconda"],
               unless => "${conda} list ${name}| grep ${name}"
           }
       }
  # Install Python modules into /opt/miniconda/ default env (usually running python 2.7)
  miniconda_package{[numpy,scipy,pandas,scikit-learn,rpy2,statsmodels,scikit-image,sympy,pymc]:
       require => File["condarc"],
   }


        define miniconda_package_py34{ $conda = "/opt/miniconda/bin/conda"

           exec { "miniconda_${name}_py34":
               command => "${conda} install --yes -n py34 ${name}",
               require => Exec["install_miniconda"],
               unless => "${conda} list -n py34 ${name}| grep ${name}"
           }
       }
  # Install Python modules into /opt/miniconda/ py34 env (usually running python 3.4.3)
  miniconda_package_py34{[numpy,scipy,pandas,scikit-learn,rpy2,statsmodels,scikit-image,sympy,pymc]:
       require => File["condarc"],
   }

        define pip_package{ $pip = "/opt/miniconda/bin/pip"

           exec { "pip_${name}":
               command => "${pip} install --upgrade ${name} -i http://server/products/miniconda/pypi.python.org/simple",
               require => Exec["install_miniconda"],
               unless => "${pip} list | grep -i ${name}"
           }
       }
  # Install pip modules into /opt/miniconda/ default env (usually running python 2.7)
  pip_package{[pyDOE,happybase,gplearn]:
       require => File["condarc"],
   }

        define pip_package_py34{ $pip = "/opt/miniconda/envs/py34/bin/pip"

           exec { "pip_${name}_py34":
               command => "${pip} install --upgrade ${name} -i http://server/products/miniconda/pypi.python.org/simple",
               require => Exec["install_miniconda"],
               unless => "${pip} list | grep -i ${name}"
           }
       }
  # Install pip modules into /opt/miniconda/ py34 env (usually running pythoni 3.4.3)
  pip_package_py34{[pyDOE,gplearn]:
       require => File["condarc"],
   }


   # To manage local repo's using .condarc file
   file { "condarc":
               ensure   => file,
               owner    => 'root',
               group    => 'root',
               mode     => '0644',
               source   => "puppet:///modules/profile/hadoop/miniconda_condarc",
               path     => "/root/.condarc",
               require  => Exec["install_miniconda"],
  }
}

Client side error Error: Could not retrieve catalog from remote server: Error 400 on SERVER: Evaluation Error: Error while evaluating a Resource Statement, Evaluation Error: Error while evaluating a Resource Statement, Invalid resource type miniconda_package

kindly let me know iif we need any modification on existing pp file for working in puppet 4.5.2.
