Title: Message Title

Dirk Heinrichs updated an issue   Puppet / PUP-11681 Package provider "pip3" fails to target pip from virtual env on first run Change By: Dirk Heinrichs *Puppet Version:* 7.20.0 *Puppet Server Version:* latest *OS Name/Version:* Debian 11 Given the following Puppet class:  {code:java} # Install Python, and optionally configure different virtual # environments with a set of given modules# Parameters: #   - venvs: A list of virtual environments to be installed, #       together with a set of modules. It should have the following #       content: # python::venvs: #   - name: foo #     modules: #       - name: bar #         version: 1.2.3 #       - name: baz #         version: latest #   - name: no_modules #     modules: [] #   ... # # NOTE: Module version defaults to latest if not specifiedclass python (   venvs = [], ) {   $venv_base_path = '/opt/venvs'  package { 'python3':     ensure  => latest,   }  ['python3-pip', 'python3-venv'].each |$pkg| {     package { $pkg:       ensure  => latest,       require => Package['python3'],     }   }  file { 'venv_base':     path    => $venv_base_path,     ensure  => directory,   }  $venvs.each |$venv| {     $venv_path = "${venv_base_path}/${venv['name']}/bin"     $pip = "${venv_path}/pip"    exec { "setup_venv_${venv['name']}":       command => "python3 -m venv --upgrade ${venv_base_path}/${venv['name']}",       path    => $facts['path'],       unless  => "test -L ${venv_path}/python3",     }    $venv['modules'].each |$module| {       $mod_ver = if $module['version'] {         $module['version']       }       else {         latest       }      package { "mod_${venv['name']}_${module['name']}":         name     => $module['name'],         ensure   => $mod_ver,         provider => 'pip3',         command  => $pip,         require  => Exec["setup_venv_${venv['name']}"],       }     }   } } {code} and the following input data:  {code:java} python::venvs:   - name: foo     modules:       - name: cffi   - name: bar     modules:       - name: celery   - name: baz     modules:       - name: celery         version: 4.4.7 {code}  the pip3 package provider fails on first run. *Desired Behavior:* First run of the class should succeed w/o error. *Actual Behavior:* The class needs two runs to succeed because the first one errors out with  {code:java} Error: Could not prefetch package provider 'pip3': Provider pip3 package command '/opt/venvs/bar/bin/pip' does not exist on this host {code} The second run finally succeeds because this time '/opt/venvs/bar/bin/pip' exists.
