Any ideas what's the problem?

Edit: thanks for repliers, I add my Fastfile:

# This is the minimum version number required.
# Update this, if you use features of a newer version
fastlane_version "fastlane 2.39.2"

default_platform :ios

platform :ios do

  # 1
  desc "Creating a code signing certificate and provisioning profile"
  # 2
  lane :provision do
    # 3
    produce(
      app_name: 'mZone Poker',
      language: 'English',
      app_version: '1.0',
      sku: '123abc'
    )
    # 4
    cert
    # 5
    sigh(force: true) #other: sigh(adhoc: true) \ sigh(development: true)
  end

  desc "Create ipa"
    lane :build do
      increment_build_number
      gym
    end

  error do |lane, exception|
  # This block is called if there was an error running a lane.
  end

end

Answer 1

As KrauseFx answered, I wrote fastlane_version "fastlane 2.39.2" instead of fastlane_version "2.39.2"
