Python 3 cx_Freeze 5.0.2导入错误：没有名为'idna'的模块

Question

我试图使用this site中的setup.py脚本将我的.py脚本转换为可执行文件。由于错误说明，尝试未成功：

ImportError: No module named 'idna'

这是setup.py脚本：

from cx_Freeze import setup, Executable
import sys

base = None

if sys.platform == 'win32':
    base = None


executables = [Executable("my first prog.py", base=base)]

packages = ["idna"]
options = {
    'build_exe': {

        'packages':packages,
    },

}

setup(
    name = "<any name>",
    options = options,
    version = "<any number>",
    description = '<any description>',
    executables = executables
)

以下是错误行：

关于什么是错的任何想法？我在我的电脑上运行python 3.6.2。
