pyinstaller将Python脚本打包成可执行程序,使在没有Python环境的机器上运行python
最新版是pyinstaller 3.1.1。支持python2.7和python3.3+。
可运行在Windows,Mac和Linux操做系统下。
但它不是跨编译的,也就是说在Windows下用PyInstaller生成的exe只能运行在Windows下,在Linux下生成的只能运行在Linux下。windows
使用命令pip install pyinstaller便可
在windows下,pyinstaller须要PyWin32的支持。当用pip安装pyinstaller时未找到PyWin32,会自动安装pypiwin32app
出现Successfully installed pyinstaller-3.1.1 pypiwin32-219即表示安装成功dom
打包的app里并不包含任何源码,但将脚本的.pyc文件打包了。python2.7
基本语法:
pyinstaller options myscript.py
经常使用的可选参数以下:
--onefile 将结果打包成一个可执行文件
--onedir 将全部结果打包到一个文件夹中,该文件夹包括一个可执行文件和可执行文件执行时须要的依赖文件(默认)
--paths=DIR 设置导入路径
--distpath=DIR 设置将打包的结果文件放置的路径
--specpath=DIR 设置将spec文件放置的路径
--windowed 使用windows子系统执行,不会打开命令行(只对windows有效)
--nowindowed 使用控制台子系统执行(默认)(只对windows有效)
--icon=<FILE.ICO> 将file.ico添加为可执行文件的资源(只对windows有效)ui
如pyinstaller --paths="D:\Queena" guess_exe.py加密
写好游戏文件guess_exe.py,代码以下:spa
__author__ = 'qa-2' # -*- coding:utf-8 -*- # 摇3次骰子,当总数total,3<=total<=10时为小,11<=total<=18为大 import random import time def enter_stake(current_money): '''输入小于结余的赌资及翻倍率,未考虑输入type错误的状况''' stake = int(input('How much you wanna bet?(such as 1000):')) rate = int(input("What multiplier do you want?你想翻几倍?(such as 2):")) small_compare = current_money < stake * rate while small_compare == True: stake = int(input('You has not so much money ${}!How much you wanna bet?(such as 1000):'.format(stake * rate))) rate = int(input("What multiplier do you want?你想翻几倍?(such as 2):")) small_compare = current_money < stake * rate return stake,rate def roll_dice(times = 3): '''摇骰子''' print('<<<<<<<<<< Roll The Dice! >>>>>>>>>>') points_list = [] while times > 0: number = random.randrange(1,7) points_list.append(number) times -= 1 return points_list def roll_result(total): '''判断是大是小''' is_big = 11 <= total <= 18 is_small = 3 <= total <= 10 if is_small: return 'Small' elif is_big: return 'Big' def settlement(boo,points_list,current_money,stake = 1000,rate = 1): '''结余''' increase = stake * rate if boo: current_money += increase print('The points are ' + str(points_list) + ' .You win!') print('You gained $' + str(increase) + '.You have $' + str(current_money) + ' now.' ) else: current_money -= increase print('The points are ' + str(points_list) + ' .You lose!') print('You lost $' + str(increase) + '.You have $' + str(current_money) + ' now.' ) return current_money def sleep_second(seconds=1): '''休眠''' time.sleep(seconds) # 开始游戏 def start_game(): '''开始猜大小的游戏''' current_money = 1000 print('You have ${} now.'.format(current_money)) sleep_second() while current_money > 0: print('<<<<<<<<<<<<<<<<<<<< Game Starts! >>>>>>>>>>>>>>>>>>>>') your_choice = input('Big or Small: ') choices = ['Big','Small'] if your_choice in choices: stake,rate = enter_stake(current_money) points_list = roll_dice() total = sum(points_list) actual_result = roll_result(total) boo = your_choice == actual_result current_money = settlement(boo,points_list,current_money,stake,rate) else: print('Invalid input!') else: sleep_second() print('Game Over!') sleep_second(2) if __name__ == '__main__': start_game()
以后命令行,切换到guess_exe.py的目录下,
输入:操作系统
pyinstaller --onefile --nowindowed --icon=" D:\Queena\PyCharmProjects\dist1\computer_three.ico" guess_exe.py
就会在当前文件下造成build文件夹、dist文件夹和.spec文件。
dist里就是guess_exe.exe可执行文件。命令行
若是有打包错误,具体看build里的warn*.txt文档,里面详细记载了错误的缘由。通常都是库丢失。 spec文件告诉PyInstaller如何去处理脚本。它对脚本名以及大多数pyinstaller的可选参数进行加密。PyInstaller就是经过执行spec文件的内容来build the app。
