pyinstaller將Python腳本打包成可執行程序,使在沒有Python環境的機器上運行python
最新版是pyinstaller 3.1.1。支持python2.7和python3.3+。
可運行在Windows,Mac和Linux操做系統下。
但它不是跨編譯的,也就是說在Windows下用PyInstaller生成的exe只能運行在Windows下,在Linux下生成的只能運行在Linux下。windows
使用命令pip install pyinstaller便可
在windows下,pyinstaller須要PyWin32的支持。當用pip安裝pyinstaller時未找到PyWin32,會自動安裝pypiwin32app
出現Successfully installed pyinstaller-3.1.1 pypiwin32-219即表示安裝成功dom
打包的app裏並不包含任何源碼,但將腳本的.pyc文件打包了。python2.7
基本語法:
pyinstaller options myscript.py
經常使用的可選參數以下:
--onefile 將結果打包成一個可執行文件
--onedir 將全部結果打包到一個文件夾中,該文件夾包括一個可執行文件和可執行文件執行時須要的依賴文件(默認)
--paths=DIR 設置導入路徑
--distpath=DIR 設置將打包的結果文件放置的路徑
--specpath=DIR 設置將spec文件放置的路徑
--windowed 使用windows子系統執行,不會打開命令行(只對windows有效)
--nowindowed 使用控制檯子系統執行(默認)(只對windows有效)
--icon=<FILE.ICO> 將file.ico添加爲可執行文件的資源(只對windows有效)ui
如pyinstaller --paths="D:\Queena" guess_exe.py加密
寫好遊戲文件guess_exe.py,代碼以下:spa
__author__ = 'qa-2' # -*- coding:utf-8 -*- # 搖3次骰子,當總數total,3<=total<=10時爲小,11<=total<=18爲大 import random import time def enter_stake(current_money): '''輸入小於結餘的賭資及翻倍率,未考慮輸入type錯誤的狀況''' stake = int(input('How much you wanna bet?(such as 1000):')) rate = int(input("What multiplier do you want?你想翻幾倍?(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?你想翻幾倍?(such as 2):")) small_compare = current_money < stake * rate return stake,rate def roll_dice(times = 3): '''搖骰子''' 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): '''判斷是大是小''' 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): '''結餘''' 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) # 開始遊戲 def start_game(): '''開始猜大小的遊戲''' 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()
以後命令行,切換到guess_exe.py的目錄下,
輸入:操作系統
pyinstaller --onefile --nowindowed --icon=" D:\Queena\PyCharmProjects\dist1\computer_three.ico" guess_exe.py
就會在當前文件下造成build文件夾、dist文件夾和.spec文件。
dist裏就是guess_exe.exe可執行文件。命令行
若是有打包錯誤,具體看build裏的warn*.txt文檔,裏面詳細記載了錯誤的緣由。通常都是庫丟失。 spec文件告訴PyInstaller如何去處理腳本。它對腳本名以及大多數pyinstaller的可選參數進行加密。PyInstaller就是經過執行spec文件的內容來build the app。
