Gasp (Graphics API for Students of Python) will enable us to write PRograms involving graphics.
安裝Windows版GASP 在《How to Think Like a Computer Scientist Learning with Python 》4.11GASP章節(jié)中,需要安裝GASP。通過文章給的網(wǎng)址http://dev.laptop.org/pub/gasp/downloads進(jìn)入下載頁面。由于我是Windows 7系統(tǒng),所以選擇
3.Microsoft Windows
The latest version of GASP does not run on Windows, due to unfortunate implementation details. In the meantime, you can use older versions of GASP from the 0.2.x series. Install PyGame, then download and install the 0.2.0beta1 GASP package. Assistance with porting the 0.3.x series is appreciated, email the mailing list if you can help.
1.首先安裝PyGame,通過頁面鏈接,進(jìn)入http://www.pygame.org/wiki/GettingStarted
通過描述得知,在dos里面輸入pip install pygame 即可
但是我在這個(gè)過程中,第一次失敗了,仔細(xì)看錯(cuò)誤描述,要求先更新pip的版本。更新pip后,成功安裝pygame
2.下載python-gasp-0.2.0beta1.win32.exe,雙擊安裝。 由于我是windows 64系統(tǒng),gasp是32位的,一開始提示no python installation found in the registry。 解決辦法: win+r,輸入regedit,在注冊表新建HKEY_LOCAL_MACHINE/SOFTWARE/Wow6432Node/Python/PythonCore/2.7/InstallPath 項(xiàng),并把HKEY_LOCAL_MACHINE/SOFTWARE/Python/PythonCore/2.7/InstallPath的數(shù)據(jù)復(fù)制到上面新建的項(xiàng)里面
現(xiàn)在可以在Python27/Lib/site-packages路徑下看見多了gasp,gasp-0.2.0beta1-py2.6.egg-info,pygame,pygame-1.9.3.dist-info 4個(gè)文件夾
執(zhí)行 復(fù)制教材的腳本,命名為“gasp.py”
from gasp import *begin_graphics()Circle((200, 200), 60)Line((100, 400), (580, 200))Box((400, 350), 120, 100)update_when('key_pressed')end_graphics()運(yùn)行發(fā)現(xiàn)一直報(bào)錯(cuò),
c:/>python gasp.pyTraceback (most recent call last): File "gasp.py", line 1, in <module> from gasp import * File "c:/gasp.py", line 3, in <module> begin_graphics()NameError: name 'begin_graphics' is not defined這個(gè)問題把頭都搞大了。最后在同事的幫助下,發(fā)現(xiàn)跟pygame有關(guān)系。他沒有安裝pygame,報(bào)的錯(cuò)跟我一樣。但是我是已經(jīng)安裝了pygame,也許是版本兼容問題吧。最后只能把gasp.py腳本放到C:/Python27/Lib/site-packages 文件夾才能成功運(yùn)行。 如果有朋友知道是什么原因,請留言,感謝~!
