在嘗試編寫今天使用PIL的

Python腳本的過(guò)程中,我發(fā)現(xiàn)我似乎沒(méi)有在我的本地計(jì)算機(jī)上使用它(OS X 10.5.8,默認(rèn)2.5 Python安裝).

所以我跑：

easy_install --prefix=/usr/local/python/ pil

它有點(diǎn)抱怨/usr/local/python/lib/python2.5/site-packages尚未存在,所以我創(chuàng)建它,然后再試一次,得到這個(gè)：

TEST FAILED:

/usr/local/python//lib/python2.5/site-packages

does NOT support .pth files error: bad

install directory or PYTHONPATH

You are attempting to install a

package to a directory that is not on

PYTHONPATH and which Python does not

read “.pth” files from. The

installation directory you specified

(via –install-dir, –prefix, or the

distutils default setting) was:

06001

and your PYTHONPATH environment

variable currently contains:

06002

好吧,公平 – 我沒(méi)有做任何事情來(lái)設(shè)定路徑.所以我給?/ .bash_profile添加了一個(gè)快速行：

PYTHONPATH=”$PYTHONPATH:/usr/local/python/lib/python2.5″

并采購(gòu)它,然后再試一次.

相同的錯(cuò)誤消息.

考慮到PYTHONPATH顯然是固定的,這有點(diǎn)好奇;我可以回顯$PYTHONPATH并返回：/usr/local/python/lib/python2.5.我決定從里面查看包含路徑的樣子：

import sys

print "\n".join(sys.path)

產(chǎn)量：

/System/Library/Frameworks/Python.framework/Versions/2.5/lib/python25.zip

/System/Library/Frameworks/Python.framework/Versions/2.5/lib/python2.5

/System/Library/Frameworks/Python.framework/Versions/2.5/lib/python2.5/plat-darwin

/System/Library/Frameworks/Python.framework/Versions/2.5/lib/python2.5/plat-mac

/System/Library/Frameworks/Python.framework/Versions/2.5/lib/python2.5/plat-mac/lib-scriptpackages

/System/Library/Frameworks/Python.framework/Versions/2.5/Extras/lib/python

/System/Library/Frameworks/Python.framework/Versions/2.5/lib/python2.5/lib-tk

/System/Library/Frameworks/Python.framework/Versions/2.5/lib/python2.5/lib-dynload

/Library/Python/2.5/site-packages

/System/Library/Frameworks/Python.framework/Versions/2.5/Extras/lib/python/PyObjC

/usr/local / python / yadda / yadda明顯缺失.

不知道我應(yīng)該在這做什么.如何讓python將此位置識(shí)別為包含路徑？

UPDATE

正如Sven Marnach所說(shuō),我忽略了出口PYTHONPATH.我已經(jīng)糾正了這個(gè)問(wèn)題,現(xiàn)在看到它出現(xiàn)在我從Python中打印出sys.path時(shí).但是,我仍然得到了上面提到的TEST FAILED錯(cuò)誤消息,只是我的新PYTHONPATH環(huán)境變量.

所以,我嘗試將它從/usr/local/python/lib/python2.5更改為/usr/local/python/lib/python2.5/site-packages,導(dǎo)出并再次運(yùn)行相同的easy_install命令.這導(dǎo)致一個(gè)全新的結(jié)果,起初看起來(lái)像成功(但不是)：

PIL 1.1.7 SETUP SUMMARY

--------------------------------------------------------------------

version 1.1.7

platform darwin 2.5.1 (r251:54863, Sep 1 2010, 22:03:14)

[GCC 4.0.1 (Apple Inc. build 5465)]

--------------------------------------------------------------------

--- TKINTER support available

--- JPEG support available

--- ZLIB (PNG/ZIP) support available

*** FREETYPE2 support not available

*** LITTLECMS support not available

--------------------------------------------------------------------

To add a missing option, make sure you have the required

library, and set the corresponding ROOT variable in the

setup.py script.

To check the build, run the selftest.py script.

zip_safe flag not set; analyzing archive contents...

No eggs found in /var/folders/XW/XWpClVq7EpSB37BV3zTo+++++TI/-Tmp-/easy_install-krj9oR/PIL-1.1.7/egg-dist-tmp--Pyauy (setup script problem?)

再次,這看起來(lái)不錯(cuò),但是當(dāng)我去運(yùn)行我的腳本時(shí)：

Traceback (most recent call last):

File “checkerboard.py”, line 1, in

import Image, ImageDraw ImportError: No module named Image

當(dāng)我使用find查看/usr/local / python /下的內(nèi)容時(shí),我得到：

./lib ./lib/python2.5

./lib/python2.5/site-packages

./lib/python2.5/site-packages/site.py

./lib/python2.5/site-packages/site.pyc

所以…沒(méi)有任何模塊外觀(我假設(shè)site.py和site.pyc是元數(shù)據(jù)或幫助腳本).安裝在哪里？

我注意到這個(gè)：

To check the build, run the

selftest.py script.

但是真的不知道那是什么.

我還注意到“沒(méi)有發(fā)現(xiàn)雞蛋”的消息.這些提示中的任何一個(gè)？
