easy_install is not so easy。
這是我最近在學(xué)習(xí)python的一絲體會，好多l(xiāng)ib都無法通過easy_install安裝，比如:
Python Imaging Library (PIL)
只能通過手工安裝方式安裝：
＊download the
pil_1.1.6
＊tar xvf Imaging-1.1.6.tar.gz & chmox +x setup.py
＊python setup.py build
結(jié)果，居然：
_imagingtk.c -o build/temp.linux-i686-2.6/_imagingtk.o
_imagingtk.c:20:16: error: tk.h: No such file or directory
_imagingtk.c:23: error: expected ‘)’ before ‘*’ token
_imagingtk.c:31: error: expected specifier-qualifier-list before ‘Tcl_Interp’
_imagingtk.c: In function ‘_tkinit’:
_imagingtk.c:37: error: ‘Tcl_Interp’ undeclared (first use in this function)
_imagingtk.c:37: error: (Each undeclared identifier is reported only once
_imagingtk.c:37: error: for each function it appears in.)
_imagingtk.c:37: error: ‘interp’ undeclared (first use in this function)
_imagingtk.c:45: error: expected expression before ‘)’ token
_imagingtk.c:51: error: ‘TkappObject’ has no member named ‘interp’
_imagingtk.c:55: warning: implicit declaration of function ‘TkImaging_Init’
error: command 'gcc' failed with exit status 1
tk.h No such file or directory
事實上，tk-dev包我已經(jīng)安裝了，查看setup.py代碼，發(fā)現(xiàn)：
# Library pointers.
#
# Use None to look for the libraries in well-known library locations.
# Use a string to specify a single directory, for both the library and
# the include files. Use a tuple to specify separate directories:
# (libpath, includepath). Examples:
#
# JPEG_ROOT = "/home/libraries/jpeg-6b"
# TIFF_ROOT = "/opt/tiff/lib", "/opt/tiff/include"
#
# If you have "lib" and "include" directories under a common parent,
# you can use the "libinclude" helper:
#
# TIFF_ROOT = libinclude("/opt/tiff")
FREETYPE_ROOT = None
JPEG_ROOT = None
TIFF_ROOT = None
ZLIB_ROOT = None
TCL_ROOT = None
將TCL_ROOT = None 修改成：TCL_ROOT = '/usr/include/tk'，即可
python setup.py build
python setup.py install
成功 ：）
