我不想使用简单安装、站点包中的符号链接或pythonpath安装python模块。
所以,我正在尝试一些我想要的系统范围内的东西,然后任何应用程序安装都在本地完成。注意,这里只需要根密码一次。
首先创建一个符号闪烁…/pythonx.y/site-packages/mymodules->/home/me/lib/python_related
所以,我创建了一个名为
/home/me/lib/python_related/
在那里:
/home/me/lib/python_related
/home/me/lib/python_related/__init__.py
/home/me/lib/python_related/django_related/
/home/me/lib/python_related/django_related/core
/home/me/lib/python_related/django_related/core/Django1.0
/home/me/lib/python_related/django_related/core/Django1.1
/home/me/lib/python_related/django_related/core/mycurrent_django -> Django1.1/django
/home/me/lib/python_related/django_related/apps
/home/me/lib/python_related/django_related/apps/tagging
/home/me/lib/python_related/django_related/apps/tagging/django-tagging-0.2
/home/me/lib/python_related/django_related/apps/tagging/django-tagging-0.3
/home/me/lib/python_related/django_related/apps/tagging/mycurrent_tagging -> django-tagging-0.3
现在,以下是内容:
/home/me/lib/python_related/__init__.py
==========================================
import sys, os
# tell us where you keep all your modules and this didn't work as it gave me
# the location of the site-packages
#PYTHON_MODULE_PATH = os.path.dirname(__file__)
PYTHON_MODULE_PATH = "/home/me/libs/python_bucket"
def run_cmd(cmd):
"""
Given a command name, this function will run the command and returns the output
in a list.
"""
output = []
phdl = os.popen(cmd)
while 1:
line = phdl.readline()
if line == "":
break
output.append(line.replace("\n", ""))
return output
def install():
"""
A cheesy way of installing and managing your python apps locally without
a need to install them in the site-package. All you'd need is to install
the directory containing this file in the site-package and that's it.
Anytime you have a python package you want to install, just put it in a
proper sub-directory and make a symlink to that directory called mycurrent_xyz
and you are done. (e.g. mycurrent_django, mycurrent_tagging .. etc)
"""
cmd = "find %s -name mycurrent_*" % PYTHON_MODULE_PATH
modules_to_be_installed = run_cmd(cmd)
sys.path += modules_to_be_installed
install()
=======================================================
现在,在任何新的python项目中,只需导入mymodules,就可以使用适当的符号链接将上面目录中的任何应用程序拉进来。这样,您就可以拥有多个应用程序副本,只需将mycurrent xyz用于您要使用的应用程序。
现在有个问题。这是个好办法吗?
