问题 I downloaded a package (called pysolr 2.0.15) to my computer to be used with Haystack. The instructions asks me to add pysolr to my PYTHONPATH. What exactly does that mean?

Thanks for the help! 回答1: The pythonpath tells python were to look for modules, for example you might have written a library that you want to use in several applications and

I am using centos linux. I had python 2.6 with django and now i upgraded to python 2.7. Python 2.6 is located in /usr/lib/python2.6. Python 2.7 is located in /usr/local/lib/python2.7. They both have site-packages directory and they both contain django 1.2. If i run python i get the 2.7 version. My problem is that if try to import django i get ImportError: No module named django I am not sure where is my PYTHONPATH defined and if this is what i need to change. anyone ? i ended up making a symbolic link to the 2.6 site-packages directory. jcollado To check your path, you can use the following

Effect of using sys.path.insert(0, path) and sys.path(append) when loading modules

问题 I was recently having a problem with a python ImportError, where the module was found when running on my local computer but not found on the CI server. I solved this problem by swapping sys.path.append(path) in my script with sys.path.insert(0, path) where path is the string module location. Since this is my module and not an installed package (related question), why does the order of paths fix this problem? 回答1: Because python checks in the directories in sequential order starting at the

All works well, I seldom have the need to run manage.py but am trying to use the new staticfiles app and am running into problems. python manage.py collectstatic Traceback (most recent call last): File "manage.py", line 2, in <module> from django.core.management import execute_manager ImportError: No module named core

adding directory to sys.path /PYTHONPATH

由 五迷三道 提交于 2019-11-26 19:40:49
I am trying to import a module from a particular directory. The problem is that if I use sys.path.append(mod_directory) to append the path and then open the python interpreter, the directory mod_directory gets added to the end of the list sys.path. If I export the PYTHONPATH variable before opening the python interpreter, the directory gets added to the start of the list. In the latter case I can import the module but in the former, I cannot. Can somebody explain why this is happening and give me a solution to add the mod_directory to the start, inside a python script ? Ned Deily This is
