I use up-to-date Debian testing (wheezy), amd64 architecture. I downloaded, compiled and installed Python 3.3.0 alpha 3 (from python.org) using "altinstall". Debian wheezy comes with python3.2 (and 2.6 and 2.7). I installed the Debian package "python3-bs4" (BeautifulSoup4 for Python3). Note: Debian uses eggs.
Python3.3a3 cannot find module bs4. Python3.2 can find the module. Here is a session with Python 3.3: > python3.3 Python 3.3.0a3 (default, May 5 2012, 11:30:48) [GCC 4.6.3] on linux Type "help", "copyright", "credits" or "license" for more information. >>> import bs4 Traceback (most recent call last): File "<stdin>", line 1, in <module> File "<frozen importlib._bootstrap>", line 1012, in _find_and_load ImportError: No module named 'bs4' >>> Here is what I have tried: 1. Put bs4.pth in /usr/local/lib/python3.3/site-packages. This file should contain the line: /usr/lib/python3/dist-packages This works. 2. At the start of each Python program using bs4: import sys sys.path.append('/usr/lib/python3/dist-packages') import bs4 This works. 3. In the Python 3.3 source code, do ".configure" then edit Modules/Setup to contain SITEPATH=:/usr/lib/python3/dist-packages Finish compiling and altinstalling python. "import bs4" works. The last is the best because I only have to do it once. Next I tried numpy. It is installed from Debian package "python3-numpy". If I compile Python 3.3 _without_ the change in (3) above, I get: > python3.3 Python 3.3.0a3 (default, May 8 2012, 14:30:18) [GCC 4.6.3] on linux Type "help", "copyright", "credits" or "license" for more information. >>> import numpy Traceback (most recent call last): File "<stdin>", line 1, in <module> File "<frozen importlib._bootstrap>", line 1012, in _find_and_load ImportError: No module named 'numpy' >>> which is not a surprise. If I compile and install Python 3.3 _with_ the change in (3) above, I get: > python3.3 Python 3.3.0a3 (default, May 8 2012, 14:43:28) [GCC 4.6.3] on linux Type "help", "copyright", "credits" or "license" for more information. >>> import numpy Traceback (most recent call last): File "<stdin>", line 1, in <module> File "<frozen importlib._bootstrap>", line 1015, in _find_and_load File "<frozen importlib._bootstrap>", line 634, in load_module File "<frozen importlib._bootstrap>", line 294, in module_for_loader_wrapper File "<frozen importlib._bootstrap>", line 522, in _load_module File "/usr/lib/python3/dist-packages/numpy/__init__.py", line 137, in <module> from . import add_newdocs ImportError: cannot import name add_newdocs >>> "add_newdocs.py" is present in the numpy directory. The "import numpy" works for the Debian python 3.2. What is the problem? -- http://mail.python.org/mailman/listinfo/python-list
