python 3.x - assertionerror with python3 and virtualenv -


in ubuntu lucid,i have python2.6 default.i wanted install python 3.3.1.

i extracted python-3.3.1.tar.bz2 home folder sothat /home/me/python-3.3.1 contains files.then per readme did

./configure make make test sudo make install

this created executable named python in /home/me/python-3.3.1 folder.

also, nowi have several python3* files in /usr/local/bin directory.

among them ,

python3 link executable,

python3.3 executable,

python3.3m executable.

i wanted create virtualenv python3 , tried following

sudo virtualenv envpy331 --distribute --no-site-packages --python=/home/me/python-3.3.1/python

this produced assertionerror

file "/usr/local/lib/python2.6/dist-packages/virtualenv-1.8.2-py2.6.egg/virtualenv.py", line 2471, in <module>     main()   file "/usr/local/lib/python2.6/dist-packages/virtualenv-1.8.2-py2.6.egg/virtualenv.py", line 942, in main     never_download=options.never_download)   file "/usr/local/lib/python2.6/dist-packages/virtualenv-1.8.2-py2.6.egg/virtualenv.py", line 1043, in create_environment     site_packages=site_packages, clear=clear))   file "/usr/local/lib/python2.6/dist-packages/virtualenv-1.8.2-py2.6.egg/virtualenv.py", line 1207, in install_python     copy_required_modules(home_dir)   file "/usr/local/lib/python2.6/dist-packages/virtualenv-1.8.2-py2.6.egg/virtualenv.py", line 1159, in copy_required_modules     dst_filename = change_prefix(filename, dst_prefix)   file "/usr/local/lib/python2.6/dist-packages/virtualenv-1.8.2-py2.6.egg/virtualenv.py", line 1134, in change_prefix     (filename, prefixes) assertionerror: filename /home/me/python-3.3.1/lib/os.py not start of these prefixes: ['/usr/local']

what need correct this? need remove python3 installation ,or need reconfigure prefix=/usr/local ? , again run install?

you've installed it. point installed python3. try this:

virtualenv envpy331 --python=/usr/local/bin/python3.3

running rails generate controller foo home results in: class foocontroller < application controller def home end end (there's nothing on line in actual file, blank line) is there purpose blank line? it's common use newline indicate end of line, last line. many editors (like vi, use) add in newline silently. consensus text files (especially in unix world) should end in newline, , there have been problems historically if wasn't present. why should text files end newline? the tool used count lines in file "wc" counts newlines in file, without trailing newline show 3 instead of 4. it improves readability of templates used in generator. consider: https://github.com/rails/rails/blob/master/railties/lib/rails/generators/rails/controller/templates/controller.rb to remove trailing newline, template have last line of: end<% end -%> instead of: end <% end -%> that seems less readable me. the discussion below refers ...
