Under python2.7, I was always able to install Twisted 11.0.0, no problem. Under pypy 1.6, never (but I am not sure if 11.1.0 is supposed to fix it or not). I am running this on Ubuntu 10.04 LTS.Python 2.7 was manually installed (compiled the actual packages from source, not sure if that makes a difference), Will try on a different laptop with Ubuntu 11.10 to see if at least the default python2.7 works there...give me a second...

Sorry :-(

Did you have these errors under the prerelease as well? Under 11.0?

Followup: failed to install with the regular default python (2.6) interpreter on the 10.04 box as well, exact same error. So it doesn't seem to be related to my custom compiled install of 2.7 on that box. Would be good to see if others get the same error on the current Ubuntu 10.04 LTS release.... Jacek

python -m easy_install is just a way to use easy_install as a library, instead of invoking the easy_install shell command (which is problematic, since on some machines I have up to 4 different versions of Python: 2.6, 2.7, PyPy, Jython). if I use easy_install directly, I get the exact same error: sudo easy_install -U Twisted [sudo] password for jacekf: Searching for Twisted Reading http://pypi.python.org/simple/Twisted/ Reading http://www.twistedmatrix.com Reading http://twistedmatrix.com/products/download Reading http://twistedmatrix.com/ Reading http://tmrc.mit.edu/mirror/twisted/Twisted/9.0/ Reading http://twistedmatrix.com/projects/core/ Reading http://tmrc.mit.edu/mirror/twisted/Twisted/8.1/ Reading http://tmrc.mit.edu/mirror/twisted/Twisted/8.2/ Reading http://tmrc.mit.edu/mirror/twisted/Twisted/10.0/ Best match: Twisted 11.1.0 Downloading http://pypi.python.org/packages/source/T/Twisted/Twisted-11.1.0.tar.bz2#md5=...

Under python2.7

*sudo python2.7 -m easy_install -U twisted* [snip] * File "setup.py", line 103, in <module>* * File "setup.py", line 74, in main* * File "setup.py", line 31, in getExtensions* * File "twisted/topfiles/setup.py", line 21, in <module>* *ImportError: cannot import name _isCPython*

"easy_install -U twisted" isn't something we ever test or claimed to support. I don't recall anyone ever asking for support for it either. We do test "easy_install <local twisted tarball filename>" and that works, at least on Python 2.5, on Twisted 11.1. We don't test it on any other Python version.

...

Under PyPy, same errors as before:

*pypy -m easy_install -U twisted* [snip] * File "/home/jacekf/bin/pypy-1.6/site- packages/distribute-0.6.19-py2.7.egg/setuptools/sandbox.py", line 32, in <lambda>* * {'__file__':setup_script, '__name__':'__main__'}* * File "setup.py", line 103, in <module>* * File "setup.py", line 45, in main* *ImportError: cannot import name 'copyright'*

Apart from the same comments about -U above, I don't recall this error on PyPy ever being reported. The install errors we fixed had to do with extension compilation, not a failure to import the name 'copyright'.

Please file tickets for issues you encounter or features you'd like supported. For these, the testing path likely involves setting up a new BuildSlave in the appropriate environment, so if you can donate hardware to run these slaves, that would help out a lot. Otherwise we're not likely to be able to test the configurations, so they won't be supported.

Thanks, Jean-Paul

Sorry, I am just a lonely developer with no funds for extra slaves :-( My interest in Twisted is personal, not work-related (although that may change one day) Cheers Jacek On Fri, Nov 18, 2011 at 2:51 PM, wrote:

if I use easy_install directly, I get the exact same error:

It's the "-U" I was trying to highlight.

And contribute a host to run a build slave? :)
