安装错误认为pythonpath是空的

我试图在这里安装scikits.nufft包我下载zip文件,解包并cd到目录。 它包含一个setup.py文件,所以我运行

python setup.py install 

但它给了我以下与我的PYTHONPATH相关的错误

 sudo python setup.py install sudo: unable to resolve host Lenovo /usr/local/lib/python2.7/dist-packages/distribute-0.6.31-py2.7.egg/setuptools/command/install_scripts.py:3: UserWarning: Module dap was already imported from None, but /usr/lib/python2.7/dist-packages is being added to sys.path from pkg_resources import Distribution, PathMetadata, ensure_directory running install Checking .pth file support in /usr/local/lib/python2.7/site-packages/ /usr/bin/python -E -c pass TEST FAILED: /usr/local/lib/python2.7/site-packages/ does NOT support .pth files error: bad install directory or PYTHONPATH You are attempting to install a package to a directory that is not on PYTHONPATH and which Python does not read ".pth" files from. The installation directory you specified (via --install-dir, --prefix, or the distutils default setting) was: /usr/local/lib/python2.7/site-packages/ and your PYTHONPATH environment variable currently contains: '' Here are some of your options for correcting the problem: * You can choose a different installation directory, ie, one that is on PYTHONPATH or supports .pth files * You can add the installation directory to the PYTHONPATH environment variable. (It must then also be on PYTHONPATH whenever you run Python and want to use the package(s) you are installing.) * You can set up the installation directory to support ".pth" files by using one of the approaches described here: http://packages.python.org/distribute/easy_install.html#custom-installation-locations Please make the appropriate changes for your system and try again. 

似乎认为path是空的,但当我检查我的path时,

 echo $PYTHONPATH /usr/local/lib/python2.7/site-packages:/home/david/PYTHON 

有谁知道为什么它可能认为path是空的? 或者有什么其他的想法可能在这里是错的。 谢谢,戴夫

上面的Aya的评论后,我发现类似的解决问题,并得到它通过添加运行

 Defaults env_keep += "PYTHONPATH" 

到sudoers文件。 Ta,Dave

对于想避开sudo的用户,请在本地用户下安装:

 PYTHONPATH=~/local/lib/python2.7/site-packages/ python ./distribute_setup.py
