安装错误认为pythonpath为空 [英] install error thinks pythonpath is empty

问题描述

我正在尝试在以下位置安装scikits.nufft软件包此处 我下载了zip文件，将其解压缩并cd到目录中.它包含一个setup.py文件，因此我运行

I am trying to install the scikits.nufft package here I download the zip file, unpack and cd to the directory. It contains a setup.py file so I run

python setup.py install

但是它给我以下与我的PYTHONPATH相关的错误

but it gives me the following error related to my PYTHONPATH

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

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, i.e., 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.

似乎认为路径是空的，但是当我检查路径时，

It seems to think the path is empty but when I check my path I get,

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

有人知道为什么它会认为路径为空吗?或对此处可能存在的问题有其他任何想法. 谢谢， 戴夫

Does anyone know why it might think the path is empty?? or have any other ideas as to what may be wrong here. Thanks, Dave

推荐答案

在上述Aya评论之后，我发现了类似的已解决问题

After Aya's comment above I found similar resolved problem here and got it to run by adding

Defaults    env_keep += "PYTHONPATH"

到sudoers文件. ， 戴夫

to the sudoers file. Ta, Dave
