node-gyp: gyp ERR! cannot load shared libpython2.7.so.1.0

[deng....@gmail.com]

Hi group:

I am trying to build the hello world c++ addon for node js. Both node.js and node-gyp seem have been installed successfully into a redhat linux. However when I ran "node-gyp configure", it gave the following error. I failed to get any insightful information by gooling as well as from the wiki page. Can you please kindly advise?

Thanks in advance.

~/examples/node.js/my_node_addon-1[13:14]% node-gyp configure

gyp info it worked if it ends with ok

gyp info using node-gyp\@0.10.10

gyp info using node\@0.10.18 | linux | x64

gyp ERR! configure error

gyp ERR! stack Error: Command failed: python: error while loading shared libraries: libpython2.7.so.1.0: cannot open shared object file: No such file or directory

gyp ERR! node -v v0.10.18

gyp ERR! node-gyp -v v0.10.10

gyp ERR! not ok

But when I run python alone it loads the shared lib just fine:

~/examples/node.js/my_node_addon-1[13:14]% python -V

Python 2.7.3

No, the shared libraries come in a python-dev package, not the regular
executables.

Search the development libraries for python, install them and you will
not have this issue anymore.

Thanks Jose. 

But I built the python from source and had a customized installation. And libpython2.7.so.1.0 is presented in the following:$PYTHONPATH as well as $LD_LIBRARY_PATH. Does node or node-gyp search a rather different environment virable for shared libraries?

I also specifed the binding.gyp as below, but it seems still not picking up.

{

    'targets': [

        {

            'target_name': 'hello',

            'sources': [ 'src/hello.cc' ],

            'include_dirs': ['/path/to/my/include'],

            'link_settings': {

                'library_dirs': [

                    '/path/to/my/libpython2.7.so.1.0'

                ]

            }

        }

    ]

}

Hi group-

Finally, after 2 days of consecutive tracing and debugging, I had this sorted. However, I am not sure if this is due to my customized installation of Python. I updated the code below in ~node_modules/node-gyp/lib/configure.js (changed original as in commented line 93 to 94:

93     // var env = { TERM: 'dumb', PATH: process.env.PATH};

94     var env = process.env

I will truly appreciate if any node.js experts in the group can help with a rational with the above change?

Thanks again

Feng

v0.13.0 of node-gyp should have this fixed. Thanks for reporting!
