Fails to npm install nanomsg

Question

I try to install nanomsg on a linux machine so I do

npm install nanomsg --python=python2.7

I use --python=python2.7 option, because I have two different versions of python. However that command fails with this kind of error message

make: Entering directory `/qt_home/{my_username}/node_modules/nanomsg/build'
  CC(target) Release/obj.target/nanomsg/deps/nanomsg/src/aio/ctx.o

I searched about this on the internet, but couldn't find anything helpful. I have found this link so far, but it didn't help me.

My node js version is 6.2.2 and npm version is 2.14.7.

Any ideas or suggestions?

Answer 1

Have you tried, using sudo for the install. Sometimes it requires it for certain parts.

sudo npm install nanomsg --python=python2.7

Also im not too familiar with Python but can you add the direct path instead of python2.7

sudo npm install nanomsg --python=/usr/bin/python2.7

Answer 2

The error message

cc1: error: unrecognized command line option "-Wno-maybe-uninitialized"

indicate that your compiler doesnot support the option -Wno-maybe-uninitialized .

The compiler option use to build de nanomsg librairie are defined in linux.gypi .

'cflags': [
'-O3', '-Wall', '-Wextra', '-Wno-sign-compare', '-Wno-strict-aliasing',
'-Wno-unused', '-Wno-char-subscripts', '-Wno-maybe-uninitialized',
'-Wno-implicit-function-declaration', '-lpthread',
],

In order to use the nanomsg configure to build it according your compiler, you could proceed like this :

git clone https://github.com/nanomsg/nanomsg
cd nanomsg
./configure
cmake .
make 
sudo make install
sudo cp /usr/local/lib/pkgconfig/naming.pc /usr/local/lib/pkgconfig/libnaming.pc 

Next you should be able to run :

npm install nanomsg --use_system_libnanomsg=true
