after nodejs update, libhttp_parser.so.2 error

[rolfbakker]

Hi Robert,
I love this project. Based on your work I wrote a nagios-plugin warning me for low pressure in my heating-system, and a daily graph displaying current and set temperature. Thanks!
However, after an update of nodejs and npm, 'easy' ends in an error:
$ easy --access-key=XXXXX --serial=999999 --password=xxxxx status node: error while loading shared libraries: libhttp_parser.so.2: cannot open shared object file: No such file or directory
I run it on a Centos7 server, with:

$ rpm -qa|grep node
nodejs-6.10.3-1.el7.x86_64
nodejs010-runtime-2.1-5.el7.x86_64
nodejs010-http-parser-2.0-6.20121128gitcd01361.el7.x86_64

and

$ rpm -qa|grep npm
npm-3.10.10-1.6.10.3.1.el7.x86_64

The lib is present though:

$ locate  libhttp_parser.so.2
/opt/rh/nodejs010/root/usr/lib64/libhttp_parser.so.2
/opt/rh/nodejs010/root/usr/lib64/libhttp_parser.so.2.0

Can you please advice?
If more info is needed I will be happy to provide it to you.
Thanks,
Rolf

Hoi Rolf,

I'm not familiar with CentOS, but it looks like the nodejs010-* package may be dependencies for Node.js 0.10, which is an outdated version.

What does this return?

$ /usr/bin/env node -v

It ends in the same error:
$ /usr/bin/env node -v
node: error while loading shared libraries: libhttp_parser.so.2: cannot open shared object file: No such file or directory

Hmm, okay, that looks to be pretty broken.

You might try removing everything Node-related and follow the installation instructions here: https://nodejs.org/en/download/package-manager/#enterprise-linux-and-fedora (for Node v6).

After removing (what was strange, because after removing the installscript still reported it was present) and reinstalling, all works fine again.

$ rpm -qa|grep node
nodejs010-runtime-2.1-5.el7.x86_64
nodejs-6.10.3-1nodesource.el7.centos.x86_64
nodesource-release-el7-1.noarch

$ /usr/bin/env node -v
v6.10.3

npm isn't installed now. But do I understand correct that it isn't needed to run ' easy' ?
Thanks for your help!

npm is not required to run easy, but it's still unexpected that it isn't installed alongside Node itself (however, if it works, it works 😉)
