Thank you for the excellent training session on using ipython in galaxy.

However when I tried to repeat it on my desktop I had an error doing the step
Change directory into: lib/galaxy/web/proxy/js/
$ cd lib/galaxy/web/proxy/js/
Then install the node proxy with “npm”:
$ npm install .

I get:
npm http GET https://registry.npmjs.org/sqlite3/3.0.2
npm http 304 https://registry.npmjs.org/sqlite3/3.0.2
npm http GET https://registry.npmjs.org/nan/1.3.0
npm http 304 https://registry.npmjs.org/nan/1.3.0

> sqlite3@3.0.2 install /home/christian/galaxy/lib/galaxy/web/proxy/js/node_modules/sqlite3
> node-pre-gyp install --fallback-to-build

/usr/bin/env: node: No such file or directory
npm WARN This failure might be due to the use of legacy binary "node"

System Information:
Galaxy master revision:6f53676f482634212bac512ec91dbf24e4afacff
(also tried against today's dev)

OS:
Distributor ID:    Ubuntu
Description:    Ubuntu 14.04.2 LTS
Release:    14.04
Codename:    trusty

npm version: 1.3.10

Which is rather strange as these are all exactly the same as in the Virtual machine used.

Any one have any ideas?

Thanks in advance
Christian

PS. Below is the content of: /usr/share/doc/nodejs/README.Debian
nodejs for Debian
=================

packaged modules
----------------

The global search path for modules is
/usr/lib/nodejs

Future packages of node modules will use that directory,
so it should be used wisely.


user modules
------------

Node looks for modules in ./node_modules directory first;
please read node#modules documentation carefully for more information.

Node does not look for modules in /usr/local/lib/node_modules,
where npm put them.
Please read npm-link(1) of npm package, to understand how to properly
use npm-installed modules in a project.

Note that require.paths is not supported in future node versions.
See also node(1) for more information about NODE_PATH.


nodejs command
--------------

The upstream name for the Node.js interpreter command is "node".
In Debian the interpreter command has been changed to "nodejs".

This was done to prevent a namespace collision: other commands use
the same name in their upstreams, such as ax25-node from the "node"
package.

Scripts calling Node.js as a shell command must be changed to instead
use the "nodejs" command.
