When I try to install pg module via npm I get the following errors:

Why Pyhton is nedded?

[brianc]

Python is used in the build system node uses to compile 3rd party C/C++ add ons (node-waf & node-gyp).

node-postgres is supposed to continue to install even if its internal compilation fails because it provides a production quality pure-javascript client. Recently another C/C++ addon got added as a dependency for an obscure feature and has been failing to compile on windows breaking the install process. I need to make the 3rd party add-on an optional dependency. Not having access to a windows box its hard for me to test...but I do have a fix in mind & will try to publish a version for you to test later today. Sorry for the headache!

[tetri]

I checked that the node-gyp requires Python 2.7.3 and I have version 3.3.2 which is not supported... I'll do some tests and if successful I'll let you know...

If you need some help, I'm available...

[brianc]

Thanks @tetri. Sorry for not pushing a version out yesterday...I'm gonna try to get to it today.

[brianc]

I pushed a version making the dependency optional. This should fix your install issue.

[tetri]

Sorry @brianc, but the installation still does not work due to the dependence of the ref module, which in turn depends on node-gyp module... I tested the installation in a completely clean environment

[brianc]

What error are you getting?

[tetri]

I'm having the same error that I reported in nodejs/node-gyp#296.
I believe that the most serious problem is the module node-gyp... You can keep this issue closed.

Ditto for me: nodejs/node-gyp#312

[brianc]

Hey, if you don't use the native bindings (I don't either!) then you can use this: https://github.com/brianc/node-postgres-pure

skip the pesky compile step all together.

[DrYSG]

Please excuse this simple (klutz) question. I tried the npm install on postgres-pure, I got the error below. I assume I need to get GnuMake and add it to the path. But just to make sure, is this the MAKE that you want me to install?
Are there other WARNs or things in this npm install that indicate deeper issues?

The npm install of the pure version is now working find for me (I have no idea what changed in the meantime since my last letter): https://github.com/brianc/node-postgres-pure, I am also really like the API and enjoy working with it. I will tell you how it works with PostGIS

BTW( any idea what the warnings are about?)

@DrYSG

[brianc]

Not sure about that warning - it's not related to node-postgres. Glad it's working for you!!
