Python not found as dependency during ' npm jsbin' installation. What is missing?

问题


This question was created from issues I've encountered while trying to install jsbin locally. JGallardo has asked me to create a question from it, because originally I've posted comments in the original Q&A (please follow the link to see what it was about).

Update: Since the Windows tag has been removed by reviewers, let me note that I am having the issues on a Windows 7 machine.

The command npm install jsbin don't work for me - it throws an error I don't understand: "npm ERR! Error: getaddrinfo EAGAIN npm ERR! at errnoException (dns.js:37:11) npm ERR! at Object.onanswer [as oncomplete] (dns.js:124:16)"

I've set up a proxy server, which is required in my case as I found: npm config set proxy=http://servername:port. Now it is fetching files, when I call npm install jsbin into the "c:\users\myuser\AppData\Roaming\npm-cache" directory - but it is running very long. Now it is saying "can't find python executable" - do you know which dependency this is? How can I install the python package if that is required?

After getting the error above, I have also tried to install npn install python before running npn install jsbin. It also did not work, I am still getting the error "Error: Can't find Python executable "python", you can set the PYTHON env variable."

Can you help to get jsbin installed locally? Why can't npm find the python package although it seems to be installed?

N.B. I now have also installed the official Python interpreter from the official source and verified that it is available through the pathenvironment variable:

Your environment has been set up for using Node.js 0.10.12 (x64) and npm.

C:\>python
Python 3.3.2 (v3.3.2:d047928ae3f6, May 16 2013, 00:06:53) [MSC v.1600 64 bit (AMD64)] on win32
Type "help", "copyright", "credits" or "license" for more information.
>>>

Also, I've set up the PYTHONenvironment variable to the path C:\Python33 where the python system was installed to.

The error I am getting is:

gyp ERR! configure error
gyp ERR! stack Error: spawn ENOENT
gyp ERR! stack     at errnoException (child_process.js:980:11)

I could not find out why NPN wasn't installing python, but then I tried it with a different installer, choco (or Chocolatey), which succeeded.

Steps are:

  1. Install Chocolatey. See Chocolatey website for instructions
  2. Open administrator console, then do the following:

C:\WINDOWS\system32>choco install python

!!ATTENTION!!
The next version of Chocolatey (v0.9.9) will require -y to perform
  behaviors that change state without prompting for confirmation. Start
  using it now in your automated scripts.

  For details on the all new Chocolatey, visit http://bit.ly/new_choco
Chocolatey (v0.9.8.33) is installing 'python' and dependencies. 
By installing you accept the license for 'python' and each dependency you are installing.
