node-inspector fail to install.

From the logs npm ERR! Failed at the v8-profiler@5.2.11 install script 'node-pre-gyp install - -fallback-to-build'.

I am using Windows7 64bit npm@2.11.3 node version v0.12.7

I have done my due diligence with Google but no working solution so far. Do share it here if you have a solution to this problem.

node install node-inspector@0.7.4 -g

node-debug src/app.js

To launch it

there is no space node -debug

It's really difficult to tell in the video that there's no space between "node" and "-debug", because it wraps to another line.

Additionally, node-inspector requires python 2.7, therefore if you have python 3+ installed, you must install python 2.7 and update the system environment variables to include python 2.7 and not python 3.

Or you can use the --python option to use a different version of Python when installing a module:

npm install node-inspector@0.7.4 -g --python=C:\Python27\python.exe

Or wherever Python 2.7 is installed...

TL;DR : npm install -g node-inspector@0.7.4

Hi There,

I am on windows 8 and had the same problem.

I found the answer here: https://github.com/node-inspector/node-inspector/issues/516

If you scroll down, you see Tiendq installs an older version of it: v0.7.4.

You can do this with the command: npm install -g node-inspector@0.7.4

Note, I wasn't sure if I needed to install python, because I was getting errors relating to Python as well, but I went ahead and did that, and included python in my system PATH variable.

To install python with the help of Treehouse: https://teamtreehouse.com/library/setting-up-a-local-python-environment/installing-python-and-python-libraries-locally/installing-python-3-on-windows .

and you can simply find out how to adjust your system path with a Google search
