Not found with Python 3.
You can force the use of python 2 (after installing it)
node-gyp install --python C:\Python27
I am trying to make ionic2 app. But npm is not supporting. It always gives me this error.
Try to install previous version of npm:
npm install npm#5.2 -g
Unfortunatelly, current version(5.3) has a lot of bugs.
I found solution of it. Solution is uninstall node and npm completely from your PC and then re-install it.
to uninstall node and npm completely check this link.

This worked for me:
npm install -g --only=production --save har-schema
Following this question, NPM dependencies can be installed using:
$ npm install --ignore-scripts
Is there a way to mark that a dependency should be installed without running scripts in package.json?
This is because, when I run npm install --ignore-scripts, the dependency is added to package.json. As a result, other users will install the package while running scripts, however I want this certain package to never run scripts.
I could be wrong but I believe its: npm install -ignore-script package-name#version
I'm attempting to install the Ushahidi V3 Client. I've been following the install process up until when I need to build the project from the source repo using npm and gulp - both of which I've had zero experience with. Whenever I run sudo npm install in the project directory, the process runs without complaints. However, when I run npm ls to verify that dependencies have been downloaded, I get a bunch of dependencies listed out as being missing.
How do I get npm to resolve all of these dependencies?
System Details
OS Ubuntu 14.04 (Trusty)
Node JS v0.12.9
NPM v3.5.1
What I've tried
Removing node_modules folder and re-running sudo npm install as referenced in this SO answer for a similar question: npm Gulp dependencies missing, even after running npm install
Uninstalling and reinstalling node and npm
#Strainy, as your research :D
It was a combination of running as sudo and not having the build-essentials.
That's why you should not use sudo npm
Follow these steps:
try npm uninstall. and then try npm install.
Also If it still doesn't work.
Try:
npm install -g npm-install-missing
or
npm-install-missing

I used nvm to download node v0.4.10 and installed npm to work with that version of node.
I am trying to install express using
npm install express -g
and I get an error that express requires node version >= 0.5.0.
Well, this is odd, since I am following the directions for a node+express+mongodb tutorial here that used node v0.4.10, so I am assuming express is/was available to node v0.4.10. If my assumption is correct, how do I tell npm to fetch a version that would work with my setup?
If you have to install an older version of a package, just specify it
npm install <package>#<version>
For example: npm install express#3.0.0
You can also add the --save flag to that command to add it to your package.json dependencies, or --save --save-exact flags if you want that exact version specified in your package.json dependencies.
The install command is documented here: https://docs.npmjs.com/cli/install
If you're not sure what versions of a package are available, you can use:
npm view <package> versions
And npm view can be used for viewing other things about a package too. https://docs.npmjs.com/cli/view
It's quite easy. Just write this, for example:
npm install -g npm#4.6.1
Or:
npm install -g npm#latest // For the last stable version
npm install -g npm#next // For the most recent release
First remove old version, then run literally the following:
npm install express#3.X
or
npm install express#4.X
and for stable or recent
npm install -g npm#latest // For the last stable version
npm install -g npm#next // For the most recent release
In my opinion that is easiest and fastest way:
$ npm -v
4.2.0
$ npm install -g npm#latest-3
...
$ npm -v
3.10.10
you can update your npm package by using this command:
npm install <package_name>#<version_number>
example:
npm install yargs#12.0.2
You can use the following command to install a previous version of an npm package:
npm install packagename#version
I have a general way to solve this type of problems, which could be helpful too, especially when cloning repositories to run them locally, but requires a little more analysis of the versions.
With the package npm-check-updates I verify the versions of the packages (according to the package.json file) that are not declared in their latest available versions, as shown in the figure (https://www.npmjs.com/package/npm-check-updates):
With this information we can verify the update status of the different packages and make decisions as to which packages to upgrade / degrade and which ones do not.
Assuming that we decided to update all the packages as they are listed, we can use the ncu -u command which only modifies your package.json file. Run npm install to update your installed packages and package-lock.json.
Then, depending on the requirements of the repository, we can refine what is needed, installing the specific versions with
npm view <package> versions and npm install <package>#<version>
The easiest way I found: add package name with the version in package.json and then run npm install
"next-seo": "^5.4.0",
"next-themes": "^0.1.1",
"nextjs-progressbar": "^0.0.14",
If you have to install an older version of a package, just specify it
npm install #
For example: npm install express#3.0.0
You can also add the --save flag to that command to add it to your package.json dependencies, or --save --save-exact flags if you want that exact version specified in your package.json dependencies.
The install command is documented here: https://docs.npmjs.com/cli/install
If you're not sure what versions of a package are available, you can use:
npm view versions
And npm view can be used for viewing other things about a package too. https://docs.npmjs.com/cli/view
Use npm config set save-exact=true if you want to install the exact version
