In the morning every thing was working but just start happening now in my current project
If i create a new project then it runs perfectly.
I am very new in ionic so please suggest some solution

Runtime (Node Module ABI) version 51 means it's an Electron environment, which node-sass doesn't directly support.

Docusaurus build fails with "sharp" module issue

Upon yarn build my projects fails to build. I've tried recommended options, but nothing works and error returns every-time. The project works upon using yarn start, just the build doesn't work

Module did not self-register. Electron app using a custom build c++ node module compiled with cmake-js

Working on a project. Built a C++ module for node, compiled it with cmake. I tried using the module in my main electron app but it errors out.
Reproduced it with a minimal repo here: https://github.com/Aerrus/electronMinimal
App threw an error during load

Saw a lot of threads already about rebuilding it, making sure the node version when I built it was the same, and so on. None of them changed anything.
If you're using electron v4.0
take a look at this. I hope it helped because that's how I solved the problem
adding delay hook to cmakelist using cmake-js

pm2 'cluster' mode fail to load LD_LIBRARY_PATH

i'm installing a npm package ccap to generate CAPTCHA. Because it's a c++ add on and requires gcc 4.8 +,i met some problems while installing it.
I compiled gcc 4.9.4 and installed ccap successfully on my development machine.
However ,i met this wield problem when i try to start my application (without pm2).
Error: /usr/lib64/libstdc++.so.6: version `CXXABI_1.3.8' not found (required by /home/jwb/ccapDemo/node_modules/ccap/build/Release/hcaptha.node)

I googled a lot and got it fixed by setting following linux enviroment variable in .bash_profile.
export LD_LIBRARY_PATH=/home/jwb/gcc-4.9.4/lib64:$LD_LIBRARY_PATH
Now it seems like working ,but when i try to start my demo in PM2 cluster mode,the same problem occured.
I also tried pm2 fork mode,and it worked just fine.
So i figured maybe LD_LIBRARY_PATH can not be found in PM2 cluster mode.Then i printed process.env and found LD_LIBRARY_PATH.
So i think this problem is somehow related to PM2 cluster mode ,but i don't know how to fix it.
I do not have root authority and can not just update /usr/lib64/libstdc++.so.6 to a higher version. Have someone met same problem ?How should i solve it?

OS : Red Hat 6
gcc : 4.9.4 (default gcc version is 4.4.7)

ember-cli gives "Unexpected end of JSON input"

I have recent node (7.1.0) and npm (4.0.2) installations on macOS Sierra 10.12.1 with Xcode 8.1. The installation of the ember-cli package seems to work fine apart from two warnings:
08:51 $ npm install -g ember-cli

npm WARN deprecated minimatch#2.0.10: Please update to minimatch 3.0.2 or higher to avoid a RegExp DoS issue

But when I call ember it always gives me the following error:
08:52 $ ember --help
module.js:593
throw err;

How can I get ember to run correctly?

Cannot load node.js native addon when built with node-gyp, but it works when built with Visual Studio

I've written a native addon for node.js, compiled it with MSVC++ without node-gyp, and used it successfully on the node REPL and in an application. I'm using x64 node and compiling an x64 addon. I'm trying to get the thing to build with node-gyp. I've gotten node-gyp to generate a Visual Studio solution and compile it, but the addon that comes out does not work. The only error I get is this:
Error: The specified procedure could not be found.

When I run a script that tries to load the addon, I get this:

process.dlopen(filename, module.exports);

I've learned that dlopen has something to do with loading dynamic libraries on Linux, but can't find any useful information relevant to node (in particular, on Windows.). This addon requires some third-party dlls, but they are on my path, and again, the addon works fine when I compile it without node-gyp.
What do I need to do to figure out how to make this work?
It turned out that the problem lay in my use of the NODE_MODULE macro. I had something like this:
NODE_MODULE(SomeAddonName, Init)
But my binding.gyp had this:
"target_name": "totallyDifferentName",
It turns out that target_name in binding.gyp must be the same as the module name (the first argument to NODE_MODULE).
Thanks to #TooTallNate for helping me with this!
