I am not able to install using npm about hnswlib-node

Think I figured it out, you need to install Visual Studio.

@lucky-9 As indicated in the error message, to install node-gyp on which hnsw-node depends, you need to install the build tools: https://github.com/nodejs/node-gyp#on-windows

I'm also getting the same issue.

@jaymehta-ce install visual studio build tool with c++ env as @yoshoku mentioned the size will be around 4 to 6 gb i think

[jaymehta-ce]

Already installed but still getting the same error. Are there any specific node version required?

[lucky-9]

Installed the tools, still facing the issue.

I do not have a Windows PC so I do not know, but the node-gyp documentation says you also need to install Python from the Microsoft Store package, and if that does not work, further reference documentation is shown:
https://github.com/Microsoft/nodejs-guidelines/blob/master/windows-environment.md#compiling-native-addon-modules

This is not an hnsw-node issue, but a node-gyp issue, so please ask in a node-gyp repository or on stack overflow.
