Hi,

I can't install scrypt in windows 10 , I am getting following error.

On Windows 10, Scrypt is built using node-gyp, which can be acquired by globally installing Microsoft's Windows Build Tools, so install that first from an elevated PowerShell or CMD.exe (run as Administrator). npm install --global --production windows-build-tools It takes a while. Then get node-gyp: npm install -g node-gyp Then you should be able to run npm install scrypt This info comes from node-gyp's github page.

[sivahanuman]

I have tried the command before post here , doesn't work

[ml1nk]

My last try with npm install --global --production windows-build-tools wasn't successful, too. I installed the build tools directly, then it worked.

Alternative this issue seems to address the same problem https://github.com/nodejs/node-gyp/issues/671

Something is probably wrong with your configuration, as error messages like

MSB4019: The imported project "C:\Program Files (x86)\MSBuild\Microsoft.Cpp\v4.0\v110\Microsoft.Cpp.Default.props" was not found. Confirm that the path in the declaration is correct, and that the file exists on disk.

leads to the issue in my previous post or pages like: https://www.codesd.com/item/why-does-msbuild-look-in-c-for-microsoft-cpp-default-props-instead-of-c-program-files-x86-msbuild-error-msb4019.html

[sivahanuman]

Nope doesn't help

[sivahanuman]

finally successfully installed

workaround

1. reinstall vc++ build tools for vs2015

2. Manually add the string value in Computer\HKEY_LOCAL_MACHINE\SOFTWARE\WOW6432Node\Microsoft\MSBuild\ToolsVersions\14.0

key = VCTargetsPath
value = C:\Program Files (x86)\MSBuild\Microsoft.Cpp\v4.0\v140

@sivahanuman if you are using Node v10.5.0 (current), scrypt has finally been released as part of the crypto module: I have written a zero-dependency npm module scrypt-kdf which you might find interesting as it has none of the issues of native abstractions, and which I would be glad for you to try out.

It has a slightly simplified API compared with this module (it is promise-based and interfaces with strings rather than buffers), but it operates on the same stored password hashes.

If you try it, let me know your experiences! @chrisveness

[jaipraveen51]

@chrisveness

I tried to install scrypt-kdf but below error

My original intention was to npm install a github downloaded package related to ethereum/solidity

I encountered config.h missing input file error and I tried setting up windows-build-tools command and tried few other options, so far no luck.

Can you please advise? I have already posted a message at scrypt issue page yesterday.

[0xAshish]

@sivahanuman what's node -v

[chrisveness]

@jaipraveen51 I can't quite make sense of that screenshot, but it looks like errors coming from scrypt, rather than scrypt-kdf - try making sure scrypt is removed from package.json (with scrypt-kdf in its place), delete the node_modules directory, and run npm install again.

[sriharikapu]

This is crazy the node-gyp doesn't work at all. I tried all the ways. What all I tried:

1. Python issue - install new python 2.7 and set path - still node-gpy it didn't work
2. Install build tools from the VS - still node-gpy it didn't work
3. Build build tools from the github - still node-gpy it didn't work
4. Rebuild node-gyp - still node-gpy it didn't work
5. Remove node-gyp and reinstall - still node-gpy it didn't work
6. npm config set msvs_version 2013 --global - still node-gpy it didn't work
7. VC++ doesnt work as well

scrypt@6.0.3 install:node-gyp rebuild Scrypt cannot be installed.

RIP

[chrisveness]

@sriharikapu, this repo is no longer maintained.

If you are using scrypt.hash, it is now available natively in the Node.js crypto module.

If you are using scrypt.kdf / scrypt.verifyKdf, scrypt-kdf is a close-to-direct replacement.

[sriharikapu]

@chrisveness I will check and get back to you

[sriharikapu]

I was using scrypt.hash

[sriharikapu]

same story on my other windows :

[chrisveness]

@sriharikapu use crypto.scrypt() in Node 10.5.0+, or scrypt-async for Node < 10.5.0.

[sriharikapu]

I am currently using scrypt-async its not working with any node version for me on my windows.

[japinzonn]

Hi. I had the same problem. What I did was create the entire project by running the cmd command as administrator:

• mkdir my_project
• npm install -y
• npm init -y
• npm install web3 solc @ 0.4.25
• npm install ganache-cli

[matsushou]

Downgrading Node.js (npm) works for me.

[ghost]

Windows 10 64 bit Downgrade Node.js 12.13.0 to Node.js 10.17.0 works.

Windows 10 64 bit Downgrade Node.js 12.13.0 to Node.js 10.17.0 works.

Indeed this made my environment to pass the point of installing scrypt, which was somehow required for ethereum-alarm-clock
