error installing argon2 using npm install in node js (node-gyp) error

Question

I tried to install argon 2 on node js using npm install argon2 --save . I think there is a problem with python (not sure why) or with node-gyp.

PS C:\angular\backend> npm install argon2 --save

> argon2@0.21.0 install C:\angular\backend\node_modules\argon2
> node-gyp rebuild

expected argon2 to be installed to later be used for hashing.

Answer 1

From your anaconda path it looks like you were using Python 3.

gyp ERR! stack Error: Command failed: C:\Users\matan\Anaconda3\python.EXE -c import sys; print "%s.%s.%s" % sys.version_info[:3];
gyp ERR! stack   File "<string>", line 1
gyp ERR! stack     import sys; print "%s.%s.%s" % sys.version_info[:3];
gyp ERR! stack                                ^
gyp ERR! stack SyntaxError: invalid syntax

That would explain the syntax error at the print statement since it is not a print function. Try installing python2, or if you already have it installed, make sure it is on the path before python3.

Answer 2

its so simple to handle this error if you follow my step you can resolve all error in gyp in nodejs in windows os .

STEP1 : goto this link

find and download and install build tools for visual studio 2019 download and install it , and check nodejs tick , and restart your pc.

STEP2: install python 2.7 and sure that itis in your path , and u can access that with python (not python2)

STEP 3 : install this package fom npm https://www.npmjs.com/package/windows-build-tools make sure using powershell

then can install argon2 or any package you want :)
