NPM cannot install "truffle" on Windows

Question

I am trying to install "truffle" with npm, but I am not familiar with NodeJS and cant figure out why npm wont install it. I try npm install -g truffle in Powershell with Admin rights and after a few lines of output I get this block of error messages:

 gyp ERR! build error
 gyp ERR! stack Error: `C:\Program Files (x86)\MSBuild\14.0\bin\msbuild.exe` failed with exit code: 1
 gyp ERR! stack     at ChildProcess.onExit (F:\nodeJS\node_modules\npm\node_modules\node-gyp\lib\build.js:276:23)

 gyp ERR! node -v v4.5.0
 gyp ERR! node-gyp -v v3.4.0
 gyp ERR! not ok\

And then after many many yellow lines I finally get this:

 npm ERR! Windows_NT 10.0.14393
 npm ERR! argv "F:\\nodeJS\\node.exe" "F:\\nodeJS\\node_modules\\npm\\bin\\npm-cli.js" "install" "-g" "truffle"

 npm ERR!     npm owner ls scrypt
 npm ERR! There is likely additional logging output above.

 npm ERR! Please include the following file with any support request:

After that nothing else happens and after a while it just terminates. There are no files (other than a single log file) in the directory I am currently in and the keyword "truffle" can also not be found by cmd/powershell.

As I said I have never worked with NodeJS before and have no idea what all this means. What I can do to get truffle running?

Answer 1

Your install is failing at node-gyp rebuild. Solutions to this problem are listed on the node-gyp repo. The quickest is:

"Option 1: Install all the required tools and configurations using Microsoft's windows-build-tools using npm install --global --production windows-build-tools from an elevated PowerShell or CMD.exe (run as Administrator)." This will install Python and Visual Studio correctly.

Also, you are using Node 4.5. The recommended version is 5+, according to the Truffle Docs

Ululant

if the installation is failing not finding Visual Studio, then install the Latest Version of Visual studio (say community edition 2022), having the 'Desktop development with c++' is selected while installing. Ensure you have all this.

I was also facing the same problem...

Solution:

Run as administrator

npm install --global windows-build-tools

npm install -g truffle
