npm error “Keccak bindings compilation fail.” while installing truffle

问题

I tried to install Truffle, but then I got this error:

$ npm install -g truffle
    C:\Users\dany.vandermeij\AppData\Roaming\npm\truffle -> C:\Users\dany.vandermeij\AppData\Roaming\npm\node_modules\truffle\build\cli.bundled.js

> npm run rebuild || echo "Keccak bindings compilation fail. Pure JS implementation will be used."


> keccak@1.4.0 rebuild C:\Users\dany.vandermeij\AppData\Roaming\npm\node_modules\truffle\node_modules\keccak

I tested the truffle commands and they seem to work, but I dont know why I get this error...

Thank you for your help

回答1:

Use npm install -g truffle --unsafe-perm to install truffle this is probably happening due to a syntax issue of keccak which shouldn't affect functionality.

UPDATE (Windows)

npm install --global windows-build-tools
