node.js - 安装松露时出现 npm 错误 "Keccak bindings compilation fail."

Question

我尝试安装 Truffle，但随后出现此错误:

$ 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

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

我测试了松露命令，它们似乎有效，但我不知道为什么会出现此错误...

使用 npm install -g truffle --unsafe-perm安装松露这可能是由于 keccak 的语法问题而发生的，这不应该影响功能。

更新(Windows)

npm install --global windows-build-tools
