环境 win7 node9.9 npm6.3 node-gyp3.7.0
npm install node-gyp -g
1.github上下载最新ffi代码
https://github.com/node-ffi/node-ffi
2.用cpm安装ffi需要的模块
3.node-gyp configure
node-gyp build
4.编译好不出错后就可以拷到别处用了。下面代码可以测试编译好了么。调用windows里的user32.dll
var FFI = require('./node_modules/node-ffi'); function TEXT(text){ return new Buffer(text, 'ucs2').toString('binary'); } var user32 = new FFI.Library('user32', { 'MessageBoxW': [ 'int32', [ 'int32', 'string', 'string', 'int32' ] ] }); var OK_or_Cancel = user32.MessageBoxW( 0, TEXT('I am Node.JS!'), TEXT('Hello, World!'), 1 ); console.log(OK_or_Cancel);
如果linux下就可以下载node-ffi直接npm i 然后 node-gyp configure node-gyp build
