purescript入门

Mim*_*imo 2 functional-programming ffi purescript

我刚刚开始通过示例学习purescript ,但是我在第2章的末尾使用了grunt项目模板.我按照说明操作,但是当我运行grunt命令时,我收到此错误:

/Users/chad/playground/purescript/tests/tmp/node_modules/Control.Monad.Eff.Random/index.js:8
return Math.random();
            ^

我通过深入研究代码发现,模块Math被导入为/output/Control.Monad.Eff.Random/index.jsas

var Math = require("Math");

function random() {
    return Math.random();
}
;

如果我删除导入,让Math是原生的并且index.js简单地运行main node index.js,一切正常.我想知道是否有什么我可以做的来解决这个问题,或者如果我做错了.

使用时,purescript-random模块在最新版本中被破坏psc-make.它将在下一版本0.6.7中由编译器补丁修复,希望本周.

作为解决方法,您应该能够purescript-randombower.json文件中或在命令行上指定以前的版本:

bower install purescript-random#0.1.1
