stdout不是tty.将bash用于节点+磁带+点击规范 [英] stdout is not a tty. Using bash for node + tape + tap-spec

问题描述

正在观看录像带+点击视频，并尝试使其正常工作.
作业系统:Windows 7 Git Bash Shell

Was looking at a tape + tap video and tried to get it to work.
OS: Windows 7 Git Bash Shell

node main.js | ./node_modules/.bin/tap-spec

stdout不是tty.

stdout is not a tty.

main.js:

var test = require('tape');
var add = require('./add');

test('add: two numbers add correctly', function(t) {
var actual = add(1,2);
var expected = 3;
t.equal(actual, expected);
t.end();
});

add.js:

module.exports = function(a, b) {
return a + b;
};

winpty节点main.js | ./node_modules/.bin/tap-spec 不能解决问题.

winpty node main.js | ./node_modules/.bin/tap-spec doesn't fix the problem.

推荐答案

诊断:

代码没有错，我得到以下输出:(OS:ArchLinux)

Diagnose :

Theres nothing wrong with the code, I get the following output : (OS : ArchLinux)

  add: two numbers add correctly

    ✔ should be equal


  total:     1
  passing:   1
  duration:  14ms

可能是Windows 7 Git Bash Shell

我在某处读到:通过管道发送输出已被Git Bash破坏

I read somewhere : sending output through a pipe is broken with Git Bash

要丢弃它，请运行以下命令:

To discard it run the following command :

node -p -e "Boolean(process.stdout.isTTY)"

要使其正常工作，您需要以下输出:true

For it to work you need the following output : true

$ node -p -e "Boolean(process.stdout.isTTY)"
false

使用 winpty工具，它会创建一个隐藏的控制台并封送它与Cygwin之间的I/O. /GitBashshell模拟pty:

Using the winpty tool, it creates a hidden console and marshals I/O between it and Cygwin/GitBashshell emulated pty :

$ winpty node -p -e "Boolean(process.stdout.isTTY)"
true
