stdout is not a tty. Using bash for node + tape + tap-spec

问题

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

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

Its probably a problem with Windows 7 Git Bash Shell

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

To discard it run the following command :

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

For it to work you need the following output : true

Solution (for Windows):

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

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

回答2:

I had same problem on console "stdout is not a tty"

This because of console, while installing Git there is an option which is choosing default terminal. Install again Git and choose terminal as Windows console and after that it should be fine.
