NodeJS无法转到文件夹up以从child_process.spawn执行命令

Question

要启动WebPack (在父文件夹中)，我使用Gulp，但只要我尝试转到path中的父文件夹，就会得到一个错误。

大口吞下

var spawn = require('child_process').spawn;

gulp.task('_Scada2', function (done) {
  spawn('webpack', [], { cwd: '../../Scada.Web/' })
    .on('close', done);
});

获取错误

[14:20:47] '_Scada2' errored after 4.47 ms
[14:20:47] Error: spawn webpack ENOENT
    at Process.ChildProcess._handle.onexit (internal/child_process.js:229:19)

    at process._tickCallback (internal/process/next_tick.js:63:19)

Answer 1

试试__dirname + '../../Scada.Web/'
