启动快速服务器时出错

Question

当我尝试启动我的快递服务器时，我遇到了一个错误，我终其一生都找不到原因。它工作了一段时间，然后停止工作，但我不知道我会改变什么会破坏它。

这是输出：

0 info it worked if it ends with ok
1 verbose cli [ 'node', '/usr/local/bin/npm', 'start' ]
2 info using npm@2.7.4
3 info using node@v0.12.2

18 error This is most likely a problem with the mathlab package,
18 error not with npm itself.
18 error Tell the author that this fails on your system:
18 error     node ./bin/www
18 error You can get their info via:
18 error     npm owner ls mathlab
18 error There is likely additional logging output above.
19 verbose exit [ 1, true ]

希望这会有所帮助：

最新版本的 npm，可能是 2.0，如果 node 被 npm 以外的东西杀死，npm 脚本会抛出错误。我不确定当子进程被杀死时是否会发生这种情况。

尝试将此添加到您的脚本中：

process.on('SIGTERM', function(){
  console.log('Detected kill signal');
  process.exit()
})
