节点脚本抛出 uv_signal_start EINVAL [英] Node script throws uv_signal_start EINVAL

问题描述

我正在运行 Ubuntu 12.10 并开始使用 Node.

I'm running Ubuntu 12.10 and getting started with Node.

我首先使用 Ubuntu 存储库安装了节点.我遇到了一些麻烦，所以我使用 Chris Lea 的存储库重新安装.在那之后，节点运行得更好，没有之前的错误.

I first installed node using the Ubuntu repositories. I ran into some trouble with something, so I re-installed using Chris Lea's repository. After that, node was running better, without that previous error.

然后我运行 sudo npm install node-dev -g

但是运行 node-dev script.js 不起作用.

But running node-dev script.js wasn't working.

Error:
node.js:762
          throw errnoException(process._errno, 'uv_signal_start');
                ^
Error: uv_signal_start EINVAL

推荐答案

错误不在于 node-dev，而在于您的脚本.Error: uv_signal_start EINVAL 在您尝试使用 SIGKILL 或 SIGSTOP 时在较新版本的节点中抛出，如下所示:

The error isn't with node-dev, but rather in your script. Error: uv_signal_start EINVAL is thrown in newer versions of node when you're trying to work with SIGKILL or SIGSTOP, like so:

process.on('SIGKILL', function() { // etc, etc

您可能在早期版本中避开了这个问题，但新版本现在会抛出此错误(有关详细信息，请参阅 此 GitHub 问题).

You probably got away with this in earlier versions, but newer versions will now throw this error (see this GitHub issue for details).
