我下载了 ros-control-center (https://github.com/pantor/ros-control-center)，我正在尝试为自己开发它。我已经安装了 npm，但是当我运行 gulp 时出现以下错误：

[09:12:35] Using gulpfile ~/proj/ros-control-centers/gulpfile.js

[09:12:35] Starting 'watch'...

这似乎是一个非常基本的问题，但我在网上找不到任何解决方案来解决这个问题。如果有人需要更多信息，请告诉我，并提前致谢！

【问题讨论】：

我克隆了上面的 repo 并安装了所有需要的包并执行了gulp。我在24 warnings 和0 errors 周围转悠。检查您是否安装了所有必需的软件包。

标签： javascript node.js gulp jslint ros

【解决方案1】：

感谢您的回答！如果我运行 npm install，据我所知，所有必需的软件包都已安装......我用 npm ls 检查了这些软件包我收到 3 个警告：

npm WARN deprecated minimatch@2.0.10: Please update to minimatch 3.0.2 or higher to avoid a RegExp DoS issue

npm WARN deprecated minimatch@0.2.14: Please update to minimatch 3.0.2 or higher to avoid a RegExp DoS issue

npm WARN deprecated graceful-fs@1.2.3: graceful-fs v3.0.0 and before will fail on node releases >= v7.0. Please update to graceful-fs@^4.0.0 as soon as possible. Use 'npm ls graceful-fs' to find it in the tree.

gulp 是全局安装的，我只做了 npm install。有什么明显的我忘记了吗？我是开发新手。
