试图在Mac上运行Gulp，但不起作用

我正试着在我的Mac电脑上大口大口地运行。我进入终端，将cd刻录到我的吞咽文件夹中。我打字的时候

gulp

我得到-bash:gulp:command未找到。在我的gulp文件夹中，我确实有一个gulpfile.js，但我还是什么也没有得到。我该怎么办

以下是我在npm安装-g时遇到的错误：

---

你的机器上安装了Gulp了吗

如果您的文件夹中有package.json文件，请确保您可以在devdependency之间看到其中列出的Gulp。这些依赖关系是您在节点项目开发期间使用的

如果没有package.json文件，可以通过npm init在命令行中创建一个，然后使用npm install-g Gulp在计算机上本地安装Gulp，然后在项目文件夹中安装Gulp的命令行界面：npm install-save dev Gulp cli。CLI将使用项目中的Gulpfile.js运行Gulp可执行文件

更多信息可以在他们的网站上找到：

我有一个package.json文件。我从来没有安装过gulp，我不这么认为，但我只是运行了你的命令npm install-g gulp，我得到了一大堆错误。我将编辑我的问题以显示错误。因此，我尝试在父文件夹上为所有访问设置权限，但不起作用。是的，您似乎没有这样做的权限。这意味着您必须将sudo与npm命令一起使用，但这通常是不明智的。很多人都写过这样做的安全方法：--这很有效！不管怎么说，我还是做了sudo，看起来它成功了。后来输入gulp，它试图做些什么，但我还是收到了一个错误。我会为此开一张新票。谢谢
