Macos -在Mac中找不到bash:gulp:command

我尝试在mac中安装gulp，如下所示：

Is-iMac:~ itop$ npm root
/Users/itop/node_modules
Is-iMac:~ itop$ npm config set prefix /usr/local
Is-iMac:~ itop$ npm root -g
/usr/local/lib/node_modules
Is-iMac:~ itop$ sudo npm install -g gulp

安装后，我在终端中看到此错误：

npm WARN deprecated lodash@1.0.2: lodash@<3.0.0 is no longer maintained. Upgrade to lodash@^4.0.0.

编辑： 我试图通过以下方式发表这一评论：

并查看此错误：

如何修复此问题？

我认为您的系统中安装了gulp，或者至少您有一些与gulp相关的文件。只需执行

npm卸载--global-gulp-gulp-cli

，然后尝试使用

npm-install--global-gulp-cli

再次安装即可。如果这不起作用，我不知道您的系统上发生了什么。

转到

cd /usr/local/bin
ls -las

如果存在gulp，则删除该目录。（sudo rm-右前海湾）重新安装 一饮而尽

===================================================================

如果卸载节点不工作，请完全npm并重试

我自己刚刚遇到了这个问题，并设法通过以下方式解决了它：

$ npm uninstall --global gulp gulp-cli
$ rm /usr/local/share/man/man1/gulp.1
$ npm install --global gulp-cli

---

对我来说，只有当我使用

npm

而不是

warn

安装

gulp

时，它才起作用。非常奇怪。

在尝试了所有这些之后，我终于能够安装愚蠢的gulp

npm uninstall --global gulp gulp-cli

yarn global add gulp

@ArchiveVoyageur:谢谢，我尝试了这个，请查看我的编辑。我不确定我是否理解关于

文件存在的不清楚之处，请将其移走，然后重试。

…我想到的唯一一件事是，您可以从系统中安装unistall节点，然后重新安装它。但我对此没有多大希望，因为我不知道你的问题出在哪里。2017年11月为我工作——OSX Sierra。

npm uninstall --global gulp gulp-cli

yarn global add gulp
