Can't get Gulp to run: cannot find module 'gulp-util'
提问by Nicolas Le Thierry d'Ennequin
On Windows 7, I've installed gulp as explained here: http://markgoodyear.com/2014/01/getting-started-with-gulp/:
在 Windows 7 上，我已经按照此处的说明安装了 gulp：http: //markgoodyear.com/2014/01/getting-started-with-gulp/：
npm install gulp -g- In my app folder:
npm install gulp --save-dev - I create a
gulpfile.jsfile.
npm install gulp -g- 在我的应用程序文件夹中：
npm install gulp --save-dev - 我创建一个
gulpfile.js文件。
But then, when I try to run gulp, I get this error message:

module.js:340
throw err;

Error: cannot file module 'gulp-util'
at Function.Module._resolveFilename (module.js:338:15)
etc.
等等。
But gulp-utilis present (in the local app folder) in:
但是gulp-util存在于（在本地应用程序文件夹中）：
node_modules
gulp
node_modules
gulp-util
Any idea what may be the cause?

Any answer didn't help in my case.
What eventually helped was removing bowerand gulp(I use both of them in my project):
在我的情况下，任何答案都没有帮助。最终有帮助的是删除bower和gulp（我在我的项目中同时使用了它们）：
npm remove -g bower
npm remove -g gulp
After that I installed them again:
之后我再次安装它们：
npm install -g bower
npm install -g gulp
Now it works just fine.
现在它工作得很好。

Linux Ubuntu 18:04user here. I tried all the solutions on this board to date. Even though I read above in the accepted answer that "From later versions, there is no need to manually install gulp-util.", it was the thing that worked for me.(...maybe bc I'm on Ubuntu? I don't know. )
Linux Ubuntu 18:04用户在这里。迄今为止，我尝试了该板上的所有解决方案。即使我在上面接受的答案中读到“从更高版本开始，无需手动安装 gulp-util”。，这对我有用。（...也许 bc 我在 Ubuntu 上？我不知道。）
To recap, I kept getting the "cannot find module 'gulp-util'" error when just checking to see if gulp was installed by running:
回顾一下，当我通过运行检查是否安装了 gulp 时，我不断收到“找不到模块‘gulp-util’”错误：
gulp --version
...again, the 'gulp-util' error kept appearing...
...再次，'gulp-util' 错误不断出现...
So, I followed the npm install [package name] advice listed above, but ended up getting several other packages that needed to be installed as well. And one had a issue of already existing, and i wasn't sure how to replace it. ...I will put all the packages/install commands that I had to use here, just as reference in case someone else experiences this problem:
所以，我遵循了上面列出的 npm install [package name] 建议，但最终得到了其他几个需要安装的软件包。并且有一个已经存在的问题，我不知道如何替换它。...我将把我必须使用的所有包/安装命令放在这里，作为参考，以防其他人遇到这个问题：
sudo npm install -g gulp-util
(then I got an error for 'pretty-hrtime' so I added that, and then the others as Error: Cannot find module ___ kept popping up after each gulp --version check. ...so I just kept installing each one.)
（然后我收到了'pretty-hrtime'的错误，所以我添加了它，然后其他错误：无法找到模块___在每次gulp --version检查后不断弹出。......所以我只是继续安装每个。 )
sudo npm install -g pretty-hrtime
sudo npm install -g chalk
sudo npm install -g semver --force
(without --force, on my system I got an error: "EEXIST: file already exists, symlink". --force is not recommended, but idk any other way. )
（没有--force，在我的系统上，我收到一个错误：“EEXIST：文件已经存在，符号链接”。不推荐使用--force，但可以通过其他方式识别。）
sudo npm install -g archy
sudo npm install -g liftoff
sudo npm install -g tildify
sudo npm install -g interpret
sudo npm install -g v8flags
sudo npm install -g minimist
And now gulp --version is finally showing: CLI version 3.9.1 Local version 3.9.1
现在 gulp --version 终于显示：CLI version 3.9.1 Local version 3.9.1

You should install these as devDependencies:
- gulp-util
- gulp-load-plugins
您应该安装这些为devDependencies：
- gulp-util
-gulp-load-plugins
Then, you can use them either this way:
然后，您可以通过以下方式使用它们：
var plugins = require('gulp-load-plugins')();
Use gulp-util as : plugins.util()
or this:
或这个：
var util = require('gulp-util')

Same issue here and whatever I tried after searching around, did not work. Until I saw a remark somewhere about global or local installs. Looking in:
同样的问题在这里以及我在四处搜索后尝试的任何内容都不起作用。直到我在某处看到有关全局或本地安装的评论。在看：
C:\Users\YourName\AppData\Roaming\npm\gulp

I indeed found an outdated version. So I reinstalled gulp with:

In most of the cases, deleting all the node packages and then installing them again, solve the problem.
在大多数情况下，删除所有节点包然后重新安装它们，可以解决问题。
But In my case node_modules folder has not write permission.
但就我而言， node_modules 文件夹没有写权限。

I had the same issue, although the module that it was downloading was different. The only resolution to the problem is run the below command again:
我有同样的问题，虽然它下载的模块不同。该问题的唯一解决方案是再次运行以下命令：
