I made windows update on this Sunday. From that point, I am not able to execute gulp commands. I am not sure if there is any relation between windows update and gulp command. I am getting below error.
I have installed gulp again by npm install gulp -g. I have restarted my machine and tried. But still same issue. I have added this in environment variables also.
I have followed all the instructions explained in this issue but no resolution found.
After installation of gulp globally when I run below command it is not list me gulp
You are checking the local packages, but you should check the global:
npm list -g --depth=0
I have a project about 4 months and suddenly the aurelia's CLI commands are not working.
When I try to execute au run --watch I receive a message with options to create a new project under the path.
I have already tried to uninstall and reinstall the aurelia CLI, It's not work.
The last thing I have done was to execute a git clean -xdf
I think that could be something on my project. Someone could help me?
ANSWER
After some attempts I fixed the problem:
1) I reinstall Git and Node;
2) I have deleted all the files under the \AppData\Roaming\npm-cache path;
3) I have checked if the Git and Node were in the PATH of environment variables;
4) I run the npm install command;
Is aurelia-cli included in the devDependencies of the project and also installed globally?
First, install globally:
npm i -g aurelia-cli
Then, in the project directory, install & save to devDependencies:
npm i --save-dev aurelia-cli
You should then be able to run au in the project directory and see that the build and run commands are now available.
Note that you'll also need to install the necessary gulp dependencies required by the tasks in your project devDependencies.
EDIT: See aurelia/cli/issues/485 which confirms that installing aurelia-cli as a local dependency fixes this issue.
For example, to launch locally installed gulp, I have to run the following command from inside of my project:
node_modules/gulp/bin/gulp.js
To be able to launch npm packages only by their name, I want to include node_modules relatively to project's root dir. Is this possible?
P.S
I know how to install npm packages globally, but I'm trying to avoid doing that.
I hope I understand you correctly: You are trying to execute programs like gulp from your local install.
You can set up a npm script like so in your package.json:
package.json
...
"scripts": {
"build": "./node_modules/.bin/gulp"
}
...
Then, you can run gulp via npm run build from your command line. (Or optionally you can type ./node_modules/.bin/gulp)
I am Learning React.js and i am using windows 8 OS.i have navigate to my root folder
1.Created the package.json file by npm init
2. install webpack by npm install -S webpack.now webpack has been downloaded to my modules folder
3. install webpack globally by typing npm install webpack -g
4. i am also having a webpack.config.js in my root folder which contains the source and ouput directory
5. when i type the webpack command i am getting the below error.
webpack is not recognized as a internal or external command,operable program or batch file
Better solution to this problem is to install Webpack globally.
This always works and it worked for me. Try below command.
npm install -g webpack
As an alternative, if you have Webpack installed locally, you can explicitly specify where Command Prompt should look to find it, like so:
node_modules\.bin\webpack
(This does assume that you're inside the directory with your package.json and that you've already run npm install webpack.)
I had this issue for a long time too. (webpack installed globally etc. but still not recognized)
It turned out that I haven't specified enviroment variable for npm (where is file webpack.cmd sitting)
So I add to my Path variable
%USERPROFILE%\AppData\Roaming\npm\
If you are using Powershell, you can type the following command to effectively add to your path :
[Environment]::SetEnvironmentVariable("Path", "$env:Path;%USERPROFILE%\AppData\Roaming\npm\", "User")
IMPORTANT : Don't forget to close and re-open your powershell window in order to apply this.
npm install -g webpack-dev-server will solve your issue
Try deleting node_modules in local directory and re-run npm install.
Maybe a clean install will fix the problem. This "command" removes all previous modules and re-installs them, perhaps while the webpack module is incompletely downloaded and installed.
npm clean-install
Add webpack command as an npm script in your package.json.
{
"name": "react-app",
"version": "1.0.0",
"scripts": {
"compile": "webpack --config webpack.config.js"
}
}
Then run
npm run compile
When the webpack is installed it creates a binary in ./node_modules/.bin folder. npm scripts also looks for executable created in this folder
Webpack CLI is now in a separate package and must be installed globally in order to use the 'webpack' command:
npm install -g webpack-cli
EDIT: Much has changed. Webpack folks do not recommend installing the CLI globally (or separately for that matter). This issue should be fixed now but the proper install command is:
npm install --save-dev webpack
This answer was originally intended as a "work-around" for the OPs problem.
We also experienced this problem and I like all the answers that suggest using a script defined in package.json.
For our solutions we often use the following sequence:
npm install --save-dev webpack-cli (if you're using webpack v4 or later, otherwise use npm install --save-dev webpack, see webpack installation, retrieved 19 Jan 2019)
npx webpack
Step 1 is a one-off. Step 2 also checks ./node_modules/.bin. You can add the second step as a npm script to package.json as well, for example:
{
...
"scripts": {
...
"build": "npx webpack --mode development",
...
},
...
}
and then use npm run build to execute this script.
Tested this solution with npm version 6.5.0, webpack version 4.28.4 and webpack-cli version 3.2.1 on Windows 10, executing all commands inside of a PowerShell window. My nodejs version is/was 10.14.2. I also tested this on Ubuntu Linux version 18.04.
I'd advise against installing webpack globally, in particular if you are working with a lot of different projects each of which may require a different version of webpack. Installing webpack globally locks you down to a particular version across all projects on the same machine.
npx webpack
It is worked for me. I'm using Windows 10 and I installed webpack locally.
For me it worked to install webpack separately. So simply:
$npm install
$npm install webpack
I'm not sure why this should be necessary, but it worked.
Just run your command line (cmd) as an administrator.
I've had same issue and just added the code block into my package.json file;
"scripts": {
"build": "webpack -d --progress --colors"
}
and then run command on terminal;
npm run build
you have to install webpack and webpack-cli in the same scope.
npm i -g webpack webpack-cli
or,
npm i webpack webpack-cli
if you install it locally you need to call it specifially
node_modules/.bin/webpack -v
Install WebPack globally
npm install --global webpack
I had this issue when upgrading to React 16.12.0.
I had two errors one regarding webpack and the other regarding the store when rendering the DOM.
Webpack Error:
webpack is not recognized as a internal or external command,operable program or batch file
Webpack Solution:
Close related VS Solution
Delete node_modules folder
Deleted package-lock.json
npm install
npm rebuild
Repeated this 2-3 times
Store Error:
Type Store<()> is not assignable to type Store<any, AnyAction>
Store Solution:
Suggestions to update my React version didn't fix this error for me, but irrespective I would recommend doing it.
My code ended up looking like this:
ReactDOM.render(
<Provider store={store as any}>
<ConnectedApp />
</Provider>,
document.getElementById('app')
);
As per this solution
This below-given commands worked for me.
npm cache clean --force
npm install -g webpack
Note - Run these commands as administrator. Once installed then close your command prompt and restart it to see the applied changes.
If you create a boilerplate folder for your JS projects so that you can use JS Modules, webpack and Babel are great tools.
Don't install webpack globally and after installing the most recent versions of both, your package.json file will be loaded up and ready to copy for future projects.
Make sure to delete the node_modules folder to decrease file size in your boilerplate folder and then to reinstall node_modules use npm install.
I forgot to run npm install and kept getting this error when trying to run my webpack dev-server until I realized I needed to run npm install to install node_modules and then it worked.
If you have just cloned a repo, you first need to run
npm install
The error your getting will be generated if you are missing project dependencies. The above command will download and install them.
I got the same error, none of the solutions worked for me, I reinstalled node and that repaired my environment, everything works again.
I also Face the same issue this command works for me
npm install --save-dev webpack
Try this folks, the cli needs to be updated to the latest version
npm install --save-dev #angular/cli#latest

The fix for me was locally installing webpack as devDependency. Although I have it as devDependencies it was not installed in node_modules folder. So I ran
npm install --only=dev
Sometimes npm install -g webpack does not save properly. Better to use npm install webpack --save . It worked for me.
I had this same problem and I couldn't figure it out. I went through every line of code and couldn't find my error. Then I realized that I installed webpack in the wrong folder. My error was not paying attention to the folder I was installing webpack to.
Hi I'm trying to install Grunt on Windows 7 64 bit. I have installed Grunt using commands
npm install -g grunt
npm install -g grunt-cli
but now if I try to do grunt init, it is throwing me an error -
A valid Gruntfile could not be found. Please see the getting started
guide for more information on how to configure grunt:
http://gruntjs.com/getting-started Fatal error: Unable to find
Gruntfile.
But when I look inside the grunt folder on my system the Gruntfile.js is there. can someone please guide me how to install this grunt properly and how to write built Script using the grunt. I have one HTML page and java script if i wants built a script using Grunt how can i do it?
To setup GruntJS build here is the steps:
Make sure you have setup your package.json or setup new one:
npm init
Install Grunt CLI as global:
npm install -g grunt-cli
Install Grunt in your local project:
npm install grunt --save-dev
Install any Grunt Module you may need in your build process. Just for sake of this sample I will add Concat module for combining files together:
npm install grunt-contrib-concat --save-dev
Now you need to setup your Gruntfile.js which will describe your build process. For this sample I just combine two JS files file1.js and file2.js in the js folder and generate app.js:
module.exports = function(grunt) {
// Project configuration.
grunt.initConfig({
concat: {
"options": { "separator": ";" },
"build": {
"src": ["js/file1.js", "js/file2.js"],
"dest": "js/app.js"
}
}
});
// Load required modules
grunt.loadNpmTasks('grunt-contrib-concat');
// Task definitions
grunt.registerTask('default', ['concat']);
};
Now you'll be ready to run your build process by following command:
grunt
I hope this give you an idea how to work with GruntJS build.
NOTE:
You can use grunt-init for creating Gruntfile.js if you want wizard-based creation instead of raw coding for step 5.
To do so, please follow these steps:
npm install -g grunt-init
git clone https://github.com/gruntjs/grunt-init-gruntfile.git ~/.grunt-init/gruntfile
grunt-init gruntfile
For Windows users: If you are using cmd.exe you need to change ~/.grunt-init/gruntfile to %USERPROFILE%\.grunt-init\. PowerShell will recognize the ~ correctly.
Some time we need to set PATH variable for WINDOWS
%USERPROFILE%\AppData\Roaming\npm
After that test with where grunt
Note: Do not forget to close the command prompt window and reopen it.
I got the same issue, but i solved it with changing my Grunt.js to Gruntfile.js
Check your file name before typing grunt.cmd on windows cmd (if you're using windows).
You should be installing grunt-cli to the devDependencies of the project and then running it via a script in your package.json. This way other developers that work on the project will all be using the same version of grunt and don't also have to install globally as part of the setup.
Install grunt-cli with npm i -D grunt-cli instead of installing it globally with -g.
//package.json
...
"scripts": {
"build": "grunt"
}
Then use npm run build to fire off grunt.
