npm prune removes dependency module - npm

In my package.json file I have:
"dependencies": {
"#aws/dynamodb-data-mapper": "^0.7.3",
"#aws/dynamodb-data-mapper-annotations": "^0.7.3",
"#my-company/common": "file:../common",
...
}
#my-company/common specifies a local module which is installed by yarn.
However, when I run npm prune, this module is pruned.
I thought that including it in the package.json dependencies object would stop it from being pruned? Did I miss something?

For those who come across this, I discovered that running npm ls showed that there was an error with the common module.
Installing with NPM instead of Yarn fixed the issue.
Installing with Yarn did create the package within node_modules, however there was obviously an error somewhere which I couldn't uncover.

"resolved" and "integrity" go missing in package-lock.json

Ocassionally, when installing an (unrelated) dependency, I lose the resolved values from each of my private nexus repository dependencies, meaning that when my build server runs npm ci it falls back to attempting to install these from the npm repository, which obviously fails.
I am using npm 8.5.5/node 16.15
I am using NPM's workspaces feature to construct a monorepo, meaning that I have several project package.json files as well as a root package.json
My .npmrc (at root level) looks like this:
engine-strict=true
#foo:registry=http://prod-nexus.foo.com/repository/bar/
always-auth=true
After an (unrelated, random) install my package-lock.json will have this change:
"#foo": {
"version": "1.2.3",
- "resolved": "http://prod-nexus.foo.com/repository/bar/#foo/-/lib-1.2.3.tgz,
- "integrity": "sha...",
+ "license": "MIT",
"dependencies": { ....
Note that the resolved and integrity fields have disappeared and the license has been added.
I have run into this problem several times, each time I have solved it by rolling back and some manual editing and eventually it goes away, but I really need to understand what is going on.
What is causing this, why is it random, what can I do to defend against it?
This could be related to the issue https://github.com/npm/cli/issues/4263
clean the npm cache npm cache clean -f
run npm install again
If that doesn't work, try it again while deleting more:
clean the npm cache npm cache clean -f
remove node_modules in project folder
remove package-lock.json file
run npm install again

How can resolve the NPM issue? Stuck with npm start error

The issue I have is that npm start cannot start. I tried to fix with audit, deleted node_dependency directory and re-installed with npm, nothing works.
One concrete issue I see is:
The react-scripts package provided by Create React App requires a dependency:
"webpack": "4.44.2"
Yet, I also see npm -v webpack -> 6.14.14. How do I need to debug this?
Your npm -v webpack command is not correct. it will return npm version and not the webpack version.
Try npm ls webpack . you can also check your package.json file for the packages you have. or run npm ls for the full list.
make sure to install the required dependency as it states.
Eventually I could not solve the package problem with an informed debugging.
What I did was to (npm install --global yarn) and start the application through it (yarn start). It worked a lot to download the packages and eventually started the application.
So, I guess I need to switch to yarn after this point, which is ok, as long as it works :)

How to remove an invalid local dependency from package-lock.json and package.json?

Let's say that someone installed an invalid local dependency. (file does not exists locally)
package-lock.json
"mock-framework": {
"version": "file:../../../mock-framework",
package.json:
"dependencies": {
"mock-framework": "file:../../../mock-framework"
}
I need to reinstall the framework, but it's located differently on my machine and does not follow the structure that was provided in the package locks. Because running the npm install command is giving me the error:
Could not install from "../../../mock-framework" as it does not contain a package.json file.
Would it be possible to clean it up through the command line? I tried with npm uinstall and still no luck.
I recently faced similar issue with local dependency integrity in package-lock.json
Ideally npm uninstall should remove the entry in package-lock.json but since it is not and you only have one local framework as changed dependency, you can try following -
Fix the dependency path and run rm package-lock.json && npm i
Hope I'm inline to your problem statement.

webpack is not recognized as a internal or external command,operable program or batch file

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.

grunt js installing packages

I'm building a grunt javascript project with grunt, and I have a package.json file that looks something like:
{
... name, author, etc here ...
"dependencies": {
"grunt-html":"0.2.1"
}
}
I can run npm install to install grunt-html and this works just fine. But when I add new dependencies, all developers on the team must know to run npm install again. Is there a way to automatically install any packages that have not yet been installed? Should I just run npm install always to ensure I'm up to date?
Yes npm install is the easiest way IMO. Getting everyone familiar with the other npm commands makes managing deps easier as well. Such as:
npm ls to list out the currently installed modules.
Or the --save flag ie, npm install grunt-html --save to install and insert the package and version into your package.json.
npm prune to remove modules not included in your package.json.
Other ways to manage dependencies are to commit the node_modules folder in your repository to avoid other devs from having to run npm install. Or for more complex projects consider using npm shrinkwrap to lock down dependencies to specific versions: npm shrinkwrap docs.
I have not tried grunt-install-dependencies (https://github.com/ahutchings/grunt-install-dependencies), but it seems this may fullfill your needs. Just add the command install-dependencies as first task within your custom definfed grunt tasts, e.g.
grunt.registerTask('build', [ 'install-dependencies', 'useminPrepare', ... ]);
