I am currently building a cellphone application with react native. To create checkbox list, I was trying to install the component through npm.
npm install react-native-checkbox --save
However, I got two errors and I had no idea how to solve them. I have tried to clean the cache or reinstall the node but they didn't solve the problem. Could some give me some suggestions? Would appreciate any help.
It means there is no package.json in that location... Make sure you're in the right directory. You seem to be in your home directory.
To install and save a package you need to have a package.json, which there should already be one in your projects folder.
After navigating to the right folder, repeat your npm install and everything should be fine and dandy.

Im following along a tutorial on YT on how to code and deploy a react website. I created my project using Vite. Everything was reflecting fine on my browser window until I closed the terminal and now my browser returned "This page can't be reached". So I tried running npm run dev one more time and I get a bunch of errors. Looked online for an answer and ended up deleting both the package-lock.json and package.json folders. Now when I run npm install I only get a rather almost empty package-lock.json folder. Is there a way to undo this? I feel like I messed around too much with the terminal. How can I go back to running npm run dev effectively?
You need to install the packages again,
You need to initialize the package again.
I'd suggest going through the source code in order to find out the name of the packages.
npm init
then all you need to do is
npm i pkg1 pkg2 pkg3
I have just tried to view an old application of mine using npm start but it wont load keep getting the error.
Cannot find module 'C:\Users\Team Knowhow\development\Punk-API\node_modules\react-scripts\bin\react-scripts.js.
I tried creating a new react app and NPM start works fine so have no idea what the issue is with my old react app and why NPM start does not work.
Have you installed dependencies first using npm install.
If done already, try removing node_modules folder and installing dependencies again.
Make sure you have installed all dependencies including react-scripts!
You've to ensure that all the dependencies that your application is using is mentioned in the correct manner with their correct version in your pacakage.json file. And if that looks alright then run
npm i
or
npm install
This command will download all the dependencies that are mentioned in your package.json file.
I have an existing Vue project and I want to add Boostrap into it. I ran this command (following this tutorial)
npm install bootstrap jquery popper.js
And then, I got an error in the Vue project.
./node_modules/core-js/modules/es.array.iterator.js module build failed: error: enoent: no such file or directory
I have tried deleting node_modules folder and package-lock.json then running npm install, but it didn't work. I also have tried to clear cache but it didn't work. I also have tried running npm install from my cmd but it didn't work as well.
Any other suggestions? Thanks!
Which version of vue are you using (2, 3)? Have you considered using Bootstrap Vue?
I just did the same method a few hours later and it succeeded. I think probably it also depends on your Internet connection.
Node.js newbie here, Windows 10. I npm install-ed some packages (without -g) while inside a directory that didn't have package.json. npm placed the packages in C:\Users\{MyName}\node_modules\.
Now I'm seeing some weird behavior:
When I'm in my project directory (has package.json but no node_modules/ yet), npm list and npm list -g both show an empty list
When I'm in a non-project directory (no package.json)...
npm list -g still shows an empty list
However, npm list shows everything in C:\Users\{MyName}\node_modules\
Question 1. What is going on here? Apparently, npm's default global path should be C:\Users\{MyName}\AppData\Roaming\npm\. If so, why is it using C:\Users\{MyName}\node_modules\?
Question 2. How do I get out of this mess? Node.js has no problem importing packages from C:\Users\{MyName}\node_modules\, but I want npm to list them properly. How can I delete the semi-global packages, reinstall them correctly, and ensure that this doesn't happen again?
Welp, turns out I've been mistakenly npm install-ing packages without package.json. The first time I did this, I was in my home directory(C:\Users\{MyName}\). This caused npm to create node_modules/ and package-lock.json in the home directory. Further (mistaken) attempts to install packages in my projects--which were still missing package.json--caused npm to traverse upwards, until it found the initial node_modules/ dir, and install everything there. Because my home directory is among the places Node.js looks for modules, I didn't notice my mistake until now. :P
Not sure why it’s doing it, but the way to avoid it is to initialize your project directory using:
npm init
or if you don’t want to answer the questions:
npm init -y
That will setup the directory with the package.json and node_modules will be put there.
Ok, a couple of tips then...
when you install a package that you are going to use in production then add --save, e.g.
npm install --save some-package
this will automatically add the dependency to your package.json. If you are installing a package for use purely in development, e.g. chai, then use--save-devand it will add it to the development dependencies.
Also, git is your friend, even if you are only messing :)
Happy noding :)
For me the solution here was:
Go to c:\users[me]\AppData\Roaming\npm and delete the node_modules folder completely
Make sure I had the package.json file for the project
Delete the project package-lock.json file
Run npm init
Run npm install
Project then worked, not sure why the node_modules got to be in the folder above, ain't got time to find out.
I'm having a problem with npm.
When I install packages they will go to the node_modules folder, but instead of the package assets being in one folder it puts them outside of that folder.
In the express folder, all of the folders in that are supposed to be inside, but instead, they are outside of it. This also happens with other packages I try to install. I have tried creating a test project, but the same thing happened,
And I also tried uninstalling node and npm, and it is still happening.
You sure it's not dependencies?
NPM will install additional packages if you need them, and place them in root of the node_modules folder so that other modules later can use the same if they need them.
After running (edit: npm init first to get package.json in the root of the project) npm install express --save on empty project, I end up with
PS. Apologies if I misused terms, I'm still quiet new to node and npm
I found out what happened it was because of node v5.1.1 that the package folders were saving outside of the express folder once I went back to node v4.2.3 it made a node_modules folder inside the express folder.
Thanks again for everyones help
