I reinstall node.js and python
here is my path
enter image description here
sorry for my bad english but i need help
As OP didn't provide details of the issue and seems to be new to nodejs, hereby explaining how npm i work in general matter.
There are main usage of npm i:
To install a package that haven't install in this project(or global) before, you can put that package name after the npm i , such as npm i express. Once the installation is done, it will insert the package name into package.json and the package source code in node_modules. You can think package.json is like a index and node_modules is the actual packages source code.
To install a package that listed in package.json. If you are copying/clone the project from other source , usually it has package.json but not the node_modules. In that case, you can use npm i to install all the packages that listed in package.json and it will then create the node_modules.
Using npm i without package.json will not install anything as there isn't a package name in the npm i [package name] and package.json .
I am trying to follow with pluralsight tutorial and he wrote npm install on the terminal, then a file called npm module is installed on the folder he specified. when I try to install npm this appears to me in the terminal, and the directory which Im trying to install npm on it contains only one document called package-lock.json enter image description here
npm install uses the package.json to install the necessary packages
I can see when you ls, there's no package.json in the directory, just the package-lock which is created where ever you run npm install
Make sure you run the npm install from the same directory the package.json in contained in
the problem is solved, I think that I download the web-dev-starter folder twice by mistake.
I have NPM installed in my PC how to use it for a new project?
or do I have to install npm for every new project?
NPM is extremely useful, but, when you install it, you install it globally. It comes with Node JS, so when you install Node JS, you should have npm installed(type npm -v to see the version and whether npm is installed).
"npm init" creates a package.json for your folder, which contains all the information about the version number, the name of the project, and some other information. In package.json, you can add dependencies, which basically say your project relies on that npm package.
"npm install" will install all the packages specified in package.json, and, if you want to install something specific, you would type "npm install ".
What happens when you do npm install in a dev environment on a project that has both a package.json and a npm-shrinkwrap.json file?
Will it ignore the shrinkwrap and use package.json for everything or just for the dev dependencies?
Any files added to the production dependencies in package.json will be ignored if they are not in the npm-shrinkwrap.json. Vis-à-vis: running npm install with foo-package added to the production dependency list will not install foo-package.
Not so for devDependancies.
Running npm install with foo-package added to the devDependency list will install foo-package even if it is not found in the npm-shrinkwrap.json file.
Fun.

Running just "npm install" will look for dependencies listed in your package.json. The error you're getting says that you don't have a package.json file set up (or you're in the wrong directory).
If you're trying to install a specific package, you should use 'npm install {package name}'. See here for more info about the command.
Otherwise, you'll need to create a package.json file for your dependencies or go to the right directory and then run 'npm install'.
I had this problem when trying to run 'npm install' in a Terminal window which had been opened before installing Node.js.
Opening a new Terminal window (i.e. bash session) worked. (Presumably this provided the correct environment variables for npm to run correctly.)
In my case it was due to a bad URL (http:// instead of git://, no .git at the end) for one of the dependencies.
You're likely not in the node directory. Try switching to the directory that you unpacked node to and try running the command there.
In case it helps anyone else - my issue was a rookie error, I had a space in the name line of my package.json and it caused the dependencies to be unreadable.
I came across this, and my issue was using an older version of node (3.X), when a newer version was required.
The error message actually suggested this as well:
...
Make sure you have the latest version of node.js and npm installed
...
So the solution may be as simple as upgrading node/npm. You can easily do this using nvm, the "Node Version Manager"
After you've installed nvm, you can install and use the latest version of node by simply running this command:
nvm install node
For example:
$ nvm install node

In mac you might have downloaded and installed Node js in
/Users/yourusername/Downloads/nodejs-todo-master , so go here and run npm install command, no need of sudo as well., you should get output like this...

First download json package file from https://github.com/npm/read-package-json
and then run npm install from terminal.
This is all because you are not in the desired directory. You need to first get into the desired directory. Mine was angular-phonecat directory. So I typed in cd angular-phonecat and then npm install.
If someone is in my situation facing this error and have tried all the above solutions, like:
you are in the right directory
you have a package.json file,
the JSON is valid,
you have tried to run %temp%
you have tried " npm install -d --save"
etc.
Mine worked by doing "npm install --force"
Note: This was also recommended in the error itself, which I didn't pay attention to earlier.
Even " Yarn install" worked.
npm install -d --save worked for me. -d flag command force npm to install your dependencies and --save will save the all updated dependencies in your package.json
For me I'm on windows 10 X64...
My code npm install on cmd failed
So instead of npm i used Yarn
Just type yarn install instead of npm install
This fixed my problem.Tried for 2 days finally found the best
solution
To install yarn , on cmd enter the following code
npm install --global yarn
To check if it has installed correctly enter the following code
yarn --version
Hey if you found error and it stuck while installing then try this
Open run and type %Temp% and delete all file
Then type prefetch on run app an delete all files then try it
These Will do the Job
npm install -g yarn
yarn install
or
npm install --force
Hey if you found error and stcuk while installing packages
,getting only three files like json file ,lock file and module file using yarn then try this using yarn.
Open run and type %Temp% and delete all file
Then type prefetch on run app an delete all files
Then type on CMD npx create -react-app it will give you all packages
