Error in installing 'nodemon' using 'npm'

I recently started working with 'npm' and while installing 'nodemon' using command -
npm i -g nodemon
but it is showing ERR!
npm ERR! code EACCES

I tried using sudo to install nodemon, clearing cache using npm cache clear even with --force but no help, also tried what terminal was showing me could be the erroe but turned out nothing helpful.

Be careful with this stuff!!
Don't arbitrarily run sudo commands. Some answers online will tell you to run chmod or chown in your /usr directory. This is not a good solution and may potentially break your whole system!
The problem is that npm is trying to install global packages in your /usr folder, but your user doesn't have access to this folder. What you need to do is tell npm to install global packages in a folder which you do have access to.
Create a directory for global npm packages:
mkdir "${HOME}/.npm-packages"
Tell npm where to store globally installed packagesL
npm config set prefix "${HOME}/.npm-packages"
Ensure npm will find the location by adding it to your system's PATH variable. This can be done by editing .bashrc or .zshrc in your home directory and adding the following code to the bottom of the file.
NPM_PACKAGES="${HOME}/.npm-packages"
export PATH="$PATH:$NPM_PACKAGES/bin"
# Preserve MANPATH if you already defined it somewhere in your config.
# Otherwise, fall back to `manpath` so we can inherit from `/etc/manpath`.
export MANPATH="${MANPATH-$(manpath)}:$NPM_PACKAGES/share/man"
Close and re-open your terminal.

Cross reference npm install package inside workspace

I have workspace with several packages and plan to reference one to other.
+ root
|-+ packages
|-+ openapi-jsdoc
|-+ api-1
|-+ api-2
My api-1 and api-2 would like to use openapi-jsdoc, which in my imagination is as easy as doing cd packages/api-1; npm install ../openapi-jsdoc. But it is not, and found weird errors.
$ npm install ../packages/openapi-jsdoc
npm ERR! Cannot set properties of null (setting 'dev')
$ npm install packages/openapi-jsdoc
npm ERR! code 128
npm ERR! An unknown git error occurred
npm ERR! command git --no-replace-objects ls-remote ssh://git#github.com/packages/openapi-jsdoc.git
npm ERR! ERROR: Repository not found.
npm ERR! fatal: Could not read from remote repository.
$ npm install git+file:packages/openapi-jsdoc/
npm ERR! code 128
npm ERR! An unknown git error occurred
npm ERR! command git --no-replace-objects ls-remote file://packages/openapi-jsdoc/
Is there any concept of workspace I'm missed out. Then, how to do this correctly?

You probably need to use unsafe-perm
either:
add a file called .npmrc in your project's root directory and put this in it
unsafe-perm=true
OR
just use this command before installing (I didn't confirm this)
sudo npm config set unsafe-perm true
Basically npm would download the packages as root but then try to install the binaries as a local user without root permissions so it wouldn't have access to the directory where the binaries were downloaded at.
You just better double check the packages that you install to make sure they are trustworthy, otherwise it's safe to do so
Note: I only tried it on node 14, didn't test it on node 16

cannot install npm? problems generating application

ok ... first time I'm trying my hand at node.js.
installed it a while back, and not sure how i installed it.
last night, decided to tackle a tutorial regarding node.js and express.
checked my version of node which is v0.8.14 and npm which is 1.1.65. (I'm on Mac, 10.6.8 version)
but did this anyway
npm install -g express
seemed to go ok ... but whenever I tried to generate a new application via
express new ProjectName
I got this:
-bash: express: command not found
Decided to try
sudo npm install express -g
which again seemed to go well ... but again, the express new ProjectName got the same statement.
tried again:
npm install -g express
got a lot of errors unlike the first time.
npm WARN package.json application-name#0.0.1 No README.md file found!

and so it went on and on: errors ... or no errors. I'm at total loss. and online literature on fixing this problem seems rather sparse.
advice, please?
oh, also saw this somewhere online: (whatever it means)
/usr/local/share/npm/bin/express
which resulted in this:
destination is not empty, continue?
destination is not empty, continue? (yes or no) yes

so ... ??? any advice would be appreciated! (please also let me know if I left any pertinent information required)

Sounds like you need to edit your path variable.
Edit your ~/.bash_profile. Add this export somewhere.
export PATH=/usr/local/bin:$PATH:/usr/local/share/npm/bin
What's happening is that node isn't setting up its PATH correctly. I've had this happen to me before. Its something they should fix.
You may not have a .bash_profile. In *nix systems, there are a few different files you can place in your home directory to add environment variables and such.
bash_profile is the one I prefer, so in the terminal cd to ~ and touch .bash_profile.
Then edit it via nano .bash_profile or whatever editor you like.
(In nano, control-o to save, control-x to exit.)
When you've added it, do: source .bash_profile
Then try which express and see if it shows the path.

Installing Inotify with NPM

I'm quite new to nodeJS and I'm trying to install a package called inotify using the Node Package Manager (NPM).
After installing NPM (on OSX Lion), I tried to install inotify with the command:
sudo npm install inotify
And I get the following error:

Can someone help me out with this

The inotify module won't build because it can't find inotify_init. This is because inotify is not available on OS X.
The FSEvents API on OS X provides similar functionality, but it's a completely different API. The inotify module is not going to work in this situation.
Depending on what you are trying to do, fs.watch might suit your needs. It abstracts away platform differences:
On Linux systems, this uses inotify.
On BSD systems (including OS X), this uses kqueue.
On SunOS systems (including Solaris and SmartOS), this uses event ports.
On Windows systems, this feature depends on ReadDirectoryChangesW.
