bower install command issuing EHTTP error - npm

I am struggling with installing bower on my system - although there are a few bower install issue scenarios on here, none are a very good match.
In my scenario, I have an externally acquired folder full of source code for a complex software package - the .bowerrc file is located here, as well as a bower.json. As is the default, my .npmrc file is located C:\Users\USER.
I have appended code strict-ssl=false and registry=http://registry.npmjs.org/ into .npmjs, and left the npm cache and config specs in the user directory. I've also left my PATH user variable as C:\Users\USER\AppData\Roaming\npm.
I have so far run three commands successfully:
npm install -g ember-cli
npm install -g bower
npm install
The created files from these commands seem to get dumped into C:\Users\USER\AppData\Roaming\npm\node_modules, and then the final command below is only giving me an EHTTP error.
bower install
I can only think that this issue is only occurring because of the location of the various dependencies. I've been playing around a bit - the last thing I tried was changing the Path user variable so that it instead points to the folder directory with .bowerrc, but the npm installation then has trouble referencing .npmrc. I'd appreciate any ideas, because I might only be chasing my own tail here.
UPDATE
I think I was wasting my time messing about with directory locations. The problem seems to be that there is a legacy proxy inside the .bowerrc file.. now I just need to work out how to get rid of the proxy setting!

NPM global install still creating a node_modules directory

In Ubuntu, I have a directory with my code /code which has my packages.json and such. My NPM prefix is /usr via npm prefix -g. I am trying to install packages globally so as to not create a node_modules directory in /code, but really as long as node_modules is not in /code, that will also work.
While in /code, I run npm install -g. I see a .staging directory created under my global prefix (eg, /usr/lib/node_modules/.staging) but then NPM takes another step and begins creating a /code/node_modules directory.
If I instead just run npm install -g <package> it correctly ends up in /usr/lib/node_modules/<package>. But I do not want to have to run npm install -g <package> for every package I need.
Why is NPM doing that and how can I make it stop doing that? At the very least, I would like the node_modules directory to NOT be in my /code directory (this is due to some environment constraints I can't change).
Globally installed packages are (almost always) not going to be used by your code. That's not how node or npm (conventionally) works. There isn't a shared global node_modules that programs all look in. (OK, there kinda is, but you don't want to use it if you can avoid it. Read on.) Having a local node_modules helps you avoid dependency hell. Global modules are for CLI tools that end up in your PATH and things like that.
You don't explain why you don't want a local node_modules for your project, so I will mention that if it is simply because it somehow bothers you, then please please please just get over it. You will be vastly happier. Type npm install and move on.
That said, for legacy reasons, your code in /code will look in /node_modules if there is no /code/node_modules. This is true for CommonJS modules that use require(). If you are using ESM modules via import, you may need to read the docs.
So, if you are using CommonJS/require(), you could have a directory structure like /project-name/code. You could have your index.js or whatever other code in the code subdirectory, while your package.json could be in project-name. Run npm install from /project-name and it will create a node_modules directory there rather than in the code subdirectory, and your Node.js files in code will find those modules.
If you don't like that, then for other options, you can review the relevant docs. At the time of this writing, those options include a NODE_PATH environment variable, $HOME/.node_modules, $HOME/.node_libraries, and $PREFIX/lib/node. However it all comes with this caveat that I implore you to abide by if you can:
It is strongly encouraged to place dependencies in the local node_modules folder. These will be loaded faster, and more reliably.

Why can't I run my node packages from the terminal?

Good evening,
I tried installing sails, yo, gulp & bower via the usual methods of npm i -g yo gulp bower etc but each time I open the terminal to run the command I always get the -bash: sails: command not found error.
I listed all my folders at the root of my folder and found the following:
The contents of the .npm-global/bin/ is actually all the packages I'm trying to use at the command line.
I decided to manual add the bin folder to the .bash_profile so it's contents was the following:
# Setting PATH for Python 3.7
# The original version is saved in su
export PATH="/Library/Frameworks/Python.framework/Versions/3.7/bin:${PATH}"
export PATH="/.npm-global/bin:${PATH}"
but that didn't work either.
Here's where I think the problem first arose - I think that the python install overrode all the previous paths in the file (or moved them somewhere perhaps?) so that all previous terminal commands now don't work.
The usual global install for node packages (/usr/local/lib/node_modules/npm/bin) contains the following:
What am I misunderstanding here & how can I fix this?

Where does npm store module when loading directly from github?

I have found a react-native module I would like to use. It contains an error which prohibits the installation.
I have forked the repository and corrected the mistake.
Now I want to install my module in order to use it, however during execution of the post installation scripts I get an error - file not found.
I have tried to find the reason for it, but the reason is quite simple, the module is not in the node_modules directory, and when npm tries to "enter" there to run the scripts, it can't find them.
I have tried to check where this is installed, but I can't.
I use npm install <user>/<repo> to install my module.

Can't run npm after installing

I've seen many similar posts on this here on SO but for some reason those solutions don't seem to work for me. Clearly I'm missing something.
I installed depcheck package globally by running npm install -g depcheck which ran fine without any errors.
If I go into the global directory for npm packages which is:
c:\Users\<Username>\AppData\Roaming\npm on my Windows 10 machine, I do see the depcheck.cmd file.
I also see the depcheck folder within c:\Users\<Username>\AppData\Roaming\npm\npm_modules folder.
I think this means I was able to install the depcheck package globally.
When I run npm config get prefix, I get c:\Users\<Username>\AppData\Roaming\npm which seems to be the correct path.
Why is it that when I run depcheck inside my project's root folder where the package.json is located, I get:
'depcheck' is not recognized as an internal or external command,
operable program or batch file
If I try another standard npm command inside my project's root folder, it works fine. For example, I ran npm -v and got the version number.
What am I doing wrong?
I also had this problem before. After searching on the web I found that reinstalling NPM with Administrator permissions worked for me, as the installer without Administrator permissions doesn't create/write to some specific files. I hope this will help for you.

Does npm delete downloaded module if the installation fails?

When I try to install something with npm it fails quite often (much more often that apt-get for example), and it will display "see log file for details" or "make in the directory failed". But when I try to inspect the directory said it will not be found. Does NPM simply delete every thing it just downloaded if anything fails during installation? Why would it tell me to check the directory then if it deleted it?
npm keeps downloaded packages as tarballs inside a cache folder.
see: https://www.npmjs.org/doc/cli/npm-cache.html
When you run npm install and something goes wrong, it will try to undo and remove the packages from your current location, but it should leave the cached tarballs alone. Sometimes the cache can have a bad package-tarball.
You can force npm to install without using the cache like this npm install --force. Or, if you really must, you can clear out the whole cache like this npm cache clean.
Remember: npm installs packages into the current folder, or wherever your package.json can be found
