I have a project that depends on nodegit.
When I run
npm install -g .
I get this output at some point:
When npm finishes installing, I lose access to it in the path:
I end up having to run 'n', to change to a previous version of node, then run 'n' again to change to the latest version of node and in the end run 'npm install -g npm#latest' to get the latest version of npm.
It looks like you are trying to install NodeGit. (Or maybe you are installing something that depends on NodeGit?) Assuming you are installing NodeGit, that is not a CLI tool and should not be installed globally. It installs npm as a dependency. Your installation is failing for whatever reason, and as part of cleanup, it is uninstalling npm.
If you are installing NodeGit, do not install it with -g.
If you are trying to install something that isn't NodeGit, you need to either change directories to that project folder or (more likely) change your installation command line.
If you are installing something that depends on NodeGit and really should be installed globally, you'll need to identify why your installation is failing (which it appears to be failing at the pruning of dev dependencies, but I can't tell why from the output--might be file permissions, might be something else). As long as NodeGit installation fails, it will unbuild npm.
This is actually an issue with the nodegit project.
You can follow it in https://github.com/nodegit/nodegit/issues/561 which led to https://github.com/nodegit/nodegit/issues/567
Nothing i can do but wait.

I've installed node.js v8.11.3 from their website, and it comes with npm v5.6 built-in.
Those files are in my "program files\nodejs" folder.
But recently I got aware that I can run:
npm install -g npm #"some version (upgrade or downgrade)"
and another version will be installed globally and those files will by in my "%appdata%\npm\node_modules\" folder.
Question1:
If I do this, what happens when I run the next npm command on VSCode Terminal? Which version would I be using then? Will the global version override the buil-in version?
Question 2:
And also, what happens if I install npm locally in one of my projects? Does the local version alsos override the built-in version? Does it override any global version as well?
Question 3:
It feels weird to use npm to install npm. Is this common?
Thanks.
Question 1: If I do this, what happens when I run the next npm command on VSCode Terminal? Which version would I be using then? Will the global version override the built-in version?
When you install software on Windows and attempt to use a command from the console, it takes the name of the command you're running and looks in your Windows' PATH Environment Variable for the list of folders to look for when you run a command. If you were to run npm install -g npm like you said, the version of NPM you ran when it came to your terminal would be the first version that appears in your PATH Environment Variable.
Question 2: And also, what happens if I install npm locally in one of my projects? Does the local version also override the built-in version? Does it override any global version as well?
Since your PATH Environment Variable likely doesn't extend to the node_modules folder in your project, it likely wouldn't change anything. Locally installed node modules are local in nature, meaning they rarely interact with anything outside of their folder, they have to be called.
Question 3: It feels weird to use npm to install npm. Is this common?
I can't say it is common. I doubt most node developers install npm on its own very often. And if they do, they likely don't do it through an already working npm. However, you can update all of your installed packages through npm, including npm itself, using npm update.
Basically according to the doc i would have one answer for the two questions :
If you’re installing something that you want to use in your program, using require('whatever'), then install it locally, at the root of your project.
If you’re installing something that you want to use in your shell, on the command line or something, install it globally, so that its binaries end up in your PATH environment variable.

So I'm trying to get myself a good Discord Selfbot and one of them requires nodejs, then it said to do npm install. But it gave me an error. I tried again again again and again but nothing worked. The latest thing I did was installing nodejs via scoop but I get this error trying to install npm. Is there a way to do this manually or something? I've tried installing different versions but nothing. I believe scoop installed the latest version.
Here's the image. (the red squares cover up just names)
You have npm already installed, seems that the problem is you don't have a package.json in that location. It says ENOENT: No such file or directory
You already have npm installed! npm is a package manager for installing nodejs packages. Try running some nonsense command (like "lkajshdflhsf") and you'll see what it looks like if you actually didn't have npm installed. What npm install does is install some package. So, for example, if you want to install a node package called Blah, you would run npm intall blah.
I just setup a test, and tried to npm install express even though express already exists globally on my system. To my surprise, instead of using the global version, it ended up re-installing a version locally!? Isn't it supposed to use the global version... Or am I suppose to use -g every time, even when I only want to use the existing global version. Otherwise, what's the point of installing anything locally!?
The answer is "NO". It isn't supposed to use your global version.
If you want to use your global version, then you doesn't need to execute npm install at all because it is already installed.
If you do it then, obviously, you are saying "I want to install it locally to my project". And more than that: "I want to install its latest version unless it is declared in my package.json with other explicitly specified version".
In fact, the actual question is: Why in the hell would you want to not install a dependency of your project locally? To have more version mismatch issues?
As #anshuman_singh says, best practice is to always do an npm install --save.
You are able to use globally installed packages, of course. It could be handy for fast testing code that you will drop just after a few hours or so.
But, anyway: If you doesn't have really hard disk or network bandwidth issues, installing all dependencies locally will avoid you too much trouble in the future.
On the other hand, uploading that modules to your code repository is also a bad idea (maybe that is what you were trying to avoid) because, with different versions of node, most native modules won't work if not rebuild. But most VCS support ignoring files and or directories that must not be uploaded.
For example, in git (.gitignore file):
**/node_modules
In summary:
npm init (if you didn't already it).
npm install --save for all your project dependencies.
npm install --save-dev for dependencies not needed in production (testing stuff).
Don't upload node_modules to your VCS.
After new checkout: npm install or npm install --production (to not install dev-dependencies).
npm install -g only for tools you will use in console.
This way, you are sure that you will have in production (or other dev environments) the exact same version of each package.
And, finally, if you ever want to upgrade some package to its latest version, simply run:
npm install --save <pagkage_name>#latest.
If you’re installing something that you want to use in your program, using require('whatever'), then install it locally, at the root of your project.
If you’re installing something that you want to use in your shell, on the command line or something, install it globally, so that its binaries end up in your PATH environment variable.
The first option is the best in my opinion. Simple, clear, explicit. The second is really handy if you are going to re-use the same library in a bunch of different projects
Install locally-
npm install moduleName
install locally and save in package.json-
npm install moduleName --save
install globally-
npm install moduleName -g
searched, and did not see this specific problem.
Trying to get a MEAN stack built on my Linux Mint machine, and bumping into a bit of an unusual issue.
Got MongoDB installed, and finally got it running correctly (none of the instructions ANYWHERE mentioned having to create the /data/db/ directory and set permissions, go figure).... it works now.
Got NodeJS installed, and it appears to work correctly.
I had been told (apparently incorrectly) that NPM installs right alongside Node, with:
sudo apt-get install nodejs
but:
$ npm
bash: /usr/bin/npm: No such file or directory
So I go ahead and install NPM separately.
$ sudo apt-get install npm
Seems to work, so far, no errors, and it looks like it is pulling down the NPM package and installing it...
$ nodejs -v
v0.10.21
$ npm -v
$
?? It simply fails to respond without any error... so I try:
$ npm install grunt -g --save-dev
$
Same completely silent failure... in fact, NOTHING I could do gets a response out of NPM.
Looked all over the web, and saw nothing similar anywhere... found out that NPM holds its cache files in ~/.npm and noticed that this folder didn't exist (kinda like the mongo issue above), so I created it, and set permissions to 7777... still nothing.
Purged and re-installed both node and npm, tried installing them both together and separately (yes, desperation)... still no love.
WTF am I doing wrong?
I would love, eventually, to have a nice development environment setup, hopefully with Cloud9 as a local IDE.... but already pulling my hair out.
=========================================================================================
OK, after a few more headaches, this is up and built now... thank you all.
Would love to mark both as answers, but it won't let me.
npm does come with node. Where is apt-get pulling it from? I install the Mac OS X packages on my Mac for development and npm does in fact come with it. I compile from source on my CentOS server and npm comes with it.
Your package provider may be providing them separately as a (in)convenience to you.
As for why your npm command does not work after installation, I can't say for sure, but I am suspicious of your use of --save-dev and -g together.
-g means to install globally, which means 2 things:
It will be installed outside of your npm package's structure into a system location like /usr/bin or /usr/local/bin
It requires root access to install. Did you use sudo to run it with root access?
Both of those requirements conflict with --save-dev which records the package as a dependency in your package.json file so that future npm install commands will install that package within the project space.
That said, I happen to know a lot about grunt. It has 2 parts, a globally installed tool and the package-specific tool. The correct way to install it is:
$ [sudo] npm install -g grunt-cli
$ npm install grunt --save-dev
This will install the grunt-cli package into a system location guaranteed to be in the $PATH, which turns around and looks for a package-specific grunt installed which is not system-wide.
When installing nodejs with npm, this one-liner worked for me.
sudo apt-get install nodejs nodejs-dev npm
I don't believe npm comes with the nodejs installation in the apt repo. Try to install npm separately using the following tutorial http://www.giantflyingsaucer.com/blog/?p=1688 'To install NPM ....'
====== Edit ====
node and npm IS separate. Follow the official wiki and everything should be fine
Node noob here.
I had previously installed both npm and node separately.
Apparently, npm comes with node now. (link)
To my newbie mind, this means my previous dual installation is old and ugly. 1 binary > 2 binaries. So i uninstalled both.
Then I installed the latest node following the procedure. (i am running eOS)
Terminal
user#box:-$ which node
/usr/bin/node
user#box:-$ node -v
v0.10.22
user#box:-$ which npm
user#box:-$ npm -v
bash: /usr/bin/npm: No such file or directory
I can always run:
curl https://npmjs.org/install.sh | sh
but that seems to indicate that npm is actually NOT included in node.
When they say they are included do they just mean the code is in the same repo, but the binaries are still different?
Final question I have /usr/bin/node as well as /usr/bin/nodejs
can i delete one of these? im not sure when/where i picked up a second copy.
Yes, the nodejs package includes both node and npm executables. The code for each has its own repo, but when packaged both are included.
npm source: https://github.com/isaacs/npm
node source: https://github.com/joyent/node
When you install that .deb file from the PPA, you should get both /usr/bin/nodejs and /usr/bin/npm and 2 symlinks at /usr/bin/node (which points to) /etc/alternatives/node (which points to /usr/bin/nodejs).
If any of this isn't true, your install didn't fully succeed, most likely due to conflicting files you left around from your manual install. I would suggest uninstalling the .deb then making sure there are no stale files left from your manual install and then installing again.
Only node.js packages comes with npm. so if you are installing using an .msi, .exe, .dmg .pkg, .deb or using a package installer like apt-get, yum or brew, then you'll have both node and npm.
However,npm is not part of the node core. if you are installing node and using a method where you are using ./configure or make install || make link, then npm will not be installed, and will need to be compiled using the same type of installation, and node will have to be placed on your path.
If you used git, or unzipped node and you can see a configure script, then you will also need to acquire npm.
I've had issues (mostly on Mac) with npm ending up in directories that aren't in the terminal PATH. If you can figure out where npm is located, you can just add it to your path with something like:
export PATH=$PATH:/path/to/npm
I think (I'm not on a mac so I can't check at the moment) that it sometimes gets put in /usr/local/share/. But at any rate, the problem is likely NOT that npm isn't installed, but that it's installed somewhere you're not expecting.
Few months ago i had started learning the react so all this stuff i needed to install my laptop that had the ubuntu operating system.
What i did -- First i installed the node and without knowing that it came up with the npm package. I installed the npm package again.. but there was no conflict at all.
But after exploring all these things that nodejs have npm package. So i uninstalled the npm package due to concern about memory usage..
And Now everything is working fine....
