I've installed meteor on my machine:
curl https://install.meteor.com/ | sh
My understanding is that it meteor runs off of node.js and automatically installs it. And node automatically installs npm.
I'm working through the Discover Meteor tutorial and it has me run:
npm install -g mup
But I get the following output:
-bash: npm: command not found
Do I need to run it from a different directory? Or download / install something extra onto my machine. Add it to my PATH?
When you install Meteor, it does not automatically install node && npm. When installing Meteor, it will download something called dev_bundle which has NodeJS and all the NPM modules needed by Meteor. All these modules are pre-compiled for your platform but are not "installed" per-se.
Check out this post if you want to use the node distribubtion included with Meteor: https://meteorhacks.com/how-meteor-uses-node. I suggest you just install Node on your own, though.

I need some help and clarification regarding Yarn installation process.
MacOS ver. 10.14.2
I've installed Homebrew via official site (ver. 2.0.1).
I've installed NPM by downloading package from official site (ver. 10.15.1 LTS).
Now when I tried to install yarn via brew install yarn
I have the following error:
The post-install step did not complete successfully
You can try again using `brew postinstall node`
As I undertand, NPM installs node locally, when, for instance, I try to use create-react-app. When I use Homebrew to install yarn, it tries to install node globally. And we have conflict here.
I've found suggestion to use:
sudo chown -R `whoami`:admin /usr/local/
I am not entirely sure what this command does.
So, the questions are:
Why changing the owner of the folder should be a solution? How will it affect multi user system?
What is the correct way to install yarn?
Can be there any conflicts if node is installed globally and locally (app folder.)
P.S. Please correct me, if I have wrong understanding here.
As Trott points out, npm does not install Node. npm is a package manager that comes bundled with Node. If you install Node, you automatically install npm.
Why changing the owner of the folder should be a solution? How will it affect multi user system?
It's not. Changing the permissions of this folder is sometimes suggested as a workaround for when you have npm installed in a location owned by root. This can cause EACCES errors when you try to install packages globally.
What is the correct way to install yarn?
While you can install Yarn through the Homebrew package manager, I would recommend doing: npm install -g yarn.
Can be there any conflicts if node is installed globally and locally (app folder).
You can't install Node globally and locally. You can install multiple versions of Node on the same machine, however.
I'm not a big fan of having one global Node installation, as it makes it a pain to update (esp. if one application relies on an older version of Node) and, depending on how you install Node, it can lead to permissions errors.
The better way is to use a version manager. This will allow you to install multiple Node versions on your machine, avoid permissions errors and swap between these Node versions at will.
I would recommend using nvm. It works nicely on MacOS. The TL;DR for installing nvm is:
curl -o- https://raw.githubusercontent.com/creationix/nvm/v0.34.0/install.sh | bash
But I would encourage you to look at the project on GitHub and read its README. There is also a good tutorial on how to use it here.
Once you have Node installed using nvm, run npm install -g yarn to install Yarn globally and you should be off to the races.
Finally, you might want to read this tutorial on using npm, as it could help to clear up some of the concepts.
HTH
I have faced a problem after install yarn by running npm install -g yarn command in my OS Windows 10 Pro. That was showing yarn' is not recognized as an internal or external command operable program or batch file.
Whatever, I have found the solution:
After npm,
go to CMD from your windows PC,
write : *npm install -g yarn*
then,
Go to Environmental Variables set up.
Edit Path and add new and paste:
C:\Users\User\AppData\Roaming\npm\node_modules\yarn\bin\
Restart your terminal. And then check again in your cmd by running :
*yarn* or *yarn --version*
After installing node via npm , using 'nvm ls' gives the version which i have installed like v8.9.4 and also node -v also shows the version. But at the same time, when checking for 'nodejs --version' tells me to install node js as 'sudo apt-get install nodejs'.
Via npm or nvm Node.js is called node but if you install via apt-get you need to use the package name nodejs because via apt-get node is a package name take by a completely different application that happens to also be called node.
what are the differences between node.js and node?
I'm building new React App to learn and play with Draft-js, RichStyle Text Editor.
I used create-react-app to initialize my React application. It's working, and very easy to use.
Now, I tried to add semantic-ui-react, which is React version of SemanticUI lib.
Aaaaannd fail.
npm install semantic-ui-react --save
As you can see, same effect for draft-js.
My issue is that normally there's no problem to use draft-js & semantic-ui-react with React 15.4.2. I use this stack in professional env.
Is there something I'm missing with npm ? Is create-react-app can stop this install ?
Now, I can't install any packages. This error shows up everytime. But, I cant still npm start for my local web server. I also tried npm cache clean
Is my very simple package.json
Thanks again for you help.
Solution : Just update NPM and everything working.
Edit : My App folder :
And my npm & node version
My guess is that you have old npm or node versions, you can't start the project with this versions... you can upgrade npm and node programs.
if you are using brew on OSX then you can use following commands to upgrade them.
brew update
brew upgrade node
npm install -g npm
In the Bootstrap documentation after Node.js and Grunt have been installed they say I have to :
Navigate to the root /bootstrap/ directory, then run npm install
What's that mean? I've open a folder with Bootstrap source files but how am I supposed to "run npm install'? I am totally confused.
If you haven't done so, download and install Node.js. The process varies per platform, so refer to the download link.
Once you've installed Node.js, you may need to open a new shell or even reboot for the any new environment variables to take affect.
Once you have Node.js installed, you should be able to:
cd ./bootstrap
npm install
I've installed NVM for node.js using the instructions from this post:
http://www.backdrifter.com/2011/02/18/using-nvm-and-npm-to-manage-node-js/
When I switch between node versions and then use npm to install a module, all the modules are placed in the same 'node_modules' folder (~/node_modules/) instead of in the 'node_modules' directory specific to that version of node?
Any idea on how to remedy this?
Based on the comments from https://github.com/creationix/nvm/pull/97:
When installing packages with npm using the global switch -g the
package ends up in the proper directory (i.e.
.nvm/$VERSION/lib/node_modules), however node is unable to require it
since it somehow isn't searching on it's prefix.
So using npm install -g xxxxx will put the modules in the correct location for NVM but if you try to require one of them node can't find the module. I am still playing around with this and will update if I find a solution.
Update
Where does NPM put node_modules? (see https://docs.npmjs.com/files/folders)
Local install (default): puts stuff in ./node_modules of the current package root.
Global install (with -g): puts stuff in /usr/local or wherever node is installed.
Install it locally if you're going to require() it.
Install it globally if you're going to run it on the command line.
If you need both, then install it in both places, or use npm link.
So what I did was run npm init (see http://npmjs.org/doc/init.html) in my projects root dir which generated package.json. Now when I run npm install xxxxx it creates a node_modules dir in my project folder (which I add to my .gitignore). This works for modules that I require in my code.
For commands such as CoffeeScript I install with npm install -g coffee-script which puts it in the correct directory (.nvm/$VERSION/lib/node_modules). While I can't require these modules (npm link should solve this problem) I can run the commands - i.e. coffee.
I just installed express globally (-g) and was having problem when require("express"). Just like Jesse Vogt said I just reinstalled express but this time without the -g just like this: "sudo npm install express" and now is working perfectly!
For latest nvm window version 1.1.7.
Package was installed and placed into the respective nodejs version.
nvm use 16.8.0
npm install truffle
nvm use 16.7.0
npm install mysql
