얼마 전에 Homebrew와 함께 노드와 npm을 설치했지만 npm 명령을 찾을 수 없음 오류가 계속 실행될 때까지 둘 다 잘 작동했습니다. $ whereis node를 실행하면 아무것도 얻지 못합니다. Homebrew is a Unix-like package manager that should have been included in the original version of MAC OS X but was not. NPM is a set of web dev libraries for Node, JS.
Node version manager is a script to manage multiple active node.js versions. And I usually install most applications using homebrew.
NOTE:install NVM with Homebrew is not officially supported.
Homebrew Npm Update
So these are the steps to install NVM with Homebrew:
- Install NVM with Homebrew
Install NVM is very easy just with this command:
- First setup
The first thing we need to do is create a folder for the current user.nvm
where the files will reside.
- Install a node version
There are different node versions that you can install; if you want to install the last version is very simple just using the command:
But I work with the long-term support version and the command to install the last LTS version is the command below:
- Start using the node version installed with NVM
After you installed the node version that you are looking it will be active after this command:
The previous command is also useful if you want to change from different Node.js versions.
To check if everything is working as expected the command bellow print the node version:
Finally, we want to execute NVM in every shell session, so let's create two user environment variables NVM_DIR
and NVM_HOMEBREW
.
Generally, environment variables are going in the file ~/.bash_profile
if you are using BASH or in the ~/.zshenv
file if you are using ZSH, but it will work also if you want to put the code below in the file ~/.bashrc
for BASH or ~/.zshrc
for ZSH.
You can use '$(brew --prefix nvm)/nvm.sh'
instead of '/usr/local/opt/nvm/nvm.sh'
but it will be slower.
Homebrew Npm Path
The NODE_PATH
variable can also be useful for some applications, for example, VScode, this is the code you need to put after the previous variables.
Hi! Durametric usb devices driver download. I am new to packages and just want to be sure on what's going here.. I installed homebrew, npm and node at my mac with the terminal following this guide: https://treehouse.github.io/installation-guides/mac/node-mac.html
Is homebrew, npm and node saved just as files in finder? Or are they programs that should be among applications? For example I can't see home brew anywhere except when I used it in the terminal.
When I search for npm on my computer I find 2 files called node_modules. One in the file flashcards and one in the file Debug node Applications with VS code (both are downloaded from courses at treehouse). Is this the npm-package? Why is it at 2 places? Since I am done with these courses I want to delete those files - is that 'ok'?
Bonus question: I installed Xcode because I read had to have that for installing the other stuff.. and it is saved as a program. But I am not sure on when or how to use Xcode?
To locate homebrew, npm and node try the which
command in terminal. For example I used which brew
and found
which is an alias for
Here is the npm doc for folder use and the npm doc for install. For local installs packages are installed in the node_modules folder in the project folder. So each project will have its own local node_modules folder. You should be able to delete the project folder if no longer needed.
Files installed with Xcode are used by other applications. You don't have to learn or use Xcode yourself.
