Install node on Apple Silicon M1 both ARM and x86 (Rosetta)

00_README.md

Node.js on Apple Silicon

Node Version Manager (https://github.com/nvm-sh/nvm) works perfectly across native node installations as well as emulated Rosetta installations. The trick I am using here is to install one LTS version of node under Rosetta and another stable version as native binary.

TODO

• find a way how to run the same node version on both platforms

01_install_nvm.sh

# Run the install command from a native (ARM) terminal
# See https://github.com/nvm-sh/nvm#installing-and-updating
curl -o- https://raw.githubusercontent.com/nvm-sh/nvm/v0.37.2/install.sh | bash
# Alternatively install using brew (officially unsupported by nvm):
# brew install nvm
# Don't forget to source the command in your shell profile to make it available in new terminals!

02_install_x86.sh

# From Rosetta Terminal (tick checkbox in Terminal right click menu -> Get Info -> Open using Rosetta)
# To verify you are running in Rosetta run:
arch
-> i386

# Install node
nvm install lts/fermium

# Verify node installation
nvm use lts/fermium
node -e 'console.log(process.arch)'
-> x64

03_install_arm.sh

# From native Terminal
# To verify you are running natively:
arch
-> arm64

# Install node
nvm install stable

# Verify node installation
nvm use stable
node -e 'console.log(process.arch)'
-> arm64

04_handy_alias.sh

# To make DX a bit better you can alias your installations:
nvm alias arm stable
# arm -> stable (-> v15.6.0)
nvm alias intel lts/fermium
# intel -> lts/fermium (-> v14.15.4)

# To test aliases:
nvm use arm
# Now using node v15.6.0 (npm v7.4.0)
node -e 'console.log(process.arch)'
-> arm64
nvm use intel
# Now using node v14.15.4 (npm v6.14.10)
node -e 'console.log(process.arch)'
-> x64

I'm wrote an article after installing myself on my new Mac M1. Would love feedback on any issues etc..
https://dev.to/httpjunkie/setup-node-version-manager-nvm-on-mac-m1-7kl

The installation 01_install_nvm.sh not is the same but

I add this line in my .zprofile file
source ~/.nvm/nvm.sh

Thank you for your assistance.

Here is how to open the Terminal using Rosetta

1. Open the Applications folder in Finder.
2. Click the Search icon and type Terminal.
3. Right-click the Terminal icon that will appear and select the Get Info option.
4. From the Get Info window, check the checkbox next to Open using Rosetta.
5. Close all open windows of the terminal and quit it and then reopen the terminal again.

Anyone notice M1 doesn't run node as fast as x86? I had a machine from 2016 with far weaker specs on paper then my current machine, and my current set up does all things node related alot slower.

Could someone elaborate on line 6?
# Don't forget to source the command in your shell profile to make it available in new terminals!

Does that mean to add something to my .zshrc? If so, what exactly would I be putting there? Based on https://github.com/nvm-sh/nvm#installing-and-updating shouldn't this be added already by running the curl command?

I'm going to follow this guide, but I already have a few questions about step 1, so I'm assuming I'll run into a lot of trouble.

I'm also assuming others might have similar questions, so I'm going to read through the steps, post my questions, and then I'm going to follow the guide and try to answer them and/or post more questions.

01_install_nvm.sh

1. Do I need to uninstall anything before I do this?

Run the install command from a native (ARM) terminal
See https://github.com/nvm-sh/nvm#installing-and-updating
curl -o- https://raw.githubusercontent.com/nvm-sh/nvm/v0.37.2/install.sh | bash

2. When you say "Run the install command" are you implying that the curl -o command is the "install command"? Or are there preliminary steps I should take that I will find in "See https://github.." and therefore I should read the github link first? If so should I read the whole thing?

Alternatively install using brew (officially unsupported by nvm):
brew install nvm

3. Which one should I do? What're the tradeoffs?

Don't forget to source the command in your shell profile to make it available in new terminals!

4. What does it look like to "source the command"? I know it's source <something>, but which directory should I be in? What exactly should I source? Should I follow what @serobalino did and do source ~/.nvm/nvm.sh?

02_install_x86.sh

Install node
nvm install lts/fermium

5. What's fermium?

Verify node installation
nvm use lts/fermium
node -e 'console.log(process.arch)'
-> x64

6. Isn't fermium supposed to be "non-M1"? Is i386 "non-M1"? Why does this say x64? Isn't that the opposite of what we're trying to install?

03_install_arm.sh

From native Terminal
To verify you are running natively:
arch
-> arm64

Install node
nvm install stable

Verify node installation
nvm use stable
node -e 'console.log(process.arch)'
-> arm64

7. wait didn't we just install the M1 version of node? What's the difference between x64 and arm64? I'm assuming the latter is M1 node but then that makes me wonder why we're installing x64. I thought we were trying to install x86? What's the difference between x86 and i386?

04_handy_alias.sh

To make DX a bit better you can alias your installations:
nvm alias arm stable
arm -> stable (-> v15.6.0)
nvm alias intel lts/fermium
intel -> lts/fermium (-> v14.15.4)

To test aliases:
nvm use arm
Now using node v15.6.0 (npm v7.4.0)
node -e 'console.log(process.arch)'
-> arm64
nvm use intel
Now using node v14.15.4 (npm v6.14.10)
node -e 'console.log(process.arch)'
-> x64

8. So arm is arm64, intel is x64. And the M1 macs use which one again? Isn't one of these supposed to be x32 or i386? How does Rosetta fit into all of this?

Okay, I've overwhelmed myself so I won't answer all my own questions, but I did manage to follow this guide successfully, so here are a few answers:

1. no I didn't need to uninstall anything
2. yes, curl -o- https://raw.githubusercontent.com/nvm-sh/nvm/v0.37.2/install.sh | bash is the install command, I verified that by reading the link, and it worked out for me
3. I read something somewhere about using brew not being a good idea, so I used the curl command.
4. what @serobalino did worked for me: source ~/.nvm/nvm.sh
5. fermium is just a name for a version of node
6. Fermium is non-m1 (x86_64), i386 is also non-M1, we want to install x64 version because that's the version of node we will run with Rosetta.
7. now we are installing the m1 version. x64 is non M1, arm64 is M1. we are not trying to install x86 because that's 32bit and i have a 64 bit OS. the difference between x86 and i386 is irrelevant to me now
8. M1 macs use arm64, Rosetta will allow us to run x64 (non-M1)

These instructions seem to have worked for me but I'm still not able to connect to an oracledb using my M1 Mac. I created this simple repo. If anyone is willing to take a look and tell me where I'm going wrong, I would really appreciate it.

Update: I was able to resolve the issue and will update the repo I linked in the next few days.

This super helpful and tricky thank a lot.

thanks a lot brother!

@GoonerBrian Thanks a lot brother, I've been trying to fix this issue for the past 12hrs in my mac m1. Nothing really worked until i saw your repo. I really appreciate it❤️, its 3am here I can finally sleep now!!

@AmrMekkawy glad I could help! Sleep well.

Thank you, working expected.

As a note, this is not needed if you are installing node 16+
