How to run a NodeJS version for Intel on mac M1?

Question

At first I had problems with running Node natively on my M1 machine. After installing NodeJS v15 through NVM I was able to compile my application for arm64(apple silicon) with no problem.

How could I switch back to installing NodeJs for Intel, so I can build my projects for both M1 and Intel on the same machine?

I tried reverting to a NodeJS version before v15, but that did not work when compiling.

Try:

• Before installing the older node version with nvm we need to change zsh to work in x64 arch.

arch -x86_64 zsh

• Checking node -p process.arch then output x64 instead of arm64. means it able to run with rosetta 2.
• After installing it, change zsh back to arm64

arch -arm64 zsh

• Rerun the lerna job and it's working normally. Each cpu monitored work averaging 40%, the temperature is normal (below 50 C), all job is marked as intel and the job done around 20 minutes (as expected).
