==> Installing dependencies for node: brotli, c-ares, icu4c, libuv, jemalloc, libev, openssl@1.1 and nghttp2
==> Installing node dependency: brotli
==> Pouring brotli--1.0.9.arm64_big_sur.bottle.tar.gz
🍺  /opt/homebrew/Cellar/brotli/1.0.9: 25 files, 2.3MB
==> Installing node dependency: c-ares
==> Pouring c-ares--1.17.1.arm64_big_sur.bottle.tar.gz
🍺  /opt/homebrew/Cellar/c-ares/1.17.1: 85 files, 693.8KB
==> Installing node dependency: icu4c
==> Pouring icu4c--68.2.arm64_big_sur.bottle.tar.gz
==> Caveats
icu4c is keg-only, which means it was not symlinked into /opt/homebrew,
because macOS provides libicucore.dylib (but nothing else).

..

==> openssl@1.1
A CA file has been bootstrapped using certificates from the system
keychain. To add additional certificates, place .pem files in
  /opt/homebrew/etc/openssl@1.1/certs

and run
  /opt/homebrew/opt/openssl@1.1/bin/c_rehash

openssl@1.1 is keg-only, which means it was not symlinked into /opt/homebrew,
because macOS provides LibreSSL.

If you need to have openssl@1.1 first in your PATH, run:
  echo 'export PATH="/opt/homebrew/opt/openssl@1.1/bin:$PATH"' >> ~/.zshrc

For compilers to find openssl@1.1 you may need to set:
  export LDFLAGS="-L/opt/homebrew/opt/openssl@1.1/lib"
  export CPPFLAGS="-I/opt/homebrew/opt/openssl@1.1/include"
