[Mac] 安裝 nvm 來管理不同的 Node.js 版本
今天想要來試裝 n8n 時，發現我的 Node.js 是 21.6.1 版，
結果它建議使用 18 或 20 版：
$ npx n8n Need to install the following packages: [email protected] Ok to proceed? (y) y npm WARN EBADENGINE Unsupported engine { npm WARN EBADENGINE package: '@azure/[email protected]', npm WARN EBADENGINE required: { node: '10 || 12 || 14 || 16 || 18' }, npm WARN EBADENGINE current: { node: 'v21.6.1', npm: '10.2.4' } npm WARN EBADENGINE } ^@(#########⠂⠂⠂⠂⠂⠂⠂⠂⠂) ⠙ reify:@msgpackr-extract/msgpackr-extract-darwin-arm64: timing reifyNode:node_modules/@msgpackr-extract/msgpackr-extrac npm WARN deprecated @npmcli/[email protected]: This functionality has been moved to @npmcli/fs npm WARN deprecated @azure/[email protected]: A newer major version of this library is available.

Contact Support at https://www.npmjs.com/support for more info. npm WARN deprecated [email protected]: Package no longer supported. Contact Support at https://www.npmjs.com/support for more info. Your Node.js version (21.6.1) is currently not supported by n8n. Please use Node.js v18 (recommended), or v20 instead!
要管理 Node.js 版本的話，可以在 Mac 上用 Homebrew 安裝 nvm 這個套件：
$ brew install nvm ==> Downloading https://ghcr.io/v2/homebrew/core/nvm/manifests/0.39.7 ######################################################################################################################################## 100.0% ==> Fetching nvm ==> Downloading https://ghcr.io/v2/homebrew/core/nvm/blobs/sha256:fafb27126e5f79d1b2cd4f92a47a1ef186b020be0217fd8cc79d5d12d4e64d49 ######################################################################################################################################## 100.0% ==> Pouring nvm--0.39.7.all.bottle.tar.gz ==> Caveats Please note that upstream has asked us to make explicit managing nvm via Homebrew is unsupported by them and you should check any problems against the standard nvm install method prior to reporting. You should create NVM's working directory if it doesn't exist: mkdir ~/.nvm Add the following to your shell profile e.g. ~/.profile or ~/.zshrc: export NVM_DIR="$HOME/.nvm" [ -s "/usr/local/opt/nvm/nvm.sh" ] && \. "/usr/local/opt/nvm/nvm.sh" # This loads nvm [ -s "/usr/local/opt/nvm/etc/bash_completion.d/nvm" ] && \. "/usr/local/opt/nvm/etc/bash_completion.d/nvm" # This loads nvm bash_completion You can set $NVM_DIR to any location, but leaving it unchanged from /usr/local/Cellar/nvm/0.39.7 will destroy any nvm-installed Node installations upon upgrade/reinstall. Type `nvm help` for further information. Bash completion has been installed to: /usr/local/etc/bash_completion.d ==> Summary 🍺 /usr/local/Cellar/nvm/0.39.7: 9 files, 194.2KB ==> Running `brew cleanup nvm`... Disable this behaviour by setting HOMEBREW_NO_INSTALL_CLEANUP. Hide these hints with HOMEBREW_NO_ENV_HINTS (see `man brew`).
安裝完有訊息說要修改 ~/.bash_profile，
就在裡面加入下面這幾行：
export NVM_DIR="$HOME/.nvm" [ -s "/usr/local/opt/nvm/nvm.sh" ] && \. "/usr/local/opt/nvm/nvm.sh" # This loads nvm [ -s "/usr/local/opt/nvm/etc/bash_completion.d/nvm" ] && \. "/usr/local/opt/nvm/etc/bash_completion.d/nvm" # This loads nvm bash_completion
開一個新的 shell，已經可以使用 nvm 了：
$ nvm
Node Version Manager (v0.39.7)
Note: <version> refers to any version-like string nvm understands. This includes:
- full or partial version numbers, starting with an optional "v" (0.10, v0.1.2, v1)
- default (built-in) aliases: node, stable, unstable, iojs, system
- custom aliases you define with `nvm alias foo`
Any options that produce colorized output should respect the `--no-colors` option.

用 nvm ls-remote 查詢一下目前可安裝的 Node.js 版本：
$ nvm ls-remote
......
v20.9.0 (LTS: Iron)
v20.10.0 (LTS: Iron)
v20.11.0 (Latest LTS: Iron)
v21.0.0
v21.1.0
v21.2.0
v21.3.0
v21.4.0
v21.5.0
v21.6.0
v21.6.1
來安裝 v2011.0 這個目前最新的 LTS 版本：
nvm install v20.11.0
用 nvm ls 看一下目前安裝好的版本：
$ nvm ls
-> v20.11.0
system
default -> v20.11.0
iojs -> N/A (default)
unstable -> N/A (default)
node -> stable (-> v20.11.0) (default)
stable -> 20.11 (-> v20.11.0) (default)

用 nvm use 指定現在要使用的 Node.js 版本：
nvm use v20.11.0
現在就可以正確的安裝 n8n 了：
