解决方法：

方式一（推荐）：用 nvm 管理 Node

1️⃣ 安装 nvm

curl -o- https://raw.githubusercontent.com/nvm-sh/nvm/v0.39.7/install.sh | bash

然后：

source ~/.bashrc

---

2️⃣ 安装 Node 20

nvm install 20 nvm use 20 nvm alias default 20

---

3️⃣ 确认版本

node -v

应该看到：

v20.x.x

export NVM_DIR="$HOME/.nvm"
[ -s "$NVM_DIR/nvm.sh" ] && \. "$NVM_DIR/nvm.sh"
[ -s "$NVM_DIR/bash_completion" ] && \. "$NVM_DIR/bash_completion"

然后安装：

nvm install 20
