Ubuntu安装nvm(无需梯子自动连接github下载安装)

木法星人2025-10-25 12:59

在Ubuntu系统上安装Node版本管理器（NVM）是一个相对简单的过程。NVM允许你安装和管理多个Node.js版本,但有个墙的问题可能无法访问github.这里提供解决方法.

在Ubuntu安装NVM 5分钟搞定：

一.NVM主要用于管理Node.js版本

  1. 安装nvm
    使用nvm-sh仓库

安装nvm：

打开终端，使用我提供的代理连接github的完整安装脚本进行全自动安装,只需复制下面的脚本,保存为install.sh：

bash 复制代码 
#!/usr/bin/env bash

{ # this ensures the entire script is downloaded #

nvm_has() {
  type "$1" > /dev/null 2>&1
}

nvm_echo() {
  command printf %s\\n "$*" 2>/dev/null
}

nvm_grep() {
  GREP_OPTIONS='' command grep "$@"
}

nvm_default_install_dir() {
  [ -z "${XDG_CONFIG_HOME-}" ] && printf %s "${HOME}/.nvm" || printf %s "${XDG_CONFIG_HOME}/nvm"
}

nvm_install_dir() {
  if [ -n "$NVM_DIR" ]; then
    printf %s "${NVM_DIR}"
  else
    nvm_default_install_dir
  fi
}

nvm_latest_version() {
  nvm_echo "v0.39.1"
}

nvm_profile_is_bash_or_zsh() {
  local TEST_PROFILE
  TEST_PROFILE="${1-}"
  case "${TEST_PROFILE-}" in
    *"/.bashrc" | *"/.bash_profile" | *"/.zshrc")
      return
    ;;
    *)
      return 1
    ;;
  esac
}

#
# Outputs the location to NVM depending on:
# * The availability of $NVM_SOURCE
# * The method used ("script" or "git" in the script, defaults to "git")
# NVM_SOURCE always takes precedence unless the method is "script-nvm-exec"
#
nvm_source() {

    else
      nvm_echo >&2 "Unexpected value \"$NVM_METHOD\" for \$NVM_METHOD"
      return 1

添加执行权限:

bash 复制代码 
chmod +x install.sh
  1. 开始安装
bash 复制代码 
./install.sh
  1. 验证NVM安装

要验证NVM是否正确安装并可以正常工作，你可以运行以下命令来查看可用的Node.js版本：

bash 复制代码 
nvm list-remote
  1. 安装Node.js版本

使用NVM安装一个特定版本的Node.js，例如，安装Node.js的最新LTS版本：

nvm install --lts

截至到2025.9.8,我执行上面脚本所装的最新的LTS版本是v22.19.0 下面是安装成功的日志:

bash 复制代码 
nvm install --lts
Installing latest LTS version.
Downloading and installing node v22.19.0...
Downloading https://nodejs.org/dist/v22.19.0/node-v22.19.0-linux-x64.tar.xz...
######################################################################### 100.0%
Computing checksum with sha256sum
Checksums matched!
Now using node v22.19.0 (npm v10.9.3)
Creating default alias: default -> lts/* (-> v22.19.0)

或者你可以指定安装一个版本，比如v24.7.0：

bash 复制代码 
nvm install 24.7.0
  1. 使用特定版本的Node.js

安装完特定版本后，你可以使用以下命令来使用它：

nvm use 24.7.0

补充:

如果安装了多个Node.js版本,如何设一个默认版本?

bash 复制代码 
nvm alias default 24.7.0

这样,你打开新终端NVM会自动激活该版本的Node.js
