node多版本管理 fnm使用

安装

win11

winget install Schniz.fnm

# 安装执行命令 否则终端找不到node npm 也不能使用fnm use
fnm env --use-on-cd | Out-String | Invoke-Expression

# 配置node下载加速 powersell 或者自己加环境变量
[Environment]::SetEnvironmentVariable('FNM_NODE_DIST_MIRROR', 'https://npmmirror.com/mirrors/node', 'User');

使用

#查看可安装的 Node.js 版本。
fnm list-remote fnm ls-remote
#查看目前已经安装了的node版本：fnm ls
#安装node 具体版本
fnm install v16.18.1
#安装最新LTS版本
fnm install --lts
#安装的版本最新的大版本
fnm install 24
#卸载
fnm unstall 24
#默认使用
fnm use 24

进入项目自动切换 node 版本

配置好环境变量之后，在项目根目录创建 .node-version 或者 .nvmrc 文件，进入项目目录后即可自动切换设定好的 node 版本。

22.17.1

webstrom 自动识别 node 路径

## 终端执行命令
[Environment]::SetEnvironmentVariable('Path', [Environment]::GetEnvironmentVariable('Path', 'User') + ";$env:APPDATA\fnm\aliases\default", 'User')

Linux安装

使用下面的安装脚本安装执行命令

主要使用gitea actrunner ci/cd的把actrunner 进程杀掉重启否则不识别fnm
gitea actrunner的执行用户取决于谁把它启动的一般和root一样

## 安装
~/fnminstall.sh -d /usr/local/fnm

## /root/.bashrc新增下面的东西
FNM_PATH="/usr/local/fnm"
if [ -d "$FNM_PATH" ]; then
  export PATH="$FNM_PATH:$PATH"
  eval "`fnm env`"
fi
## 刷新
source ~/.bashrc
## 新增 /etc/profile.d/fnm.sh 写入以下内容
cat >/etc/profile.d/fnm.sh <<'EOF'
#!/bin/sh
export FNM_DIR=/usr/local/fnm
export PATH="/usr/local/fnm:$PATH"
eval "$(fnm env --use-on-cd)"
EOF
chmod 644 /etc/profile.d/fnm.sh
source /etc/profile.d/fnm.sh




## 处理非root用户报错Can't create the symlink for multishells at "/run/user/0/fnm_multishells/35677_1757075243053".
## Maybe there are some issues with permissions for the directory? Permission denied报错

## 使用root 命令提前安装node 因为其他用户会出现没有权限的情况

## 查看其他用户id 我的git是105
id -u

## 安装目录
mkdir -p /run/user/105
chown git:git /run/user/105
chmod 700 /run/user/105

## 切换到其他用户 CI/CD用户
su git 
cd ~/
## 在~/.bashrc新增下面的东西
export XDG_RUNTIME_DIR=/run/user/$(id -u)
FNM_PATH="/usr/local/fnm"
if [ -d "$FNM_PATH" ]; then
  export PATH="$FNM_PATH:$PATH"
  eval "`fnm env`"
fi
## 生效
source ~/.bashrc
## 执行
eval "$(fnm env --use-on-cd)"
