dnf module list nodejs

CentOS Linux 8 - AppStream
Name Stream Profiles Summary
nodejs 10 [d] common [d], development, minimal, s2i Javascript runtime
nodejs 12 common [d], development, minimal, s2i Javascript runtime
nodejs 14 common [d], development, minimal, s2i Javascript runtime
nodejs 16 common [d], development, minimal, s2i Javascript runtime

Hint: [d]efault, [e]nabled, [x]disabled, [i]nstalled

可以看到一个有4个版本，分别是10、12、14和16，这里选择切换到最新的16版本

dnf module enable nodejs:16

命令安装

切换到16版本，然后使用下面命令安装即可：

dnf install nodejs

等待安装完成之后 ，使用下面命令验证安装是否成功：

node --version
v16.13.1

如果想安装其他版本，可以使用下面命令进行安装

curl -fsSL https://rpm.nodesource.com/setup_18.x | bash -

等repo更新完成，直接安装即可

yum install nodejs

修改国内镜像

npm config set registry https://registry.npmmirror.com

验证命令

npm config get registry

如果返回https://registry.npmmirror.com，说明镜像配置成功。

安装yarn

Yarn 是为了弥补 npm 的一些缺陷而出现的：

npm 安装包（packages）的速度不够快，拉取的 packages 可能版本不同

npm 允许在安装 packages 时执行代码，这就埋下了安全隐患

npm install --global yarn

卸载nodejs

yum remove nodejs && rm -r /etc/yum.repos.d/nodesource*.repo && yum clean all
