首先要确定自己要安装的版本,这里以16.12.0
版本为例
-
访问 https://nodejs.org/zh-cn/download/releases/
-
点击下载后,会弹出一堆内容,选择自己需要的即可
-
建议下载 tar.gz 后缀的这个,因为可能有的是 tar.xz 后缀的,区别在于解压的方式不一样,但是我比较习惯tar.gz的。
下载链接: https://nodejs.org/download/release/v16.12.0/node-v16.12.0-linux-x64.tar.gz -
上传到linux后,解压即可,这里我们指定解压到
/usr/local/
目录下
tar -zxvf node-v16.12.0-linux-x64.tar.gz -C /usr/local/
- 改一下文件夹的名字,我只是觉得太长了,如果不想改可以忽略这一步
mv /usr/local/node-v16.12.0-linux-x64 /usr/local/node-v16.12.0
- 创建软连接,因为我们改过文件夹名称了,所以这里是
node-v16.12.0
,如果没有改或者改成了其他,记得相应改动自行匹配一下。
ln -s /usr/local/node-v16.12.0/bin/node /usr/local/bin/
ln -s /usr/local/node-v16.12.0/bin/npm /usr/local/bin/
ln -s /usr/local/node-v16.12.0/bin/npx /usr/local/bin/
- 最后测试一下
[root@lazyfennec local]# node -v
v16.12.0
[root@lazyfennec local]# npm -v
8.1.0
[root@lazyfennec local]# npm -v
8.1.0
[root@lazyfennec local]#
添加一个cnpm指向国内的淘宝镜像
- 执行以下命令
npm install -g cnpm --registry=https://registry.npm.taobao.org
此时还是无法使用cnpm 的,但是我们会发现在 /usr/local/node-v16.12.0/bin/
下已经存在了一个cnpm
,那么同上,我们创建一个软连接就好了。
- 创建软连接
ln -s /usr/local/node-v16.12.0/bin/cnpm /usr/local/bin/
这个时候我们就可以测试一下cnpm了
[root@lazyfennec bin]# cnpm -h
