CentOS - node command not found to solve

background:

A few days ago Ali cloud has deployed a project node, node version v12.10.0

Each re-connected to the remote input node -v / pm2 -v display command not found;

Every time you must enter nvm use v12.10.0, you can use the normal use of node / pm2

 solve:

Queries whether node

echo $PATH     //查看是否有/usr/local/bin。
ls -l /usr/local/bin | grep node     //看看node是否确实存在。
ls -l /usr/local/bin/node            //同上

 

Create a soft associative link (shortcut similar to the Windows)

Enter the command: to create a soft link to  usr / local / bin / / node  down

[root@xxx ~]# which node
/root/.nvm/versions/node/v12.10.0/bin/node
[root@xxx ~]# ln -s /root/.nvm/versions/node/v12.10.0/bin/node /usr/local/bin/node

---

So each node command after the connection has, however, there is a problem, nvm points to the system, do not know if every point v12.10.0 ?, chiefs seek correction

[root@xxx ~]# nvm ls
       v12.10.0
->       system

---

Tip：

1. Soft links, has been flashing red question: in all likelihood be a reference path error
2. Delete soft link: Enter the directory soft link RM -rf ./node (delete soft links, but does not delete the actual data), do not use the RM -rf ./node/  (this will be the contents of the original node deleted)
3. Find the node directory: the Find -name 'v12.10.0'
