Problem met when installing Quasar-cli on CentOS

[xinweiHE]

I tried to install Quasar-cli on CentOS and failed. Related code is as follow.
May anyone help me… Usually I work on Ubuntu and I am not so familiar with CentOS.
Thanks a lot!
(I installed nodejs by downloading source code from https://nodejs.org/dist/v8.11.3/node-v8.11.3.tar.gz and using sudo make install.)

I have solved this problem by re-installing nodejs.
I downloaded Linux Binaries (instead of downloading Source Code and compiling it with my computer) this time, and the installation was perfect.
Maybe there was something wrong in my previous nodejs installation method. XD

I found it helpful, when using nvm to do the following:
nvm alias default v8.11.1
