'Error when I kick npm install in wsl2 ubuntu

When I run npm install, this error always happens in my project. Back then, I never found this error on any machine. But, this is my first try on WSL2 Ubuntu. Here is the error.

I have no idea what happens, I think my dev environment in WSL2 is perfect. But poor me, I was wrong. Please help me. Is there anyone who got this error too and already found the solution?

Solution 1:[1]

The solution that really worked is using nodejs version 14. I don't know why, but quasar cannot work with nodejs version 16 and newer, At least at this time.

Solution 2:[2]

Read the logs. This is a node-gyp error, which builds NPM packages when installed. On Linux, it requires GCC and Python (2). You need to have Python installed. If you already do, check if it's Python 2.
For Windows users around here, it needs Visual Studio (MVSC) and Python as well.
See the set up guide on their GitHub repo:

Quick solution for Ubuntu (as stated in OP)

Try installing the required packages:

sudo apt install python3 python-is-python3 gcc

Not-so-important notes

node-sass is depreceated, so you could perhaps try using sass.

Solution 3:[3]

I was having similar issue on wsl2 ubuntu 20.04.
Can't find Python executable "python", you can set the PYTHON env variable.

When I ran yarn install command in terminal
which is connected to wsl2 ubuntu,

  1. I was having an internet connection error. I solved it as follows:
    sudo nano /etc/resolv.conf
    and changed the nameserver to 8.8.8.8
    (This may be a temporary solution that needs to be done after reopen ubuntu)

  2. and then solved the python2 issue as follows:
    sudo apt install python2
