[tikkss]

Dear piroor.

First(#39), I tried to build the e-book on Ubuntu 18.04 LTS, but error running Node.js 18.04 LTS.

Steps to reproduce

1. Install Ubuntu 18.04 LTS on WSL 1 on Windows 10

   wsl.exe --install --distribution Ubuntu-18.04
   

2. Enter new UNIX username
3. Enter new UNIX password
4. Retype new UNIX password
5. Upgrade packages

   $ sudo apt update && sudo apt upgrade -y

6. Install required packages

   $ sudo apt install texlive-binaries texlive-lang-japanese \
                      texlive-latex-recommended texlive-latex-extra \
                      imagemagick \
                      ruby-dev build-essential

7. Install required gems

   $ sudo gem install bundler -v 2.3.26
   $ sudo gem install unicode-display_width

8. Install Node.js

   $ sudo apt install -y nodejs npm
   $ sudo npm install n -g
   $ sudo n stable
   $ sudo apt purge -y nodejs npm
   $ exec $SHELL -l
   $ node -v

Expected result

Successfully show Node.js version.

Actual result

Error running Node.js with the below command.
