Cannot export org file into html. Error: make-htmlize-fstruct: Symbol’s function definition is void: record

Question

For some reason I cannot export certain org-mode files to html. Org-files without headers work fine. However, if I have a file with

#+TITLE: This is the title of my website
#+HTML_HEAD: <link rel="stylesheet" type="text/css" href="css/stylesheet.css" />
#+OPTIONS: toc:t tex:t default TOC
#+STARTUP: inlineimages
This is my personal website.

I get the following error message make-htmlize-fstruct: Symbol’s function definition is void: record, and this is the debugger result.

Debugger entered--Lisp error: (void-function record)
  record(htmlize-fstruct "#e1e1e0" "#2d3743" nil nil nil nil nil nil nil)
  make-htmlize-fstruct(:foreground "#e1e1e0" :background "#2d3743")

  org-export-dispatch(nil)
  funcall-interactively(org-export-dispatch nil)
  call-interactively(org-export-dispatch nil nil)

Note that I had to remove some portion in the middle of the output, because it was very long and it had non-ASCII characters. I was able to found a similar issue here but don't know how they solved it. My emacs version is 25.2.2 and org-mode is v9.2. I am on a Linux Mint 19.1 machine.

Using melpa requires that M-x package-reinstall RET and then type htmlize. Thanks xuchunyang
