I'm on Ubuntu 20.04.

I saw this answer: https://superuser.com/a/902150/425838

Tried to install:

$ npm install -g markdown-pdf

Failed, so I used sudo:

It seems to have worked:

$ sudo npm install -g markdown-pdf

I tried to use it. Failed!

Here's my test.md file I was trying to convert to pdf:

Snippet from: https://github.com/ElectricRCAircraftGuy/eRCaGuy_hello_world/blob/master/markdown/github_readme_center_and_align_images.md

## 1.1. Align images left, right, or centered, with NO WORD WRAP:

This:

```html
**Align left:**
<p align="left" width="100%">
    <img width="33%" src="https://i.stack.imgur.com/RJj4x.png"> 
</p>

**Align center:**
<p align="center" width="100%">
    <img width="33%" src="https://i.stack.imgur.com/RJj4x.png"> 
</p>

**Align right:**
<p align="right" width="100%">
    <img width="33%" src="https://i.stack.imgur.com/RJj4x.png"> 
</p>
```

Produces this:

**Align left:**
<p align="left" width="100%">
    <img width="33%" src="https://i.stack.imgur.com/RJj4x.png"> 
</p>

**Align center:**
<p align="center" width="100%">
    <img width="33%" src="https://i.stack.imgur.com/RJj4x.png"> 
</p>

**Align right:**
<p align="right" width="100%">
    <img width="33%" src="https://i.stack.imgur.com/RJj4x.png"> 
</p>

If you'd like to set the text itself to left, center, or right, you can include the text inside the `<p>` element as well, as regular HTML, like this:

```html
<p align="right" width="100%">
    This text is also aligned to the right.<br>
    <img width="33%" src="https://i.stack.imgur.com/RJj4x.png"> 
</p>
```

I have encountered the same problem, and I got the output PDF with nothing, which cannot be opened:

@alanshaw Could you give us some advice, please?

FYI all: here's my current workaround to convert markdown to PDF:

Summary of that answer: don't use markdown-pdf at all.

Instead:

  1. Use the Markdown Viewer plugin in Chrome.
  2. Use pandoc. See my answer here:
    pandoc -f gfm -t html5 --metadata pagetitle="test.md" --css github.css \
    test.md -o test.pdf

Thank you for the guidance, but I cannot find any practical solutions for this problem in the community you have provided.

I've updated my comment. Does it make more sense now?
