Installing Tailwind to Ruby on Rails 6 | The engine "node" is incompatible with this module

Question

When installing Tailwind-CSS, I ran this command

yarn add tailwindcss@npm:@tailwindcss/postcss7-compat postcss@^7 autoprefixer@^9

I got this error message, which tells me to update node to a compatible version.

**error** tailwindcss@2.1.2: The engine "node" is incompatible with this module. Expected version ">=12.13.0". Got "10.24.1"

So how do I update node properly? I am using Ruby on Rails 6

Update

When I updated node, I ran into a subsequent problem. This is what I ran to update node

nvm install 12.22.1

Now when I try to install Tailwind-CSS, I get a different error message.

Command 'yarn' not found

So then I ran nvm use 10.24.1 and I am back to square one.

Answer 1

When you install via yarn, append

--ignore-engines 

So the full installation command is

yarn add tailwindcss@npm:@tailwindcss/postcss7-compat postcss@^7 autoprefixer@^9 --ignore-engines

I don't know why this works, but it does
