`mix tailwind default` exists with 137

[JosephShering]

Command: mix tailwind default

Output: ** (Mix) mix tailwind default exited with 137

Platform: Mac OS X (13-inch, M1, 2020) Memory 16GB

Mix Tailwind Version: {:tailwind, "~> 0.1.5", runtime: Mix.env() == :dev}

Mix Config Setup:

config :tailwind,
  version: "3.0.10",
  default: [
    args: ~w(
      --config=tailwind.config.js
      --input=css/app.css
      --output=../priv/static/assets/app.css
    ),
    cd: Path.expand("../assets", __DIR__)
  ]

Can you try bumping tailwind version to latest? (3.0.24) . I don't have an M1 architecture to test on, so hopefully the latest build will resolve whatever issues you're hitting

[JosephShering]

This is my new config entry:

config :tailwind,
  version: "3.0.24",
  default: [
    args: ~w(
      --config=tailwind.config.js
      --input=css/app.css
      --output=../priv/static/assets/app.css
    ),
    cd: Path.expand("../assets", __DIR__)
  ]

Commands I ran: mix tailwind.install

This is the output from the command: 11:38:52.064 [debug] Downloading tailwind from https://github.com/tailwindlabs/tailwindcss/releases/download/v3.0.24/tailwindcss-macos-arm64

Then I ran: mix tailwind default

Output: ** (Mix) mix tailwind default exited with 137

Are there any artifacts that I need to delete to ensure tailwind updates properly?

[chrismccord]

You could try invoking the standalone tailwinds cli directly from your _build dir and seeing if it provides more helpful output:

$ cd assets
$ ../_build/ailwindcss-macos-arm64 --config=tailwind.config.js --input=css/app.css --output=../priv/static/assets/app.css 

[JosephShering]

I ran: cd assets

Then: ../_build/tailwind-macos-arm64 --config=tailwind.config.js --input=css/app.css --output=../priv/static/assets/app.css

This was the output: [1] 47934 killed ../_build/tailwind-macos-arm64 --config=tailwind.config.js --input=css/app.css

I can fork and maybe take a look since you don't have an M1

@JosephShering same over here on my M1

I managed to fix the problem temporarily by downloading the latest tailwindcss CLI (as described here) and then replacing the (seemingly corrupted) cli Version at ../_build/tailwind-macos-arm64 with the downloaded version

In my case, dropping the _build folder and running mix tailwind.install again helps

@chrismccord I have found out what is causing this problem: Mac OS seems to be killing the binary after you update the version. This has to do with the signature of binary I think.

Simply deleting the binary inside _build and running mix tailwind.install resolves the problem. I think we should update the install script to first delete the file and then write a new file instead overwriting the current file: https://github.com/phoenixframework/tailwind/blob/b1d487608bc0486995772232c72961042ba15676/lib/tailwind.ex#L220

I can open a PR for this if you agree.

@JosephShering It looks like a typo in your issue title. It reads "exists" instead of "exited". can rename the title of this issue to "mix tailwind default exited with 137".

@chrismccord shall I submit a PR or is there some other (better) solution?

Just wanted to confirm that deleting _build/tailwind-macos-arm64 and running tailwind.install fixed it.

I was able to reproduce the problem by changing the config :tailwind, version: "..." version number and running tailwind.install again (as dvic said). After a second install of a different version mix tailwind default always exits with 137.
