Installation script hangs at 100% without showing interactive prompt

[curlykay]

What version?

0.44.3

Which command?

curl -fsSL https://moonrepo.dev/install/proto.sh | bash

What happened?

I'm experiencing an issue with the proto installation script:

When running the script:

  curl -fsSL https://moonrepo.dev/install/proto.sh | bash

It hangs at 100% without any further output:

  ######################################################################## 100.0%

At this point, the terminal becomes unresponsive, and no further commands can be executed. The only way to regain control is to forcibly close the terminal session.

After restarting the terminal,the ~/.protobinary is correctly downloaded, but there's no "interactive prompt" as mentioned in the documentation. The script seems unable to complete the installation process or display the expected prompt.

However, I found a workaround: Using the command curl -fsSL https://moonrepo.dev/install/proto.sh | bash -s -- --yes skips the "interactive prompt". With this method, proto is correctly downloaded and the path is properly added to .zshrc. After restarting the terminal, I can use the proto command normally.

Despite the workaround, could you please investigate why the original command doesn't show the interactive prompt as expected? This might confuse users who are following the standard installation instructions.

@curlykay I ran this and it worked:

 curl -fsSL https://moonrepo.dev/install/proto.sh | bash
######################################################################## 100.0%

│ SUCCESS

What shell are you using? I'm assuming zsh based on the snippet above.

Can you try running the install script again with PROTO_LOG=trace PROTO_DEBUG=true set and see what it spits out.

PROTO_DEBUG=true PROTO_LOG=trace bash -c 'curl -fsSL https://moonrepo.dev/install/proto.sh | bash'

[milesj]

I released 0.44.4 with some potential fixes for this. Let me know how it goes.

[curlykay]

I performed a reinstallation and obtained the following log:

~ % PROTO_DEBUG=true PROTO_LOG=trace bash -c 'curl -fsSL https://moonrepo.dev/install/proto.sh | bash'

After that, the only way to regain control of the terminal was still to forcibly close the terminal session.
My shell is Mac Terminal.app + zsh.

Here is the complete view:

Apart from the printed logs, the subsequent progress aligns with my initial feedback.

[milesj]

Hrmm so odd, let me try and recreate it somehow.

[milesj]

Was able to reproduce it with this script!

#!/usr/bin/env bash
set -eo pipefail

echo "> Changing PATH"
echo "  Before=$PATH"

newPath="$PATH"

shimsDir="$HOME/.proto/shims:"
newPath=${newPath/"$shimsDir"/""}

binsDir="$HOME/.proto/bin:"
newPath=${newPath/"$binsDir"/""}

echo ""
echo "  After=$newPath"

export PATH="$newPath"

echo "> Running setup"

echo "" | cargo run -- setup --log trace

It seems like piping is what causes it. If I remove the echo "" | at the end, it works as expected. So I'm assuming the | bash in the original snippet is hanging. Digging further.

[milesj]

I temporarily updated the install.sh script to not prompt, so it should unblock people for now.

[curlykay]

When do I need to try again?

[curlykay]

I've just made the latest attempt and it's already installed without any problems, thanks for debugging!

[milesj]

Fixed in the next version and once this lands: moonrepo/moon#1786

Had to change the command to install though so that stdin works correctly.
