What's Wrong?

I created a new Claude Pro account. When I try to do the native installer I get an error that another installation is in progress. I used the Claude chatbot and the support chat and they suggested doing a lot of force cleans, but I still get same error.

madhu@Madhus-MacBook-Pro ~ % curl -fsSL https://claude.ai/install.sh | bash

✘ Installation failed

Could not install - another process is currently installing Claude. Please try
again in a moment.

What Should Happen?

I would expect the installation to complete and let me authorize to my Claude account.

Same issue here. Seems to be tied to 2.1.0... curl -fsSL https://claude.ai/install.sh | bash -s 2.0.74 --force doesn't solve it

I tried to use -s stable. But that resulted in an installation that says successful but there was no binary actually installed!!!

curl -fsSL https://claude.ai/install.sh | bash -s stable
Setting up Claude Code...

✔ Claude Code successfully installed!

Version: 2.0.67

Location: ~/.local/bin/claude

Next: Run claude --help to get started

⚠ Setup notes:
• installMethod is native, but claude command not found at
/Users/madhu/.local/bin/claude

✅ Installation complete!

Downgrading to 2.0.75 has helped on MacOS

curl -fsSL https://claude.ai/install.sh | bash -s 2.0.75 --force
