[BUG] illegal hardware instruction, please compile without the AVX2 requirement

@diwu-sf can you see if this repros in version 1.0.69 ?

(base) ➜  Projects claude install 1.0.69

✔  Claude Code successfully installed!

  Version: 1.0.69

  Location: ~/.local/bin/claude


  Next: Run claude --help to get started
(base) ➜  Projects ~/.local/bin/claude --version
[1]    87076 illegal hardware instruction  ~/.local/bin/claude --version

similar problem, is the build machine running with target-cpu=native?

This should be working better in upcoming release 1.0.84 - likely rolling out Monday

@ant-kurt this is still happening with 1.0.84.
For reference the NPM version works fine, even the ripgrep binary from the npm install works fine.

Hmm - can you try running v1.0.84 with env var USE_BUILTIN_RIPGREP=0 to see if that isolates the problem?

oo, same thing happening with me
Apple M1 Pro Sonoma 14.7.6（23H626）

i got this illegal instruction when installing with native

curl -fsSL https://claude.ai/install.sh | bash
Setting up Claude Code...
bash: line 142:  1399 Illegal instruction: 4  "$binary_path" install ${TARGET:+"$TARGET"}

then i went to brew cask, and installment passed but i couldn't boot it after installment... here is the log

brew install --cask claude-code
==> Downloading https://formulae.brew.sh/api/cask.jws.json
==> Caveats
Claude Code's auto-updater installs updates to `~/.local/bin/claude` and
not to Homebrew's location. It is recommended to disable the auto-updater
with either `DISABLE_AUTOUPDATER=1` or
`claude config set -g autoUpdates false` and use
`brew upgrade --cask claude-code`.

Job 1, 'claude' terminated by signal SIGILL (Illegal instruction)

npm version worked fine with me before too.

@ant-kurt version 1.0.86 native still has trouble on that intel macbook without the avx2

Env var USE_BUILTIN_RIPGREP=0 does not help

I have the same issue with native install script - Mac Mini 4,1 - Linux Mint 22.2 Zara
Tried setting USE_BUILTIN_RIPGREP=0, with no impact
npm install succeeds, and claude code works properly

same issue on mac pro m1

illegal hardware instruction claude

Not exactly the same issue as the original post but I am getting Illegal instruction: 4 when I run the claude command after installing via Homebrew. I tried installing via curl and got bash: line 142: 2857 Illegal instruction: 4 "$binary_path" install ${TARGET:+"$TARGET"}. I am on a 2021 Macbook Pro with Apple M1 Max chip and Sonoma 14.6.1.

Update:

Somehow I was running an intel shell on my M1 mac. To fix this I ran chsh -s /bin/zsh. Then I reinstalled homebrew, ensuring it was the ARM version installed in /opt/homebrew. Then I reinstalled Claude and deleted the old Claude at /usr/local/bin/claude. This is not a bug with Claude, I'm just leaving this here in case someone else has a similar issue.

arch -arm64 brew install --cask claude-code

on MacOS M1

first i installed with curl -fsSL https://claude.ai/install.sh | bash and got this error:

Setting up Claude Code...
./install-claude.sh: line 142: 41806 Illegal instruction: 4  "$binary_path" install ${TARGET:+"$TARGET"}

then i successfully installed with arch -arm64 brew install --cask claude-code, but when run claude command, got this error

[1]    62886 illegal hardware instruction  claude

finally, i uninstalled and installed via npm install -g @anthropic-ai/claude-code. now, it worked fine

Still happening! On a circa 2012 Mac Mini

CPU: Intel(R) Core(TM) i5-3210M CPU @ 2.50GHz
AVX flags:
AVX1.0
vinest@Pippin-190 bi

same here on Intel(R) Core(TM)2 Duo CPU P8600 @ 2.40GHz
claude --version
Illegal instruction (core dumped)

@UNIXTCPIP you’re using for moltbot?

Seeing the same, illegal instructions on late 2013 Mac Pro, 2.7 GHz 12-Core Intel Xeon E5. Manifests with both curl install and brew.

to make it clear, npm install works fine the problem is with the native install. please add support for older CPUs.

Have the same issue on MacBook Pro 13-inch M1.

Same on Intel Mac Pro

Verified that this is still happening on a Mac Pro 3,1 running Ubuntu 22.04 LTS.

I can install the NPM version, but I can't install the native version because it fails when it tries to run the downloaded binary, and the VS Code extension also fails.
