Purpose
Install or update the dasel v3 binary from GitHub Releases into user-space (~/.local/bin on Linux/WSL2/macOS, %LOCALAPPDATA%\Programs\dasel on Windows). The install script handles platform detection, SHA256 verification, and PATH setup.
Install Script
The install script is a PEP 723 Python script at ${CLAUDE_PLUGIN_ROOT}/scripts/install_dasel.py.
Commands
Install or update to latest version:
${CLAUDE_PLUGIN_ROOT}/scripts/install_dasel.py
Force reinstall (even if already at latest version):
${CLAUDE_PLUGIN_ROOT}/scripts/install_dasel.py --force
Preview what would happen without making changes:
${CLAUDE_PLUGIN_ROOT}/scripts/install_dasel.py --dry-run
Install to a custom directory instead of the default:
${CLAUDE_PLUGIN_ROOT}/scripts/install_dasel.py --bin-dir /custom/path
Verify Installation
After install, confirm dasel is available:
dasel --version
Expected output format: dasel version v3.x.x
Supported Platforms
- Linux x86_64 (amd64)
- Linux ARM64 (aarch64)
- Windows x64 (native + WSL2)
WSL2 uses the Linux binary (dasel_linux_amd64), not the Windows .exe. The WSL2 environment is a full Linux subsystem.
Troubleshooting
"command not found" after install
~/.local/bin is not in PATH. Add it:
export PATH="$HOME/.local/bin:$PATH"
Make persistent by adding to ~/.bashrc or ~/.zshrc:
echo 'export PATH="$HOME/.local/bin:$PATH"' >> ~/.bashrc
source ~/.bashrc
Download failures
- Check internet connectivity:
curl -I https://api.github.com
- GitHub API rate limits: unauthenticated requests are limited to 60/hour. Set
GITHUB_TOKEN environment variable for higher limits.
- Retry with
--force after transient failures.
SHA256 mismatch
The install script verifies the downloaded binary against the SHA256 digest from the GitHub API response. A mismatch indicates a corrupted download or tampered binary.
Fix: re-download with --force:
${CLAUDE_PLUGIN_ROOT}/scripts/install_dasel.py --force
Permission denied
Ensure the install directory exists and is writable:
mkdir -p ~/.local/bin
ls -ld ~/.local/bin
The directory should be owned by the current user with write permission.
