Resolve from the CLI

Use the one-shot command when conda-presto is installed locally:

conda presto -c conda-forge -p linux-64 python=3.13 numpy
conda presto -f environment.yml -p linux-64 -p osx-arm64 \
  --format rattler-lock-v6 > pixi.lock

The default output is native JSON with a result or error for each platform. Exporter output requires successful solves for every selected platform. The command selects packages without creating or changing a prefix.

To convert a covered lockfile without solving:

conda presto -f pixi.lock -p linux-64 --format conda-lock-v1 > conda-lock.yml

CLI conversion uses the parser’s normal package-record materialization. Use the HTTP Transcode lockfiles without solving operation when package archives must not be fetched.

See CLI reference for flags and exit codes and Output formats for format limitations.
