Conda¶

Conda cross-language package and environment manager.

Reads go through conda’s --json mode: installed packages come from conda list --json and search from conda search "*query*" --json. conda has no dedicated outdated command, so the upgrade the solver would perform is simulated with conda update --all --dry-run --json and its UNLINK (current) and LINK (candidate) sets are diffed by name: a name in both is an in-place upgrade, while a LINK-only entry is a freshly pulled dependency and is not reported.

Note

Every operation targets conda’s currently active environment, which is base when none is activated. mpm neither activates nor switches environments: it inspects and mutates whatever environment conda resolves from the inherited CONDA_PREFIX / CONDA_DEFAULT_ENV, exactly as a bare conda call in the same shell would. Per-environment targeting is not supported yet.

Note

The >=4.6.0 floor is the release where update --dry-run --json settled on an actions mapping whose LINK / UNLINK values are package dicts, the shape the outdated diff parses. Much older conda wrapped actions in a list and emitted bare channel::name-version-build strings instead.

Ecosystem¶

Accepted purl types: pkg:conda

Usage¶

$ mpm --conda installed
$ mpm --conda search "query"
$ mpm --conda upgrade --all
$ mpm install pkg:conda/hello
$ mpm --dry-run --conda upgrade --all

Every example above accepts --dry-run, which simulates the underlying manager calls without touching the system: the safe way to watch what mpm would do before trusting it.

Deselect the manager for a single run with --no-conda, disable it from your configuration, or tune its invocation attributes with per-manager overrides.

Command line¶

CLI names, in lookup order: conda

The version is probed by running:

$ conda --version
conda 24.5.0

and extracted with:

r"conda\s+(?P<version>\S+)"

Privilege escalation¶

mpm runs this manager as the current user and never prepends sudo by default. Flip the policy for its privileged operations with --sudo or the per-manager sudo override.

See privilege escalation for the full policy.

Cooldown¶

State of Conda’s release-age gating, from the cooldown support table:

Status: 🚧 Proposed
Mechanism: --exclude-newer / exclude_newer (open issue + PR)
Reference: conda/conda#15759

With --cooldown set, mpm skips this manager’s install and upgrade operations rather than run them unguarded (fail-closed); --allow-unsupported-managers opts back in.

Reference traces¶

Raw native outputs captured in the manager source: the reference mpm’s parsers were written against. If you know Conda well and a transcript below looks wrong, or a newer release changed its output format, report it.
