(base) ~ $ conda env export -n mypython37 The exported environment list uses yaml format.ġ) Here is the command to export an environment list of a python environment with and without builds and versions of the packages:.The version of the packages could be removed, too.

Edit the exported environment list if some version is missing.

Export environment list without build versions.

A good practice is to update the current working environment with the latest updates before exporting it.

Exported list with version, which are unavailable any more and so it cannot be imported.

Packages’ versions do tend to deprecate, so the old environment may not be possible to replicate because of a missing package version.

Builds’ versions are specific for the OS and they are different for every Operating systems.

All three a valid entries in the list file – only the name of the package, the name of the package with version and the name of the package with version and build version.

There are package names, followed by version and build version.

There are packages, which are only available in Linux platforms and other only under Windows platform!

There are packages, which are not available for all OS platforms.

Here are some caveats (or features), which may stumble the user to build a working conda environment list file: Conda export and import feature is ideal functionality to build a predefined environment from a list in a text file.
