Mambaforge – Package Management
\n<\/h1>\n
\n

<\/p>\n

\n

One of the biggest features of Mambaforge is the ability to search and install packages from either a central or an exteral repository. Additionally, package management in Mambaforge is specifically designed to integrate with isolated environments. This page goes over the basics of searching and installing packages with the mamba<\/span> command.<\/p>\n

We also have anaconda3<\/span> available as a module, but we have deliberately chosen Mambaforge for use within our documentation due to the ability to be a drop-in replacement for Anaconda and for the major improvements listed on the mamba Github page<\/a>, particularly the parallel downloads and faster dependency solving.<\/p>\n

More information on conda\/mamba package management can be found on the Conda documentation page<\/a>. While the main command on that page uses the conda<\/span> command, you can replace it with mamba<\/span> and expect the same results.<\/p>\n

Prerequisites<\/h2>\n

In order to install\u00a0mamba<\/span> packages, you must first load the mambaforge<\/span> module and activate a conda environment. Read our Mambaforge – Environments<\/a> documentation page to learn how to do that.<\/p>\n

Note: If a user-created conda environment is not activated, the base conda environment located at \/packages\/mambaforge\/[latest_date]<\/span> will be used instead. This directory is not writable by regular users, so package installation will fail.<\/em><\/p>\n

Searching for Packages<\/h2>\n

To see if a certain package is available, use the\u00a0mamba<\/span> search command:<\/p>\n

mamba search [package_name]<\/code><\/pre>\n
For example, to search for the term ninja<\/span>, a\u00a0mamba<\/span> search command would look like:<\/p>\n
mamba search ninja<\/code><\/pre>\n
Installing Packages<\/h2>\n
To install a specific package, use the mamba install<\/span> command:<\/p>\n
mamba install [package_name] [(optional) more_packages]<\/code><\/pre>\n
For example, to install the ninja<\/span> package, a mamba install<\/span> command would look like:<\/p>\n
mamba install ninja<\/code><\/pre>\n
You can also specify a specific version of a package to install:<\/p>\n
mamba install ninja=1.8.2<\/code><\/pre>\n
Additionally, you can also install multiple packages at once:<\/p>\n
mamba install ninja=1.8.2 pandas<\/code><\/pre>\n
Software Channels<\/h2>\n
Channels<\/em> in\u00a0mamba<\/span> are the repositories that a given package is downloaded from.\u00a0mamba<\/span>has some channels configured by default, which you can see with the conda config<\/span> command:<\/p>\n
$ conda config --show channels\r\nchannels:\r\n  - defaults<\/code><\/pre>\n
*Note: The\u00a0conda config<\/span> command is not provided by mamba<\/span>, so the conda<\/span> command must be used. However, the mambaforge<\/span> module provides the conda<\/span> command, so no additional modules need to be loaded.<\/p>\n
To install software from a channel not listed above, you can use the -c<\/span> flag when using the mamba install<\/span> command. For example, to install the zstd<\/span> package, use the following command:<\/p>\n
mamba install -c conda-forge zstd<\/code><\/pre>\n
Updating Packages<\/h2>\n
To update a package, use the mamba update<\/span> command:<\/p>\n
mamba update [package_name] [(optional) more_packages]<\/code><\/pre>\n
For example, to update the\u00a0ninja<\/span> package, a\u00a0mamba update<\/span> command would look like:<\/p>\n
mamba update ninja<\/code><\/pre>\n
You can also update multiple packages at once:<\/p>\n
mamba update ninja pandas<\/code><\/pre>\n
Removing Packages<\/h2>\n
To remove a specific package, use the\u00a0mamba remove<\/span> command:<\/p>\n
mamba remove [package_name] [(optional) more_packages]<\/code><\/pre>\n
Note: This will uninstall the specifed packages\u00a0in the currently active environment<\/strong>.<\/em><\/p>\n
For example, to remove the ninja package, a\u00a0mamba remove<\/span> command would look like:<\/p>\n
mamba remove ninja<\/code><\/pre>\n
You can also remove multiple packages at once<\/p>\n
mamba remove ninja pandas<\/code><\/pre>\n
You can also remove a package from a specific conda environment:<\/p>\n
mamba remove -n demo_environment ninja pandas<\/code><\/pre>\n<\/div>\n<\/div>\n","protected":false},"excerpt":{"rendered":"
