Install Julia Packages
This page describes how to install an Julia package in a CoCalc project.
CoCalc already includes hundreds of Julia packages, but you can install even more or update them inside your project.
Your project must have the “Internet access” upgrade in order to download software from a remote repository (i.e. the General Julia package registry to your project. The install command will not work unless you upgrade your project to have internet access.
If a package may have general use but is not already installed in CoCalc, please open a support request to tell us to install it globally for everyone. Please include information about special dependencies or a specific example to test it.

Install a Julia Package from the Command Line
To install custom Julia packages as a normal user, you have to type this in a terminal before starting Julia:
When you do this, you will have to reinstall any needed Julia packages that were installed systemwide, since that’s the way Julia works.

Install a Julia Package in a Jupyter Notebook
No special environment setting is needed. Simply do the following in a code cell in a Jupyter notebook that has the default Julia kernel selected:
import Pkg; Pkg.add("package_name")
and let the install run to completion.
