How to install new packages locally?​

Via Command Palette​

Open your notebook and paste the GitHub link to a repo* in the command palette located on the top bar.

warning

* It must contain a PacletInfo.wl file in the root directory of the repository.

Via LPM​

Create a new cell and insert:

PacletRepositories[{
    Github -> "https://github.com/KirillBelovTest/HTTPHandler"
}, "Directory" -> NotebookDirectory[]]

<<KirillBelov`HTTPHandler`

This will create a local folder named wl_packages, where installed packages will be stored.

Global Installation (Classic)​

Via Paclets​

If the package is hosted on the Wolfram repository, then you can simply run:

PacletInstall["Username/Paclet"]

<<PacletContextName`

Or from a local paclet file:

PacletInstall["path_to_it.paclet"]

<<PacletContextName`
