Download center

Currently, you can download the DFINITY Canister Software Development Kit (SDK) directly from within a terminal shell on your local computer. With this installation option, you can be logged on as any user and no additional software is required.

Install the latest directly from a terminal

To download and install from a terminal shell:

Open a terminal shell on your local computer.

For example, on macOS open the Applications folder, then open Utilities and double-click Terminal.
Download and install the SDK package by running the following curl command:
```
sh -ci "$(curl -fsSL https://sdk.dfinity.org/install.sh)"
```

Install a specific version from a terminal

If you want to install a specific version, for example, to test against a previous version, you can modify the installation command to include a version.

To download and install a specific version from a terminal shell:

Open a terminal shell on your local computer.
Set the DFX_VERSION environment variable to the version of the DFINITY Canister SDK package you want to install as a prefix to curl command.

For example, to install version 0.8.0, you would run the following command:
```
DFX_VERSION=0.8.0 sh -ci "$(curl -fsSL https://sdk.dfinity.org/install.sh)"
```

If you are using the DFX_VERSION environment variable to install a version of the DFINITY Canister SDK not yet publicly available, see this article for an overview of what’s changed.
