Install from Source

This page provides instructions on installing Tendermint from source. To download pre-built binaries, see the Download page.

Install Go

Make sure you have installed Go and set the GOPATH.

Install Tendermint

You should be able to install the latest with a simple

go get github.com/tendermint/tendermint/cmd/tendermint

Run tendermint --help for more.

If the installation failed, a dependency may been updated and become incompatible with the latest Tendermint master branch. We solve this using the glide tool for dependency management.

Fist, install glide:

go get github.com/Masterminds/glide

Now we can fetch the correct versions of each dependency by running:

cd $GOPATH/src/github.com/tendermint/tendermint
glide install
go install ./cmd/tendermint

Note that even though go get originally failed, the repository was still cloned to the correct location in the $GOPATH.

The latest Tendermint Core version is now installed.

Reinstall

If you already have Tendermint installed, and you make updates, simply

cd $GOPATH/src/github.com/tendermint/tendermint
go install ./cmd/tendermint

To upgrade, there are a few options:

set a new $GOPATH and run go get github.com/tendermint/tendermint/cmd/tendermint. This makes a fresh copy of everything for the new version.
run go get -u github.com/tendermint/tendermint/cmd/tendermint, where the -u fetches the latest updates for the repository and its dependencies
fetch and checkout the latest master branch in $GOPATH/src/github.com/tendermint/tendermint, and then run glide install && go install ./cmd/tendermint as above.

Note the first two options should usually work, but may fail. If they do, use glide, as above:

cd $GOPATH/src/github.com/tendermint/tendermint
glide install
go install ./cmd/tendermint

Since the third option just uses glide right away, it should always work.

Troubleshooting

If go get failing bothers you, fetch the code using git:

mkdir -p $GOPATH/src/github.com/tendermint
git clone https://github.com/tendermint/tendermint $GOPATH/src/github.com/tendermint/tendermint
cd $GOPATH/src/github.com/tendermint/tendermint
glide install
go install ./cmd/tendermint

Run

To start a one-node blockchain with a simple in-process application:

tendermint init
tendermint node --proxy_app=dummy

See the App Development guide for more details on building applications, and the Using Tendermint guide for more details about using the tendermint program.
