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
