How to install bazelisk

Bazelisk is a bazel wrapper, which provides an easy way to switch between different bazel versions, without uninstalling you local bazel installation. For more information take a look at the Github repository

Linux

The following manual explains how to install bazelisk on a ubuntu host. This should be the same on any other Debian based systems. Some things may differ if you're using a different Linux distribution. In that case please look up your errors and add them to the troubleshooting section.

First Step: Install go

The installation slightly differs between Ubuntu versions. Please take a look here. The first paragraph on Ubuntu 19.04(LTS) should be fine.

Second Step: Install Bazelisk

  • run go get github.com/bazelbuild/bazelisk
  • add the following to your path variable: export PATH=$PATH:$(go env GOPATH)/bin
    • This changes depending on wheter you want to use bazelisk only for your user, or systemwide.
  • you may also want to symlink bazelisk to bazel, but that's not really neccessary and for advanced usage

macOS
