How to upgrade bazel?

Question

I built bazel-0.4.0 successfully.
Then I tried upgrading it to the latest version bazel-0.5.1 using

$ ./compile.sh compile ../bazel-0.4.0/output/bazel.exe

It's giving me an error, bazel-0.5.0, bazel-0.4.5 gave me same error

ERROR LOG:

$ ./compile.sh compile ../bazel-0.4.0/output/bazel.exe

Answer 1

• To install latest bazel: just run "brew upgrade bazel"

• Problem I had: I wanted 0.5.4 version of bazel for tensorflow 0.8.

• Failed attempt to install specific version: brew install bazel@0.5.1

• Final approach that worked to setup specific version of bazel:

  1. Download bazel-0.5.4-without-jdk-installer-darwin-x86_64.sh from https://github.com/bazelbuild/bazel/releases location
  2. chmod +x ./bazel-0.5.4-without-jdk-installer-darwin-x86_64.sh
  3. ./bazel-0.5.4-without-jdk-installer-darwin-x86_64.sh

That's it!! check bazel version in your terminal. It should give 0.5.4

This approach works for any version of bazel that you want to install..brew way to install specific version didnt work for me. Hope this saves you from wasting hours trying alternative ways to set this up!

In addition to what mhlopko wrote, you generally don't need to build bazel yourself. Feel free to download the binary installer and just use that.

Answer 3

If you already have bazel installed, you can upgrade by running bazel build //src:bazel on a fresh clone of the git repository. Or just download distribution archive and run ./compile. Details: https://bazel.build/versions/master/docs/install-compile-source.html.

Now I'm not sure you can build bazel 0.5.0 with bazel 0.4.0, there were some incompatible changes around 0.4.3. We test building bazel from scratch, and building bazel with last released bazel, but not building bazel with old releases. That will be supported only after we reach 1.0.0.
