如何在colab中安装bazel？

Question

I want to use bazel builder for some project in colab. But !bazel gives me /bin/bash: bazel: command not found . I tried to install it with

BAZEL_VERSION = '0.20.0'

!wget https://github.com/bazelbuild/bazel/releases/download/{BAZEL_VERSION}/bazel-{BAZEL_VERSION}-installer-linux-x86_64.sh

!chmod +x bazel-{BAZEL_VERSION}-installer-linux-x86_64.sh

# !export PATH="$PATH:$HOME/bin:/root/bin"

But it didn't help. How should I install it?

Answer 1

Use these commands:

!apt install apt-transport-https curl gnupg
!curl -fsSL https://bazel.build/bazel-release.pub.gpg | gpg --dearmor > bazel.gpg
!mv bazel.gpg /etc/apt/trusted.gpg.d/
!echo "deb [arch=amd64] https://storage.googleapis.com/bazel-apt stable jdk1.8" | sudo tee /etc/apt/sources.list.d/bazel.list
!apt update && apt install bazel

Answer 2

The simplest way:

!npm install -g @bazel/bazelisk

npm is already installed by default in Colab. I just tested the above code and it works fine. More info: https://github.com/bazelbuild/bazelisk
