Question

I want to setup a private tangle on my own virtual machine with Ubuntu 18.04, 4GB RAM and 20GB memory. I have follow this instructions: https://docs.iota.org/docs/compass/0.1/how-to-guides/set-up-a-private-tangle. Every command works fine until reach this one: bazel run //docker:layers_calculator. It shows an error as follows:

Starting local Bazel server and connecting to it...

Answer 1

I have solve this issue by using this commands:

Step 3: Set up your environment If you ran the Bazel installer with the --user flag as above, the Bazel executable is installed in your $HOME/bin directory. It’s a good idea to add this directory to your default paths, as follows:

export PATH="$PATH:$HOME/bin"

You can also add this command to your ~/.bashrc or ~/.zshrc file to make it permanent.
