My macbook pro system info:

  • macOS High Sierra
  • Version 10.13.4

And, I'm trying to following the Office Guidings to install ros-kinetic-distro version in my macbook. However, it's all good until come to the initialize-rosdep step:

$ sudo -H rosdep init
$ rosdep update

Here are the problems:

ERROR: cannot download default sources list from: https://raw.githubusercontent.com/ros/rosdistro/master/rosdep/sources.list.d/20-default.list Website may be down.

So I have to go to the website-page find the suggestions like this:

# os-specific listings first
yaml https://raw.githubusercontent.com/ros/rosdistro/master/rosdep/osx-homebrew.yaml osx

# generic
yaml https://raw.githubusercontent.com/ros/rosdistro/master/rosdep/base.yaml
yaml https://raw.githubusercontent.com/ros/rosdistro/master/rosdep/python.yaml
yaml https://raw.githubusercontent.com/ros/rosdistro/master/rosdep/ruby.yaml
gbpdistro https://raw.githubusercontent.com/ros/rosdistro/master/releases/fuerte.yaml fuerte

# newer distributions (Groovy, Hydro, ...) must not be listed anymore, they are being fetched from the rosdistro index.yaml instead

I'm not familiar with yaml, so I can't make it clear what the suggestions real meanings. And next, I have to install yaml, unfortunately, there're comes another pieces of problems!

So I had installed PyYAML which seems located here:

/Library/Frameworks/Python.framework/Versions/3.6/lib/python3.6/site-packages

with file PyYAML-3.12-py3.6.egg-info.

But failed when I export the PATH into my .zhsrc:

export PATH=/Library/Frameworks/Python.framework/Versions/3.6/lib/python3.6/site-packages:$PATH

yaml https://raw.githubusercontent.com/ros/rosdistro/master/rosdep/osx-homebrew.yaml osx zsh: permission denied: yaml

sudo yaml https://raw.githubusercontent.com/ros/rosdistro/master/rosdep/osx-homebrew.yaml osx

Password:

sudo: yaml: command not found

So, What should I do to config the yaml-command in a right way? And, finally is there anyone make is success to install the ROS in MacBook? I really need your help!

  • yaml in a sources list file probably doesn't refer to a "yaml" application, but to the file format in the URL after it. – Stefan L May 08 '18 at 21:09
  • @StefanL Thanks anyway! So, do you have a good idea to config the ***yaml*** command in MacOS (with .bashrc or .zshrc)? As you know I'm confused with that whether it's a right way or not for me to install the ***PyYAML***, and set the command in my system! – frank jorsn May 09 '18 at 07:25
  • I don't even have any "yaml" command installed on my system, don't think it'll contribute to installing ROS? – Stefan L May 09 '18 at 11:30
  • @StefanL So, Do you know the website-page suggestions meanings (https://raw.githubusercontent.com/ros/rosdistro/master/rosdep/sources.list.d/20-default.list) ? – frank jorsn May 10 '18 at 11:01
  • looks like it's a ROS-specific file format, but appears to me to be inspired by Debian's sources.list format: https://wiki.debian.org/SourcesList – Stefan L May 14 '18 at 22:58
  • @StefanL OK，I got it! Thanks a lot anyway. – frank jorsn May 15 '18 at 02:01

There is now an easy way of installing ROS on OSX using conda: conda install ros-noetic-desktop -c robostack. More info on https://medium.com/robostack/cross-platform-conda-packages-for-ros-fa1974fd1de3 and https://github.com/RoboStack/ros-noetic

Here are my notes for Kinetic and High Sierra (partial success only though, ran out of patience): https://gist.github.com/stela/aba2fbd1d4adc8aa922af29c057f7b86

Another guide for Lunar on Sierra: https://gist.github.com/lubiluk/361a018b267ca4e3ce10cdc68b17363d

The official Kinetic on (unspecified release of) OS X: http://wiki.ros.org/kinetic/Installation/OSX/Homebrew/Source

It's probably much easier to use the docker distribution though on a non-Linux OS.

"Suggestions" is irrelevant. What's happening is that it's trying to access a website to pull data from a file and that website is failing a certificate validation process on your machine.

A lot of suggestions hint at updating your certificates, but so far, none of that seems to help me.

From https://github.com/ros/rosdistro/issues/9721: "I got the same error and fixed it by updating and upgrading the system"

Also: "To solve the error I installed 'ca-certificates' package

sudo apt-get install ca-certificates

Then it worked for me"

  • openssl ca-certificates? Or just install the 'ca-certificates package' on my macos? – frank jorsn May 24 '18 at 06:57
  • Thanks @Caleb Kuester & Shobi P P a lot. For the ***rosdep init*** problem, I had solved it with **j7nn7k** answer from: https://stackoverflow.com/questions/40684543/how-to-make-python-use-ca-certificates-from-mac-os-truststore/42107877. Which just help me get through the ***init-step***, although there're a lot of problems after this step to install ros on my macos. Anyway, thanks again! – frank jorsn May 25 '18 at 07:25
