Hi Thomas, Not sure about your particular error, but when I installed mine it didn't work due to an outdated Jewel package (apparently Julia came with an older version). Pkg.update() did the trick. Since you get a couple of Jewel-related errors in your output this might be worth trying. In general, the developer of Juno is super helpful and you can approach him with your specific issue on the Julia-LT Gitter <https://gitter.im/one-more-minute/Julia-LT>.
Best of luck!
