Hello faithful readers! If you have tried to follow along in the book, you are asked to start up the dev environment via dx/build and are probably getting some issue like

realpath: /Users/davec/Downloads/code/dev-environment/dx/../../dcsidekiq/Book/code/: No such file or directory

I have a fix coming, but to work around this, you’ll need to comment out some lines of code, as in this gist: dx_build.sh · GitHub

What happened was that I had stuff in that script to sync all the code from where I write the book into the Subversion repo where Prag Prog manages the book’s source and sample code. Since you, the reader, don’t have that, it all breaks. My apologies. Please let me know if this works for you!

Dave
