How the package develop mode is working is entirely changed. Please look at the [documentation](https://github.com/nim-lang/nimble/#nimble-develop) for reference. > After switching to devel, my first nimble command (nimble test to be precise) > showed me this error : The reason for this is that the structure of the packages cache is changed in order to support the new package develop mode and lock files. I admit that this is inconvenient, but if you don't want to delete the entire directory you can simply delete the `nimbledata.json` file, `pkgs` directory, and the links to binary packages from the `bin` directory.
