 The way to work around this before the cache expires is to use the GOPRIVATE environment variable to instruct go get to fetch this module directly, bypassing the cache.
 
 From <https://golang.org/cmd/go/>:

+Comma-separated list of glob patterns (in the syntax of Go's path.Match) of module path prefixes that should always be fetched directly or that should not be compared against the checksum database.

 The workaround is:
 
 ```bash
-$ GOPRIVATE=github.com/depp/bytesize go get github.com/depp/bytesize@v1.1.0
+GOPRIVATE=github.com/depp/bytesize go get github.com/depp/bytesize@v1.1.0
 ```
 
 Note that if you are already using GOPRIVATE, you will want to add modules rather than overriding the value completely.
