Stellar's utility ("Stellar_Core_Commander") is a tool used to deterministically create snapshots of the SQL DB by running a set of stellar operations. Its written in ruby. To run it, you need to install the relevant Gem file and run:
scc -r <a commands file>
however, its throwing an exception:
Traceback (most recent call last): 4: from /var/lib/postgresql/.rbenv/versions/2.5.0/bin/scc:23:in `<main>' 3: from /var/lib/postgresql/.rbenv/versions/2.5.0/bin/scc:23:in `load' 2: from /var/lib/postgresql/.rbenv/versions/2.5.0/lib/ruby/gems/2.5.0/gems/stellar_core_commander-0.0.12/bin/scc:135:in `<top (required)>' 1: from /var/lib/postgresql/.rbenv/versions/2.5.0/lib/ruby/gems/2.5.0/gems/stellar_core_commander-0.0.12/bin/scc:71:in `run' /var/lib/postgresql/.rbenv/versions/2.5.0/lib/ruby/gems/2.5.0/gems/stellar_core_commander-0.0.12/bin/scc:110:in `make_commander': undefined method `mktmpdir' for Dir:Class (NoMethodError) Did you mean? mkdir
how do I fix this?
