Global options applicable to every lerna sub-command
How many threads to use when Lerna parallelizes the tasks (defaults to count of logical CPU cores)
$ lerna publish --concurrency 1
What level of logs to report. On failure, all logs are written to lerna-debug.log in the current working directory.
Any logs of a higher level than the setting are shown. The default is "info".
Set a max buffer length for each underlying process call. Useful for example
when someone wants to import a repo with a larger amount of commits while
lerna import. In that case the built-in buffer length might not
Disable progress bars. This is always the case in a CI environment.
By default, all tasks execute on packages in topologically sorted order as to respect the dependency relationships of the packages in question. Cycles are broken on a best-effort basis in a way not guaranteed to be consistent across Lerna invocations.
Topological sorting can cause concurrency bottlenecks if there are a small number of packages with many dependents or if some packages take a disproportionately long time to execute. The
--no-sort option disables sorting, instead executing tasks in an arbitrary order with maximum concurrency.
This option can also help if you run multiple "watch" commands. Since
lerna run will execute commands in topologically sorted order, it can end up waiting for a command before moving on. This will block execution when you run "watch" commands, since they typically never end. An example of a "watch" command is running
babel with the
--watch CLI flag.
Fail immediately if a cycle is found (in
