Rails server can't be started because of the log problem

[tony612]

After my Rails project is compiled, an error is raised when I try to start the server

The lls_logger is a logging gem, lls_logger-ffb74f91993e/lib/lls_logger/file_logger.rb:4 is like:

module LlsLogger
  class FileLogger < ::Logger
    def initialize(tag, log_dir: 'log')
      super(File.join(log_dir, "#{tag}.log"))
    end
  end
end

@tony612 Try adding this line at the top of your config/initializers/logger.rb:

Dir.mkdir('/__enclose_io_memfs__/local/log')

I am guessing that this is due to in part of the compiling process we deleted log and tmp folders, expecting a new one to be created at a temporary location in runtime. Cf. compiler.rb

tmp and log folder issues has been fixed in 0384f89.

Still have other issues. Seems like creation of log files inside log folder failed. It should be redirected to a temporary location. Let me fix it ASAP.
