The problem of running the command "composer install"

,

I get this error.

$ -composer install
/home/travis/.travis/functions: line 109: eval: -c: invalid option
eval: usage: eval [arg …]
The command “-composer install” failed and exited with 2 during .
Your build has been stopped.

Can you tell what could be the problem?

The mistake was incredibly simple. Missing space after hyphen -composer install

It is very strange that the final build that creates the assembly is absolutely identical.
