vagrant up --no-parallel command not working

[chencfgs]

Vagrant failed to initialize at a very early stage:

There was an error loading a Vagrantfile. The file being loaded
and the error message are shown below. This is usually caused by
a syntax error.

Path: C:/Users/chenc/Desktop/ScrapyBook/scrapybook/Vagrantfile
Line number: 4
Message: NameError: uninitialized constant TRUE

force_host_vm = TRUE
                ^^^^

change TRUE to true seems work for me.
