When doing using the cr command with 8.1 and v0.11.1:

$ ../drupal.phar cr
 Select cache. [all]:

 Rebuilding cache(s), wait a moment please.

@joshuataylor: Drupal 8.1 requires symfony components 2.8 while 8.0 requires 2.7 we are planning to tag a new version for DC 1.0.0-alpha1 including support for 8.1 once 8.1.0-rc11.

[jmolivas]

We will update DC dependencies once a stable version of Drupal 8.1.x got release

[markdorison]

FYI: Drupal 8.1.0 has now been released.

[jmolivas]

New DC will be released today with support for 8.1.0

[jmolivas]

Drupal Console v1.0.0-alpha1 is release, providing support for 8.1.x and dropping support for 8.0.1

[asauterChicago]

For anyone struggling with how to install the alpha version that works with 8.1, follow the directions on the main page of Drupal Console, but change this line:

php -r "readfile('https://drupalconsole.com/installer');" > drupal.phar

to:

php -r "readfile('https://github.com/hechoendrupal/DrupalConsole/releases/download/1.0.0-alpha1/drupal.phar');" > drupal.phar

Then follow the rest of the directions. Took me a bit to figure how to get and install the alpha version because "drupal self:update" won't work for this.

Anyway, can confirm the Alpha version fixes this error.
