Issue: Import metaworld Error
Root cause: Environment Incompatibility

when I try to use metaworld,I get a error.it is:
```
>>> import metaworld
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
  File "/home/fangyu/anaconda3/envs/metaworld/lib/python3.5/site-packages/metaworld/__init__.py", line 20
    env_name: EnvName
            ^
SyntaxError: invalid syntax

```
could you help me?

@csufangyu I think you've installed the metaworld package incorrectly.

You should go ahead and do the installation procedure inside the readme. 

Cheers,
@avnishn 

hi，I do the installation according to the readme.and this is my procedure:
```
(metaworld) fangyu@Robot-DGX-Station:~/robot_learning$ pip install git+https://github.com/rlworkgroup/metaworld.git@master#egg=metaworld
