BaseURI decoding problem when running serve

[joanlamrack]

Version

3.0.1

Node and OS info

Node 10.6.0/Ubuntu 18.04 LTS

Steps to reproduce

vue create
cd
npm run serve

What is expected?

the initial vue -cli project should be loaded when accessing localhost:8080 and behaving normally

What is actually happening?

when the localhost:8080 accessed, it seems that the vue app is not injected, resulting in blank html page.

in the terminal, it showed error::

weirdly enough, if you made the project in trash directory, it behaves normally.

already tried install and unistalling vue-cli few times as global

Please provide a reproduction repo.
Also, check if this issues is relevant #1451

[haoqunjiang]

Another guess:
It may be caused by the # in your project path.

[joanlamrack]

you were very right indeed, i removed the # and it works, didnt know it would caused complications
