besca installation failure

Hi all,
I'm trying to use 'pip install besca' to install this package in my computer, but there come some Error:

```
AttributeError: module 'configparser' has no attribute 'SafeConfigParser'. Did you mean: 'RawConfigParser'?
[end of output]

note: This error originates from a subprocess, and is likely not a problem with pip.
error: metadata-generation-failed

Encountered error while generating package metadata.
``
See above for output.

note: This is an issue with the package mentioned above, not pip.
```

However, I successfully installed it in other computer previously with the same simple code. I dont know how to solve this.

Start by reproducing `pip install besca` and inspect the package metadata-generation traceback around the `configparser.SafeConfigParser` error. Check the package's Python and dependency compatibility; done means the package installs successfully in the affected environment, but the issue does not name a source file or test.
