Autodetection fails

[Mi605]

Autodetection seems to fail, even on your example:

$ translate-cli -t zh "This is a pen."

Translation: '' IS AN INVALID SOURCE LANGUAGE . EXAMPLE: LANGPAIR=EN|IT USING 2 LETTER ISO OR RFC3066 LIKE ZH-CN. ALMOST ALL LANGUAGES SUPPORTED BUT SOME MAY HAVE NO CONTENT

Also explicitly asking for autodetection fails:

$ translate-cli -f autodetect -t zh "This is a pen."
$ translate-cli -f 'autodetect' -t zh "This is a pen."

It comes up with the same result, for any target language. Only entering a valid language identifier for source language explicitly instead works as expected:

$ translate-cli -f en -t zh "This is a pen."

Trying to use a different service provider fails completely:

$ translate-cli -p deepl -f autodetect -t zh "This is a pen."

    'Please check providers list bellow: {!r}'.format(self.available_providers)

Any idea what could cause all this? Maybe the install errors I encountered could cause it?

$ pip install translate
