can't install by pip

[wwqgtxx]

I had try on the raspbain(RaspberryPI's Linux)

root@raspberrypi:/ST# pip3.6 install git+https://github.com/MongoEngine/flask-mongoengine.git
Collecting git+https://github.com/MongoEngine/flask-mongoengine.git

But it's work fine in a standard ubuntu server 16.04.

Thanks for reporting.

Can you please open your Python interpreter on both platforms, execute

locale.getpreferredencoding(False)

and provide the results?

[wwqgtxx]

on my windows 10

import locale
locale.getpreferredencoding(False)
'cp936'

Another thing you could try.

On each platform, clone the repository, cd into the clone and try to install "by hand" using

python setup.py install

It should fail with the same error.

Then modify setup.py like this:

  import os
+ import io

[...]

  # Load index.rst as long_description
  doc_path = os.path.join(os.path.dirname(__file__), "docs", "index.rst")
- long_description = open(doc_path).read()
+ long_description = io.open(doc_path, encoding='utf-8').read()

And tell us how it went.

Thanks.

Great. Then the procedure I provided might work.

[wwqgtxx]

the diff with

- long_description = open(doc_path).read()
+ long_description = io.open(doc_path, encoding='utf-8').read()

can work fine now.Thanks

You mean you installed successfully on all platforms using this fix?

If so, then we shall release a new version with this fix.

[wwqgtxx]

Yes,I had test on all platforms that I used, and it installed successfully.
