Can't install

[sanguino]

Hi,

I'm trying to install your api. I had some problems to install bluepy, but now I solved it, I get this error I don't know how to resolve:

pip3 install ./xiaomi-flower-care-api/
Processing ./xiaomi-flower-care-api
    Complete output from command python setup.py egg_info:
    Traceback (most recent call last):
      File "<string>", line 1, in <module>
      File "/tmp/pip-89uw8bo2-build/setup.py", line 13, in <module>
        long_description=readme(),
      File "/tmp/pip-89uw8bo2-build/setup.py", line 7, in readme
        return readme_file.read()
      File "/usr/lib/python3.5/encodings/ascii.py", line 26, in decode
        return codecs.ascii_decode(input, self.errors)[0]
    UnicodeDecodeError: 'ascii' codec can't decode byte 0xe2 in position 830: ordinal not in range(128)

    ----------------------------------------
Command "python setup.py egg_info" failed with error code 1 in /tmp/pip-89uw8bo2-build/

Can you help me? I don't know a lot of python, so maybe it's trivial, sorry if I asking something too simple.

Thanks!

I fixed it adding encoding='utf8' to setup.py:

def readme():
    with open('README.md', encoding='utf8') as readme_file:
        return readme_file.read()

But now I have a problem executing read.py:

~/xiaomi-flower-care-api/example $ sudo python3 read.py
Getting data from device..

Traceback (most recent call last):

I get the exact same error.

I have also encountered the same error with Python 3.5.3 @vrachieru Could you please write which Python version did you use?

[frankfnord]

same error here.
python3 --version: Python 3.7.3

[sanguino]

Me too, Python 3.7.3

This is not a python issue but a shell issue.

If it happens when using SSH, this is a fault on the SSH client, not the RPi. For example using an Ubuntu machine as the SSH client will cause this problem.
To fix this SSH problem, edit the file /etc/ssh/ssh_config on the SSH client (not the RPi) and remove the line
SendEnv LANG LC_*

I had this issue when accessing my raspberry through ssh, removing the SendEnv line solved the issue and I could install xiaomi-flower-care-api properly

did you ever resolved this ?

With Python3 bluepy may need an additional libraries: libglib2.0-dev based on bluepy

sudo apt-get install python3-pip libglib2.0-dev
sudo pip3 install bluepy
