locale.Error: unsupported locale setting in Python3.5.2 window7

[yifanshu02]

hi @LoveBootCaptain ,
i saw your project by twitter, and at the same i see this project here.i'm a beginner in python,too. So i try to build this project. And i encounter an error:

Traceback (most recent call last):
  File "C:\Users\Administrator\Desktop\WeatherPi_TFT-master\WeatherPi_TFT.py", line 16, in <module>
    locale.setlocale(locale.LC_ALL, locale.getdefaultlocale())
  File "D:\Python35\lib\locale.py", line 594, in setlocale
    return _setlocale(category, locale)
locale.Error: unsupported locale setting

i dont know where is wrong.However,i annotate return _setlocale(category, locale) in "D:\Python35\lib\locale.py", line 594
and the error is gone
But there is a new error:

Traceback (most recent call last):
  File "C:\Users\Administrator\Desktop\WeatherPi_TFT-master\WeatherPi_TFT.py", line 637, in <module>
    loop()

    obj, end = self.scan_once(s, idx)
json.decoder.JSONDecodeError: Expecting property name enclosed in double quotes: line 3 column 1 (char 59)

i have no idea about it...

PS: i can get defaultlocale by locale.getdefaultlocale():

>>> locale.getdefaultlocale()
('zh_CN', 'cp936')

Do you have a idea?

hi there,

it seems there is an issue with your chinese locale settings. the script and the api require a UTF-8 compatible locale setting.

i guess you are trying it out on your local desktop computer with windows, right?

since i'm not a windows user since years i can`t give you a detailed instruction to set up a new locale in windows... perhaps you can add a new user that have a "en_US.UTF-8"-like locale?

by the way... the api request in the script is configured for a german respond... if you are a beginner, that seems some damn good quests to solve for you. ;) read the api documentation for any details how to configure the request and the respond. the request-url is constructed in the Update.update_json()-function

feel free to contact me, if you need more help.

[LoveBootCaptain]

Oh... and please rename your folder to "WeatherPi_TFT"... don't know when you cloned the repo... i made some fixes with "sys.path[0]" for Folder-PATH in the last commits to solve variable folder names for that application... or just update the project via git or download again ;)

@LoveBootCaptain ，thanks for your reply
Errors were excluded：

#locale.setlocale(locale.LC_ALL, locale.getdefaultlocale())
locale.setlocale(locale.LC_ALL, 'uk')

i find that the X in locale.setlocale(locale.LC_ALL, X) must be 2 byte. 'mai' and 'univ' do not work. i dont konw why

Then:
```
#config_data = open(PATH + 'config.json').read()

        #config = json.loads(config_data)

        #forecast_io_key = config['FORECAST_IO_KEY']

        forecast_io_key = 'f582cd3707f536dda08250505bfeea0c'

it is OK that i give key code to forecast_io_key,directly. it is not OK that give it though json.loads
i m confusing it.Maybe compatibility is poor?

[LoveBootCaptain]

you can use setlocale to overwirte your default locale. but i think (at least in linux) you have to install this locale you want to use. that means when you want to use en_US and UTF-8 it has to be installed.

in locale.setlocale(locale.LC_ALL, locale.getdefaultlocale()) you have to pass in a tuple with language (e.g. en_US) and a encoding (e.g. UTF-8) for locale.getdefaultlocale()

e.g.: locale.setlocale(locale.LC_ALL, ('en_US', 'UTF-8'))

i don't know what happen, if you uncomment this completely... i needed to use it to solve problems with strange characters like german umlauts (ä, ö, ü, ß), which come from the API (like in forecast-summary strings).

long story short: be shure you set the API request to use english as language AND your os should be set up to en_US and UTF-8 too and it should work.

here is an API request you can use (weather is from New York):
https://api.forecast.io/forecast/YOUR_API_KEY/40.7058253,-74.1180847?lang=en&units=si&exclude=flags

you don't have to use API key from the json file. just overwrite the hole request_url-variable with the url above and insert your API key.

please do not share your secret keys ;) you can reset it in the account settings of https://darksky.net/dev/account
thats the reason i used a json file for configuration... my config.json is excluded in my project so i do not commit my secret key here on github by accident ;) and i thought it is a good idea if i want to add more configuartion without changing the script... (like display brightness or intervals for the API-updates).

your first json error looks like you probably missed the double quotes for the key or the value. just replace the xxxx with your API-key but not the " " ;) . it has to look this (no comma at the end -> i have to change that in the example):

{
    "FORECAST_IO_KEY": "xxxxxxxxxxxxxxxxxxxxxxxxx"
}

hope this helps ;) just tried it on a fresh and new installed jessie-raspbian... it runs out of the box on a raspberry pi with latest raspbian image with english locale.

[yifanshu02]

Thanks for your suggestion!

About json error ,i have found the key.Yesterday my json is:

{
    "FORECAST_IO_KEY": "xxxxxxxxxxxxxxxxxxxxxxxxx",
}

now i remove the last ',' .and the code is working......
what a boring ','!
AND i suggest the geographic coordinate values, lang,units,exclude should be added to config.json

[LoveBootCaptain]

More options in config are already done, but not committed and pushed yet. I will update it later today. Great that it works now. That means you fixed the locale issue? If yes, How?

[yifanshu02]

About the setlocale .in the locale.py there is
'uk': 'uk_UA.KOI8-U',

In the project,the code 'locale.setlocale(locale.LC_ALL, 'uk_UA.KOI8-U')' is not working
However, the code 'locale.setlocale(locale.LC_ALL, 'uk')' is working
:(

[LoveBootCaptain]

ah great.

it has to be a tuple in XX locale.setlocale(locale.LC_ALL, XX). means it has to be locale.setlocale(locale.LC_ALL, ('uk_UA', 'KOI8-U')) in your case.

'uk' is returning this correctly. that's why it works ;)

[yifanshu02]

In addition,when i use locale.setlocale(locale.LC_ALL, '') or locale.setlocale(locale.LC_ALL, 'zh')
the UI do not show some character at the position of "week" and "month"

[LoveBootCaptain]

this could be cause the font don't has that special character... feel free to change the font to one which has that. it has to be in .ttf-format. there are some other fonts in the folder which might work. you can also use one of your system fonts. see http://www.pygame.org/docs/ref/font.html for more details or just copy/paste a .ttf file to the /font folder

(i know this problems cause of the german umlauts (ä, ö, ü) too... hate those crazy umlauts like those commas i missed to remove in examples 😂 )

[yifanshu02]

I use the locale.setlocale(locale.LC_ALL, 'uk').everything is OK.
I think when i use locale.setlocale(locale.LC_ALL, 'zh'),the UI should show Chinese.but the .ttf in /font have not Chinese
And locale.setlocale(locale.LC_ALL, ('uk_UA', 'KOI8-U')) do not work.......:(

[LoveBootCaptain]

if you find a font which looks good on the device or a Roboto-Chinese-Font feel free to add it via pull request. the equivalent of Roboto-Font in android and chrome is Noto-Font (https://material.io/guidelines/style/typography.html#typography-typeface), here is a link to google fonts: https://fonts.google.com/specimen/Noto+Sans?selection.family=Noto+Sans.

perhaps the locale issue is related to os? who knows... in mac os and linux it works... on windows not... locale.setlocale(locale.LC_ALL, 'de') is not working on my raspberry 😂 i need the long form for my system-locale

[yifanshu02]

All right,I will try it .
locale.setlocale(locale.LC_ALL, 'de') is working on window7.I will try it on my RPI2 and 2.2'TFT
Now i think accuracy of weather forecast of your code is higher than squix78's code
and accuracy of your code about moon change seem not higher than squix78's code

[LoveBootCaptain]

about the moon issue:

the moon-phase is provided via API (and the Temp-Data too) which might be the difference. squix78 is using another API (wonderground). i use darksky (forecast.io). darksky is providing moonphase in a value which is percentage.
today there is 0.97 provided via darksky for Berlin, Germany. Which means 1% of the moon should be visible. here is a link to a moonphase calender: http://www.kalender-365.eu/mond/aktueller-mondstand.html which tells is 1% is visible too...

my icons are 28 for 31 possible moonphases. i do a little math in moon_icon = int((float(moon_icon) * 100 / 3.57) + 0.25) to map the percentage to 28 icons.

i guess for 1% visible moon it is ok... for squix78 and my code 😂 1% is nearly unvisible.
i can make some more small icons to make it more detailed... but the icons from the source are only 28 😈
