Issue with react i18next singular and plural, always return plural value
问题
I have some confusion with i18next. When I use the English language, it's completely correct. However, when I change the language to Chinese (zh), it always returns a plural value even when the value is singular.
I've tried upgrading dependencies and changing the configuration, but it still doesn't work.
Here's your provided sample code:
i18n
.use(Backend)
.use(initReactI18next)
.init({
ns: ["common"],
defaultNS: "common",
resources,
fallbackNS: "en",
supportedLngs: ["en", "zh"],
interpolation: {
escapeValue: false
},
react: {
bindI18n: "loaded languageChanged"
},
returnEmptyString: false,
nsSeparator: false
});
export default i18n;
Dependencies version:
i18next 21.3.1
intl-pluralrules 1.3.1
react 17.0.0
react-i18next 11.12.0

这不是一个错误，而是一个特性
不同语言（区域）有不同的适用复数后缀。
您可以只使用允许的后缀或i18n回退到另一个（如果存在的话）命名空间。
阅读 https://www.i18next.com/translation-function/plurals
并使用（由i18next提供，您可以在上一页找到链接） https://jsfiddle.net/6bpxsgd4 来检查您所需语言（区域）支持的后缀。
例如：
- 英语（en）：_one，_other；
- 中文（zh）：_other；
- 俄语（ru）：_one，_few，_many。
所以当您提供翻译键时，需要记住这一点。
当我尝试为“en”和“ru”使用“month_one”和“month_other”时，我也遇到了类似的问题：
这是因为“ru”不支持“_other”后缀。当我只使用“month”和“month_one”键时，问题得以解决。
对于您的情况 - 中文（zh）仅支持“_other”后缀（或者干脆不使用后缀）：
{
"test": "測試",
"month_one": "{{ count }} 月" // 不起作用，因为"zh"没有"_one"后缀
"month_other": "{{ count }} 月s" // 或者"month": "{{ count }} 月s"
}
英文:
It's not a bug, but a feature
Different languages (locales) have different applicable plural suffixes.
You can use only allowed suffixes or i18n fallbacks to another (if existed) namespace.
Read https://www.i18next.com/translation-function/plurals
and use (provided by i18next, you can find the link on previous page) https://jsfiddle.net/6bpxsgd4 to check what suffixes your desired language (locale) supports.
For example:
- English (en): _one, _other;
- Chinese (zh): _other;
- Russian (ru): _one, _few, _many.
So you need to keep it in mind, when you provide translation keys.
I also encountered similar problem when I tried to use "month_one" and "month_other" for "en" and "ru":
All because "ru" don't support "_other" suffix. The problem is solved when I used just "month" and "month_one" keys.
For you case - Chinese (zh) only supports "_other" suffix (or just dont use suffix at all):
{
"test": "測試",
"month_one": "{{ count }} 月" // won't work, because there is no "_one" for "zh"
"month_other": "{{ count }} 月s" // or "month": "{{ count }} 月s"
}
