, когда я запускаю эту команду curl -vd '{"NickName":"Marry","Password":"pwd"}' -H "Content-type: application/json" http://127.0.0.1:3000/signin, я напечатал No metadata found. There is more than once class-validator version installed probably. You need to flatten your dependencies. на стороне сервера, и validate не работал правильно. Прежде всего, я npm install некоторые зависимости:
npm install --save routing-controllers
npm install --save class-transformer
npm install --save class-validator
Может ли кто-нибудь помочь? Как я могу это исправить? Спасибо!
