Cannot apply any Bootstrap style in using React-bootstrap library
问题 I want to use default Bootstrap components in my React application, so I'm using React-bootstrap NPM-package. But I stuck at the very beginning: I cannot use any default component although I'm just copying very simple exmaples from official docs. Every time I use Bootstrap-styled component, I get basic component withouts styles.
