Answer 1

看起来它按预期工作，你将山雀设置为：
aria-valuenow="25"

您确定包含了正确的bootstrap css和'js'文件吗？

class Demo extends React.Component {
      render() {
        return (
              <div>
                <div className="profile_record">
                  <h5 className="progress-label"><strong>PROFILE COMPLETENESS</strong></h5>
                  <div className="progress">
                    <div className="progress-bar" role="progressbar" style={{width: "25%"}} aria-valuenow="25" aria-valuemin="0" aria-valuemax="100">25%</div>
                  </div>
                </div>
              </div>
            )
           }
         }
         
ReactDOM.render(<Demo />, document.getElementById('root'));

从2018年9月开始，您可以使用Bootstrap ProgressBar，此处的积分为BootStrap ProgressBar

import { ProgressBar } from "react-bootstrap";

<div>
  <ProgressBar variant="success" now={40} />
  <ProgressBar variant="info" now={20} />
  <ProgressBar variant="warning" now={60} />
  <ProgressBar variant="danger" now={80} />
</div>
