【解决方案1】：

将mx-auto 类添加到form。

如果您不使用此代码：

<ul class="navbar-nav me-auto mb-2 mb-lg-0">
  <li class="nav-item">
  </li>
</ul>

然后移除它，因为你会看到它正在影响search input的位置。

您的 link 和 script 标签位置不正确，因此我对其进行了一些调整。

在表单上使用mx-auto 并从navbar-nav 中删除me-auto...

<nav class="navbar navbar-expand-lg navbar-light bg-light">
    <div class="container-fluid">
        <a class="navbar-brand" href="#">Jain Medicos</a>
        <button class="navbar-toggler" type="button" data-bs-toggle="collapse" data-bs-target="#navbarSupportedContent" aria-controls="navbarSupportedContent" aria-expanded="false" aria-label="Toggle navigation">
            <span class="navbar-toggler-icon"></span>
        </button>
        <div class="collapse navbar-collapse" id="navbarSupportedContent">
            <ul class="navbar-nav mb-2 mb-lg-0">
                <li class="nav-item">
                </li>
            </ul>
            <form class="d-flex mx-auto">
                <input class="form-control me-2" type="search" placeholder="Search" aria-label="Search" size="90">
                <button class="btn btn-outline-success" type="submit">Search</button>
            </form>
        </div>
    </div>
</nav>
