每当我尝试className='fa-spin'在React中使用FontAwesome微调器图标（带有）时，都会出现以下错误：

Uncaught DOMException: Failed to execute 'removeChild' on 'Node': The node to be removed is not a child of this node.

编辑： 问题已经出现了好几次了，并且代码本身真的没有什么特别的。我一直使用微调器作为加载图标，并且每当用内容替换微调器时都会发生错误。例：

return (
  <div>
    {this.state.loading === true ? <i className="fa-spin fas fa-sync"></i> : (
      this.state.recipes.length === 0 ? (
        <div className='text-center'>
          <h2>There doesn't seem to be anything here...</h2><br />
          <h2 style={buttonStyle}>Get started by </h2><button style={buttonStyle} className='btn btn-md btn-success' onClick={(e) => this.props.setView(e, 'browserecipes')}>browsing existing recipes</button><h2 style={buttonStyle}> or </h2><button style={buttonStyle} className='btn btn-success btn-md' onClick={(e) => this.props.setView(e, 'addrecipe')}>adding a recipe.</button>
        </div>
      ) : (
      <div>
          <h1 className='text-center title'>My Recipe Cloud</h1>
          <RecipeContainer
            recipes={this.state.recipes}
            user={this.state.user}
            tags={this.props.tags}
            setView={this.props.setView}
            changeUser={this.changeUser}
          />
        </div>
      )
    )}
  </div>
