我想做一个简单的古腾堡积木<InspectorControls>, 但无论我使用哪个组件，我都会得到一个React错误。

const { __ } = wp.i18n;
const {
    registerBlockType,
    RichText,
    AlignmentToolbar,
    BlockControls,
    InspectorControls,
    TextControl
} = wp.blocks;

registerBlockType( \'gutenberg-examples/example-04-controls-esnext\', {
    title: __( \'Example: Controls (esnext)\' ),
    icon: \'universal-access-alt\',
    category: \'layout\',
    attributes: {
        content: {
            type: \'array\',
            selector: \'p\',
        },
    },
    edit: props => {
        const {
            attributes: {
                content,
                alignment,
                text
            },
            focus,
            className,
            setFocus
        } = props;

        const onChangeContent = newContent => {
            props.setAttributes( { content: newContent } );
        };

        const onChangeAlignment = newAlignment => {
            props.setAttributes( { alignment: newAlignment } );
        };

        const onChangeText = newText => {
            props.setAttributes( { text: newText } );
        };

        return (
            <div>
                {
                    !! focus && (
                        <InspectorControls>
                            <AlignmentToolbar
                                value={ alignment }
                                onChange={ onChangeAlignment }
                            />
                            <TextControl
                                label=\'Additional CSS Class\'
                                value={ text }
                                onChange={ onChangeText }
                            />
                        </InspectorControls>
                    )
                }
                <RichText
                    className={ className }
                    style={ { textAlign: alignment } }
                    onChange={ onChangeContent }
                    value={ content }
                    focus={ focus }
                    onFocus={ setFocus }
                    />
            </div>
        );
    },
    save: props => {
        // ignore for now
    }
} );
