该错误是因为在代码的第二行中，使用了未定义的变量`name`，应该将其更正为`__name__`。同时，代码的最后一行`if name == 'main':`也应该更正为`if __name__ == '__main__':`。修改后的代码如下：

if not hasattr(watchdog.events, "EVENT_TYPE_OPENED"):
    watchdog.events.EVENT_TYPE_OPENED = 'created'

app = Flask(__name__)

qa_df = pd.read_excel('qa.xlsx')

def process_text(text):
    text = text.lower().strip()
    text = re.sub(r'[^\w\s]', '', text)
    return text

def match_question(text):
    for i, row in qa_df.iterrows():
        if re.search(row['question'], text):
            return row['answer']
    return None

@app.route('/api/chatbot', methods=['POST'])
def chatbot():
    text = request.json['text']
    processed_text = process_text(text)
    answer = match_question(processed_text)
    if answer:
        return jsonify({'response': answer})
    else:
        return jsonify({'response': 'Sorry'})

if __name__ == '__main__':
    app.run(debug=True)

修改后，应该就可以解决该错误了。
