Try，除了：sqlite3.error:没有这样的表：

我的烧瓶应用程序出现了一些问题，这是我直到今天才遇到的问题，我没有改变任何东西，所以它非常混乱

所以它是我的app.py

@app.route('/view.html')
def data():
    try:
        path = 'app/database.db'
        con = sqlite3.connect(path)
        cur = con.cursor()

        con.row_factory = sqlite3.Row
        rows = cur.execute("select * from table").fetchall()
        return render_template('layouts/default.html',
                               content=render_template('pages/view.html',
                                                       rows=rows))

    except sqlite3.OperationalError:
        return render_template('layouts/default.html',
                               content=render_template('pages/view.html'))

其思想是，如果数据库中还没有表，它将捕获错误并返回view.html，其中没有数据，但由于某种原因它不再工作

刚意识到我完全忘了添加错误，我的错误

需要注意的是，该应用程序在localhost上运行良好，它现在只显示错误，而以前从未显示过错误

发生了什么？你有什么错误？@Jacobm001很抱歉，我刚刚添加了它
