我在线购买了 Gatsby JS 网站的模板，当我尝试使用它时，它起作用了，但随后就停止了。我尝试在新目录中打开该项目，但失败了。
目前我无法运行npm install该项目，也不知道如何解决该问题。
错误消息是：

from sqlalchemy import create_engine
from sqlalchemy.orm import scoped_session, sessionmaker
在其中我创建了一个基本的登录页面和一个注册页面，当我尝试使用 html 代码时：
<form action="/login" method="post">
<input autocomplete="off" autofocus name="username" placeholder="Username" type="text">
<input class="form-control" name="password" placeholder="Password" type="password">
<button class="btn btn-primary" type="submit">Log In</button>
<li style="list-style-type:none;"><a href="/register">Register</a></li>
</form>
在这个Python Flask代码上：
# This is the log in page
@app.route("/login", methods=["GET", "POST"])
def login():
"""Log user in"""
# Forget any user_id
session.clear()
# User reached route via POST (as by submitting a form via POST)
if request.method == "POST":
# Ensure username was submitted …
