我正在尝试在Heroku上部署我的应用程序,但它在/ [GET]上给出内部服务器错误(带有异常)并引发TemplateNotFound,但它在本地主机上成功运行。在运行heroku日志--tails后,我得到了以下问题:

未添加env目录结构,因为它太大了
我的credit.py文件太大,无法共享,因此可以在https://github.com/Shrikant991/Credit-Management-System-in-Flask/blob/master/Credit.py
上查看有什么建议吗?
答案 0 :(得分:0)
根据您的git repo和目录结构,很可能是由于文件夹templates
t区分大小写而引起的。
尝试为此编辑代码。
app = Flask(__name__, template_folder='Templates')
或将您的Templates
文件夹重命名为templates
答案 1 :(得分:0)
“模板”的字母“ t”必须大写。 'DIRS':[os.path.join(BASE_DIR,'Templates')],
