使用Flask访问Python3.6上文件夹的权限被拒绝

编辑：完全忽略此问题。这是一个文件系统问题

每当我试图打开

posts

文件夹时，我都会收到一个错误：

Traceback (most recent call last):

    with open(str(find_recent_post_name())) as post:
PermissionError: [Errno 13] Permission denied: 'posts/'

My main.py文件：

from flask import Flask
from flask import render_template

app = Flask(__name__)

def find_recent_post_name():
    import glob
    posts = glob.glob("posts/")
    return posts[len(posts) - 1]

def find_recent_post():
    with open(str(find_recent_post_name())) as post:
        newest_post = post.readlines()
    return newest_post


@app.route("/")
def index():
    return render_template("index.html", newest_post=find_recent_post())

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

我的Python版本是v3.6.1和v1.12.0

编辑：调试代码和使用PowerShell似乎很有效。

这不是flask的问题。您可以更改文件夹

/posts/

上的权限，也可以作为具有

读取权限的用户运行flask

$ chmod 755 <folder names>

以管理员身份运行或以已具有访问权限的用户身份运行flask。请注意，您应该在部署时添加相同的设置。因此
uwsgi
或
gunicron
的工作人员，或者无论您如何在部署时运行应用程序，都应该使用相同的凭据运行

请注意，您的
用户
应同时具有
读取
或
4
访问权限以读取文件内容，并具有
执行
或
1
访问权限以能够将
cd
放入其中

$ sudo python main.py
