在 AWS EC2 实例中安装气流包后，我正在尝试启动气流网络服务器它显示权限被拒绝问题，我没有得到它试图创建/修改哪个文件或文件夹来得到这个错误。

我有同样的问题。当我在 sudo 模式下安装整个设置时，它得到了解决。请找到我使用的命令：

sudo apt-get update && sudo apt-get -y upgrade

sudo apt-get install python-pip

sudo -H pip install airflow

sudo airflow initdb

sudo airflow webserver -p 8080

我有同样的问题，现有的答案对我不起作用，因为用户没有 sudo 权限。对我有用的是将 bin 添加到路径中：

export PATH=$PATH:/usr/local/bin

或者在我的情况下：

export PATH=$PATH:~/.local/bin

然后我可以运行：

airflow webserver -p 8080

代替：

.local/bin/airflow webserver -p 8080
