Question

我目前正在尝试设置一个名为Flower的Python监视工具，以检查是否已成功处理任务。当前，这是我的设置，如下所示：

ubuntu 18.04.2 LTS（GNU / Linux 4.15.0-1044-aws x86_64）
python 3.6.7
芹菜4.3.0
花0.9.3
redis 5.0.5（芹菜经纪人）

当我通过命令行开始开花时

flower -A celery_app --broker='redis://:PASSWORD@redis-endpoint:6379/2' --broker_api='redis://:PASSWORD@redis-endpoint:6379/2'

我收到以下错误： dbm.error: db type is dbm.gnu, but the module is not available

完整错误消息：

我也尝试安装sudo apt-get python3-gdbm，但对我的问题没有帮助。

Answer 1

以防其他人遇到此错误。这是pyenv的问题。即使之后

sudo apt-get install python3-gdbm

该库将安装在系统中，但不会安装在 pyenv 中。所以这里描述的解决方案：

GDBM doesn't work with Python 3.6 and anaconda

pyenv 的步骤相同。

启动鲜花时，我得到以下信息：“ dbm.error：db类型为dbm.gnu，但是模块不可用”
