问题描述
我目前正在尝试设置一个名为 Flower 的 Python 监控工具,以检查任务是否正在成功处理.目前这是我的设置如下:
I am currently trying to setup a Python monitoring tool, called Flower, to check whether tasks are being successfully processed. Currently this is my setup is as follows:
- 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(芹菜代理)
当我通过命令行启动花时
When I start flower via the command line
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 是 dbm.gnu,但是模块不可用

我也尝试安装 sudo apt-get python3-gdbm
但它对我的问题没有帮助.
I also tried installing sudo apt-get python3-gdbm
but it did not help with my problem.
推荐答案
以防其他人遇到此错误.这是pyenv的问题.即使之后
In case someone else face this error. It is problem with pyenv. Even after
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:
the library will be installed in the system, but not in the pyenv. So the solution described here:
GDBM 不适用于 Python 3.6 和 anaconda
pyenv 的步骤相同.
The steps will be the same for pyenv.
