在iMac上安装Apache Airflow-Airflow initdb-ImportError:无法导入名称对象

我试图在iMac上安装airflow

airflow initdb

我犯了这个错误

Traceback (most recent call last):
    File "/Users/admin/anaconda/bin/airflow", line 21, in <module>
      from airflow import configuration
    File "/Users/admin/anaconda/lib/python2.7/site-packages/airflow/__init__.py", line 37, in <module>
      from airflow.models import DAG
    File "/Users/admin/anaconda/lib/python2.7/site-packages/airflow/models.py", line 32, in <module>
      import dill
    File "/Users/admin/anaconda/lib/python2.7/site-packages/dill/__init__.py", line 60, in <module>
      from . import objtypes as types
    File "/Users/admin/anaconda/lib/python2.7/site-packages/dill/objtypes.py", line 16, in <module>
      from dill import objects
    ImportError: cannot import name objects

但是当我运行initdb时仍然会遇到相同的错误。

您可能需要检查系统上安装的dill版本。0.2a1之前的版本（特别是0.1a1版本）不包含“对象”，并且会抛出您在上面看到的错误

我在mac上创建了一个测试conda环境，并通过pip安装尝试了不同版本的dill的失败导入

dill版本0.1a1的结果：

(dill_test) pip install dill==0.1a1
Collecting dill==0.1a1
Installing collected packages: dill
Successfully installed dill-0.1a1

>>> from dill import objects
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
ImportError: cannot import name objects

---

这可能是因为您使用的是anaconda，并且包

dill

与Python版本不同吗？谢谢。这是迪尔发行的版本。在另一台Mac上，我有更新的anaconda，我没有这个错误。数据库工作正常。我将尝试更新anaconda，看看它是否能解决问题，但是当我尝试在一个新的环境（Python3）上进行fresh安装时，我仍然在运行initdb时出错。我会用另一种方式问它。
