我试着在iMac上安装气流

airflow initdb

我有这个错误

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

我找到了这根线, While airflow initdb, ImportError: cannot import name HiveOperator 不适用于在iMac上安装气流,错误也不完全相同。但我还是试了一下。我改变了配置

# load_examples = True # default set up as True
load_examples = False # change to false to avoid airflow initdb error - But the error still there.

但是我在运行airflow initdb时仍然会得到同样的错误。

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“objects”,会引发上面看到的错误。

我在我的Mac上创建了一个测试Conda环境,并尝试通过PIP安装使用各种版本的dill进行失败的导入。

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
(dill_test)  python

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

DILL版本为0.2A1或更高版本的结果(导入对象时无错误):

(dill_test) pip uninstall dill
Uninstalling dill-0.1a1:
