Docker构建失败，airflow 1.10.0和Python2.7没有名为pip._vendor的模块

Question

我有一个python 2.7的docker图像。我试图在映像中安装airflow，但在安装airflow依赖项的pip过程中，我遇到了以下问题。

Dockerfile:-

FROM python:2.7-slim
...
...
# Install Airflow and Celery
COPY pip_airflow.txt /pip_airflow.txt
RUN pip install --no-cache-dir -r /pip_airflow.txt

下面是我的pip_airflow.txt文件。

apache-airflow[all]==1.10.0
celery[redis]>=4.2.1,<4.3.0
flower>=0.7.3,<1.0
kombu>=4.2.0,<5.0

日志：-当从dockerfile执行airflow的pip安装时出现故障。

Collecting pendulum==1.4.4 (from apache-airflow[all]==1.10.0->-r /pip_airflow.txt (line 1))

更新pip，例如pip install pip===19.0.2。在我的例子中，它起作用了。
