无法使用pip安装docker-compose，“ImportError：没有名为dockerpycreds的模块”

Question

我尝试使用pip安装docker-compose但我收到此错误：

$ docker-compose
  Traceback (most recent call last):
    File "/usr/local/bin/docker-compose", line 7, in <module>
      from compose.cli.main import main
    File "/usr/local/lib/python2.7/dist-packages/compose/cli/main.py", 
      line 17, in <module>
      from . import errors
    File "/usr/local/lib/python2.7/dist-
      packages/compose/cli/errors.py", line 11, in <module>
      from docker.errors import APIError
    File "/usr/local/lib/python2.7/dist-packages/docker/__init__.py", 
      line 2, in <module>
      from .api import APIClient
    File "/usr/local/lib/python2.7/dist-
      packages/docker/api/__init__.py", line 2, in <module>
      from .client import APIClient
    File "/usr/local/lib/python2.7/dist-
      packages/docker/api/client.py", line 11, in <module>
      from .build import BuildApiMixin
    File "/usr/local/lib/python2.7/dist-packages/docker/api/build.py", 
      line 6, in <module>
      from .. import auth
    File "/usr/local/lib/python2.7/dist-packages/docker/auth.py", line 
      6, in <module>
    import dockerpycreds ImportError: No module named dockerpycreds

更新1：安装docker_pycreds之后，如答案所述，它导致了另一个错误：

Traceback (most recent call last):
  File "/usr/local/bin/docker-compose", line 7, in <module>
    from compose.cli.main import main
  File "/usr/local/lib/python2.7/dist-packages/compose/cli/main.py", 
    line 17, in <module>
    from . import errors
  File "/usr/local/lib/python2.7/dist-packages/compose/cli/errors.py", 
    line 11, in <module>

    in <module>
    from .transport import SSLAdapter
  File "/usr/local/lib/python2.7/dist-
    packages/docker/transport/__init__.py", line 3, in <module>
    from .ssladapter import SSLAdapter
  File "/usr/local/lib/python2.7/dist-
    packages/docker/transport/ssladapter.py", line 22, in <module>
    urllib3.connection.match_hostname = match_hostname
  AttributeError: 'module' object has no attribute 'connection'

更新2：在pip install -U urllib3==1.14如另一个答案所指出的，错误更改为：

Traceback (most recent call last):
  File "/usr/local/bin/docker-compose", line 7, in <module>
    from compose.cli.main import main
  File "/usr/local/lib/python2.7/dist-packages/compose/cli/main.py", 
    line 17, in <module>
    from . import errors
  File "/usr/local/lib/python2.7/dist-packages/compose/cli/errors.py", 
    line 13, in <module>
    from requests.exceptions import ReadTimeout
  ImportError: cannot import name ReadTimeout

Answer 1

看起来您需要安装此软件包。

pip install docker_pycreds

http://packages.ubuntu.com/zesty/python-dockerpycreds

https://github.com/shin-/dockerpy-creds/blob/master/dockerpycreds/constants.py

既然您使用的是Debian衍生产品，那么它将包含在您的产品中。 有关dist / site-packages的详细信息，请参阅此帖子。

dist-packages和site-packages之间有什么区别？

编辑：

您可能需要更新依赖项。

pip install urllib3==1.21

要么

pip install --upgrade urllib3

和/或

pip install --upgrade pip
