Question

从bitbucket管道部署我的Elastic beantalk应用程序时遇到麻烦。相同的代码一直没有问题，所以我最好的猜测是某种依赖性问题。

（awsebcli版本3.14.1）

管道的图像为python:3.5.2 这是失败的步骤：

- step:
      name: Test Deploy
      deployment: test
      caches:
        - pip
      script:
        - pip install awsebcli --upgrade
        - eb init myAppName -r us-east-1 -p Python  # This line started failing :'(
        - eb deploy myAppName-dev-1

和错误输出：

eb init myAppName -r us-east-1 -p Python Traceback (most recent call last): File "/usr/local/lib/python3.5/site-packages/pkg_resources/__init__.py", line 570, in _build_master ws.require(__requires__) File "/usr/local/lib/python3.5/site-packages/pkg_resources/__init__.py", line 888, in require needed = self.resolve(parse_requirements(requirements)) File "/usr/local/lib/python3.5/site-packages/pkg_resources/__init__.py", line 779, in resolve raise VersionConflict(dist, req).with_context(dependent_req) pkg_resources.ContextualVersionConflict: (PyYAML 4.1 (/usr/local/lib/python3.5/site-packages), Requirement.parse('PyYAML<4,>=3.10'), {'docker-compose'}) During handling of the above exception, another exception occurred: Traceback (most recent call last): File "/usr/local/bin/eb", line 6, in <module> from pkg_resources import load_entry_point File "/usr/local/lib/python3.5/site-packages/pkg_resources/__init__.py", line 3095, in <module> @_call_aside File "/usr/local/lib/python3.5/site-packages/pkg_resources/__init__.py", line 3079, in _call_aside f(*args, **kwargs) File "/usr/local/lib/python3.5/site-packages/pkg_resources/__init__.py", line 3108, in _initialize_master_working_set working_set = WorkingSet._build_master() File "/usr/local/lib/python3.5/site-packages/pkg_resources/__init__.py", line 572, in _build_master return cls._build_from_requirements(__requires__) File "/usr/local/lib/python3.5/site-packages/pkg_resources/__init__.py", line 585, in _build_from_requirements dists = ws.resolve(reqs, Environment()) File "/usr/local/lib/python3.5/site-packages/pkg_resources/__init__.py", line 779, in resolve raise VersionConflict(dist, req).with_context(dependent_req) pkg_resources.ContextualVersionConflict: (PyYAML 4.1 (/usr/local/lib/python3.5/site-packages), Requirement.parse('PyYAML<4,>=3.10'), {'docker-compose'})

因此，如果我没看错，我需要的PyYAML 4.1小于4。

任何有关如何解决此冲突的见解将不胜感激。感谢您的阅读。

我更改了pip安装行，以显式使用旧版本的PyYAML，这似乎行得通...

已更改

pip install awsebcli --upgrade

收件人

pip install pyYAML==3.12 awsebcli --upgrade

eb init失败，出现pkg_resources.ContextualVersionConflict PyYAML 4.1
