`eb init` 因 pkg_resources.ContextualVersionConflict PyYAML 4.1 而失败

Question

我在从 bitbucket 管道部署我的弹性 beanstalk 应用程序时遇到了一些问题。同样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）

管道的图像是 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，如果我没看错的话，当我需要少于 4 的东西时，我有 PyYAML 4.1。

我更改了 pip 安装行以明确使用旧版本的 PyYAML，这似乎有效...

已更改

pip install awsebcli --upgrade

至

pip install pyYAML==3.12 awsebcli --upgrade
