建立了Azure DevOps python feed，并发布了python程序包，但无法将其安装在我的管道中。

  displayName: 'Pip Authenticate'
  inputs:
    artifactFeeds: my_feed
    onlyAddExtraIndex: true
- script: pip install my-package==0.0.1234

DEPRECATION: Python 2.7 will reach the end of its life on January 1st, 2020. Please upgrade your Python as Python 2.7 won't be maintained after that date. A future version of pip will drop support for Python 2.7. More details about Python 2 support in pip, can be found at https://pip.pypa.io/en/latest/development/release-process/#python-2-support

Answer 1

pip安装时出现Azure Azure DevOps python feed错误

首先，您需要仔细检查Feed中该软件包的版本0.0.1234。

第二，根据错误消息，似乎您正在使用Python 2.7，请尝试将Python更新为3.6.x。

第三，将python更新到3.6.x时，您仍然遇到相同的问题，请尝试使用以下方法将pip升级到最新版本：

py -m pip install --upgrade pip

在创建软件包时使用的python版本应与   安装期间使用的版本。

例如如果在/ dist文件夹中，则有my-package-0.0.1234-py3-none-any.whl   您应该使用python版本3安装它。否则，您将获得   此错误消息。

我猜my-package-0.0.1234-py2-none-any.whl将显示相同的错误   如果您尝试使用python 3安装它。

希望这会有所帮助。

Answer 2

在创建软件包时使用的python版本应与安装期间使用的版本匹配。

例如如果在/dist文件夹中有 my-package-0.0.1234-py3-none-any.whl ，则应使用python 3版本安装。否则，您将收到此错误消息。

我想如果您尝试使用python 3安装my-package-0.0.1234-py2-none-any.whl也会显示相同的错误。
