问题描述

在执行恢复我的解决方案的 NuGet 包的命令期间，Bamboo 构建服务器上发生此错误.我可以通过禁用包还原任务来绕过这个错误；但是，这只是一个临时修复.有什么方法可以在运行任务时检查依赖项是否存在?此错误发生在 MSBUILD 运行之前.我正在使用 .NET 4.5

This error occurs on the Bamboo build server during a command that restores my solution's NuGet packages. I can bypass this error by disabling the package restore task; however, this is only a temporary fix. Is there any way I can check if the dependency exists while running the task? This error occurs before MSBUILD is running. I am using .NET 4.5

推荐答案

安装 NuGet 包时，already has a dependency defined for 错误是由于 旧版本 NuGet 中的错误.

The already has a dependency defined for error when installing a NuGet package is due to a bug in older versions of NuGet.

您应该考虑在构建服务器上更新 NuGet，或者运行您自己的构建步骤，该步骤使用您单独下载或部署的 NuGet 版本.

You should look at updating NuGet on the build server or run your own build step that uses a version of NuGet that you download or deploy separately.
