Visual studio 2015 VS 2015“；“无法解决依赖关系”；vNext项目编译时出错

我试图将Newtonsoft.json nugget包添加到我的项目中，在编译时出现以下错误：

“NU1001无法解析依赖项Newtonsoft.Json>=7.0.1。”

---

如果我安装的软件包版本可以正常工作，您可以包括Newtonsoft.json 7.0.1。可能您的project.json有问题

这是我的project.json

谢谢你的回复！我的project.json lokos很好。dnu restore没有在该提要中查找包，只查找myget源。我刚刚删除了AppData\Romaing\nuget文件夹中的nuget.config，并在再次还原包时创建了一个新文件夹。现在很好用。奇怪@你的评论对我有用。你应该回答你自己的问题并接受它。我从另一台机器上复制了一个解决方案，结果东西坏了。删除

project.json.lock

文件恢复了包，并且我能够无错误地构建。蝙蝠侠，请添加您在下面答案上留下的评论作为答案。这为我解决了这个问题，也将对其他访客有所帮助。谢谢
