Visual Studio中未安装依赖项

Question

我目前正在将ASP.Net RC1升级到ASP.Net Core RC2.Visual Studio中的解决方案资源管理器通过子文件夹"npm - not installed"向我发出"Dependencies - not installed"的警告.

但是,似乎安装了依赖项 - 我在项目目录中运行'npm install'并且运行正常,没有任何错误,只是一些警告.它将依赖项文件夹添加到名为node-modules的父文件夹中,我可以在Windows资源管理器中清楚地看到它.node-modules文件夹包含angular2,bootstrap,copy-webpack-plugin等文件夹.

有谁知道为什么Visual Studio告诉我他们没有安装？我还尝试从Package Manager Console运行npm install,并在这些文件夹上执行"右键单击 - >还原包",在解决方案资源管理器中给出警告.

这是我的package.json文件:

Answer 1

在创建ASP.NET Core Web Application (.NET Framework 4.5.2)使用时,这仍然是Visual Studio Community 2015,Update 3版本中的一个问题Empty ASP.NET Core Template.使用ASP.NET Core Web应用程序模板创建项目时,它似乎正常运行.

正如操作中提到的那样,由于安装了依赖项,因此该消息具有误导性.Visual Studio似乎只是误报了npm和依赖项没有安装.临时修复是覆盖Visual Studio正在寻找node.js的位置,这会删除not installedvisual studio 中的消息.

在Visual Studio中,转到Tools > Options > Projects and Solutions > External Web Tools并添加node.js安装的路径.这默认位于C:\Program Files\nodejs\或C:\Program Files (x86)\nodejs\将此新行移至顶部或至少高于$(VSINSTALLDIR)\ Web\External行.

恢复您的包,错误消息应该消失.

我认为这是在asp github上报道的RC2的已知问题

https://github.com/aspnet/Tooling/issues/479

我认为功能应该可行,但消息是错误的,所以我们可能需要等到他们解决问题.

这似乎是由于NPM对无法安装的组件发出警告,例如OSX组件(如果您在Windows上).VS将其解释为失败,而实际上并非如此. 更多细节在这里.
