npm - VS2015 CTP6 中嵌套 node_modules 的 "FullPath cannot be applied"错误

Question

我在 Visual Studio 2015 CTP6 中玩弄 MVC6 + Aurelia 项目，遇到了一些有趣的事情。

我的 node_modules默认情况下在项目根目录中，一切正常。但是，我想让源代码树更有条理和移动node_modules , jspm_modules以及与子文件夹相关的内容 - 例如。 MyApp\client\node_modules等等。

但现在 Visual Studio 停止加载项目。这是来自“VsProjectFault.failure.txt”的异常:

(Inner Exception #1) System.InvalidOperationException: The item metadata "%(FullPath)" cannot be applied to the path "client\node_modules\conventional-changelog\node_modules\lodash.assign\node_modules\lodash._basecreatecallback\node_modules\lodash.bind\node_modules\lodash._createwrapper\node_modules\lodash._basecreatewrapper\node_modules\".

显然问题出在 node_modules递归路径太长 - 还有 bug #6960在节点跟踪器中

Node needs an alternative approach to endless, recursively nested node_modules folders on Windows. Most Windows tools, utilities and shells cannot handle file and folder paths longer than 260 characters at most.

...这似乎是 closed as won't fix对我来说:

Node isn't going to change, so this isn't really a Node issue. The problem is not with the module loading semantics, but with the module installation semantics. (The two are related, but not identical.)

但后来我不明白这个项目是如何加载的，因为即使 node_modules，有些路径肯定超过 260 个符号。在项目根目录下!

配置中是否有一些设置或有助于 Visual Studio 2015 加载项目的内容 node_modules ， 这是怎么回事？

这是因为 VS 中文件路径的字符限制已经越界。将文件夹复制到根文件夹中并尝试。
