Visual Studio 2015社區中的Aurelia捆綁包

Question

我在package.json設置了一個postinstall規則，如下所示：

"postinstall": "aurelia bundle --force"

如果我從項目文件夾中的cmd運行npm install ，則不會顯示任何錯誤，但是當項目在Visual Studio 2015社區中加載時，它會在“輸出”窗口中顯示以下錯誤（但輸出捆綁的文件）：

---> (Inner Exception #0) Microsoft.NodejsTools.Npm.PackageJsonException: Error reading package.json at '...\node_modules\aurelia-cli\node_modules\npm\node_modules\graceful-fs\package.json': Error reading package.json. The file may be parseable JSON but may contain objects with duplicate properties.

The following error occurred:

Can not add Newtonsoft.Json.Linq.JValue to Newtonsoft.Json.Linq.JObject. ---> Microsoft.NodejsTools.Npm.PackageJsonException: Error reading package.json. The file may be parseable JSON but may contain objects with duplicate properties.

那么從Visual Studio自動運行npm install是否對腳本的實際捆綁有任何影響，就意味着它在自動運行時會跳過某些模塊嗎？

Answer 1

Visual Studio 2015使用非常舊的Node和npm版本。 我在適用於Apache Cordova應用程序的工具中遇到了類似的問題。

您可以通過更改C：\\ Program Files（x86）\\ Microsoft Visual Studio 14.0 \\ Common7 \\ IDE \\ Extensions \\ Microsoft \\ Web Tools \\ External下的某些文件（包括node.exe）來使vs使用與cmd相同的Node和npm。

尋找這篇文章http://jameschambers.com/2015/09/upgrading-npm-in-visual-studio-2015/

此外，vs似乎不適用於最新的5.0.0節點。 用4.2.2代替一個解決。
