VS2017 中的凉亭不工作答案

【问题标题】：bower in VS2017 is not workingVS2017 中的凉亭不工作
【发布时间】：2017-12-28 21:43:25
【问题描述】：

当我使用 bower manager 安装“animate”包时，出现异常：

EMALFORMED Failed to read C:\Users\Frank\AppData\Local\Temp\FRANK-PC-Frank\bower\a2a424217f809672e8fe80ddeab36781-21084-Ho4ioc\bower.json Additional error details: Unexpected token }

我不知道为什么 bower.cmd 没有在项目中修改 bower.json。似乎想修改临时 bower.json（我找不到它，使用 bower logger 提供的路径）。

如何解决？以及为什么 bower 包管理器不好用？

完整日志（vs2017 v15.2）如下：

【解决方案1】：

我遇到了类似的问题。就我而言，这是 Visual Studio 2017 中的一个错误。我更新到了最新版本的 Visual Studio 2017 (15.3)，之后它运行良好。

您可能需要删除 bower.json 文件中的依赖项，然后在更新后通过管理 Bower 包重新添加它们。

【解决方案2】：

我通过手动删除 bower.json 的“依赖项”属性中的所有条目、所有尾随回车符和空格来解决此问题。之后，我右键单击 bower.json 并使用“管理 Bower 包...”并通过该工具重新安装这些包。之后，右键单击“Restore Packages”即可成功检索它们。
