Compilation参数必须是office外接程序中编译错误的实例

Question

我是office插件开发的新手，但在我们的组织中有一个项目。安装完package.json文件中提到的所有依赖项后，当我尝试运行'npm run dev-server‘时，得到以下错误：

c:\git\sample-project\ui-addin>npm run dev-server

> ui-addin@1.0.0 dev-server c:\git\sample-project\ui-addin
> webpack-dev-server --mode development

我使用'npm ls webpack‘验证了安装的webpack版本，并使其完全相同。但目前还不走运。这个相同的应用程序正在另一个用户的机器上运行文件，他可以运行插件，但我不知道为什么我会得到这个错误。

这个问题与Windows、Powershell以及区分大小写的方式有关。我知道您使用Powershell，因为如果您只是打开一个命令提示符，就不会出现这个问题。(这可能在一定程度上解释了为什么它在同事的工作站上工作。)

使用命令提示符或找到目录的确切大小写(例如，使用资源管理器)，并在Powershell中使用大小写。

上面显示的路径是：c:\git\sample-project\ui-addin。

作为演示，我将在本地命令提示符下创建与您相同的目录：

C:\>mkdir git\sample-project\ui-addin
C:\>cd git\sample-project\ui-addin
C:\git\sample-project\ui-addin>

让我们转到Powershell中的同一目录：

PS C:\> cd Git\Sample-Project\Ui-ADDIN\
PS C:\Git\Sample-Project\Ui-ADDIN>

哈?Powershell将严格遵守我使用的任何用例，但也会维护它！我对这个问题的挖掘还不够深入，无法真正理解背后发生了什么，但不管是什么，对npm和Webpack来说，有问题就足够了。

不管它有什么价值，命令shell将不会接受除原始情况以外的任何情况：

C:\>cd Git\Sample-PROJECT\UI-addin\
C:\git\sample-project\ui-addin>

虽然许多资源帮助我解决了这个问题，但this Github issue帮助我理解并解决了它。
