Question

我已经为此战斗了一段时间。当我运行npm run dev时，出现以下错误。我可以运行webpack -mode dev，它可以工作。它将输出直接放入我的dest目录中。这是我的项目的GitHub和Git Clone Link。

我正在跑步：
-节点：v12.16.1
-Webpack：4.42.1
-webpack-cli：3.3.11

错误输出：

> @ dev %USERPROFILE%\source\repos\simple-router
> webpack --config webpack.config.dev.js -mode development --display-error-details

我将其发布在这里，可能有帮助，我在google上搜索了我的问题，并找到了该主题。

在我的情况下，

我有一个自定义的“ optin” arg，我用来默认情况下不包含在基本版本中的optin功能。我这样做是因为在同一个项目中我有多个条目和多个输出，并且某些条目并非总是必需的，所以我让用户选择使用它。

一切正常，但有一天我拼错了并写了：npm run build.prod -- -optin=myfeature，但出现此错误，因为它在optin参数之前缺少一个“-”。

因此，启用了-o参数，它使webpack输出混乱

Webpack类型错误'TypeError [ERR_INVALID_ARG_TYPE]：“路径”参数必须为字符串类型。收到的类型为布尔值（true）'
