Question

线程“ main”中的异常java.io.IOException：文件已存在。这可能会导致不良行为。
请更改扩展类之一的名称。

在这里，我使用的是使用JavaScript的nativescript。当我运行tns run android时出错

File:E:\project\mobile application\ngasceapp\platforms\android\app\sr
lete\AutoCompleteAdapter_autocomplete_63_32_AutoCompleteAdapter.java

我删除了hook，node_module和platform文件夹，并尝试仍然遇到相同的错误。

这是package.json文件

Answer 1

nativescript-ui-dataform插件本身具有nativescript-ui-autocomplete@3.9.0作为依赖项。您的nativescript-ui-autocomplete中有package.json作为依赖项，带有^符号，它将安装最新的主要版本3.10.1。因此，您将拥有2个相同插件的版本，这就是问题的原因。

请尝试删除该^符号并将其保留为3.9.0。

Answer 2

签入您的node_module文件夹。

nativescript-ui-dataform和nativescript-ui-listview也具有node_modules。删除它们并运行tns再次运行android。

由于这两个组件都具有自动完成功能的依赖性，因此您具有相同的多个副本。
