npm run dev:h5报错 ValidationError: CopyPlugin Invalid Options

[jd_43016a4b14dbb]

环境配置好后，通过taro init taro-demo下载默认模板，然后进入项目下运行npm run dev:h5 提示“ValidationError: CopyPlugin Invalid Options options should NOT have fewer than 1 items” 试过了几个npm版本和@tarojs/cli版本，都报同样的错误。

同问

[340524803-350620]

我也是！！
今天重新安装了下包，就这样完犊子了！

[jd_7d4f0252e39f3]

@340524803-350620 莫慌莫慌

[jd_7d4f0252e39f3]

@jd_7d4f0252e39f3 用你之前的moduel就行了

[340524803-350620]

@jd_7d4f0252e39f3 原包已经没了，现在就很尴尬了。

[jd_4bc26a69d5ab1]

copy-webpack-plugin升级到5.1.0了，没有兼容5.0.x版本的api，着急的话自己的项目可以重新安装下5.0.x版本的。后续还是需要taro库本身自己升级下的

[jd_4bc26a69d5ab1]

例如在使用copy-webpack-plugin时，传入参数：
new CopyWebpackPlugin(
needCopyFiles,
options
)
needCopyFiles 这里的参数不能为空数组

@jd_4bc26a69d5ab1 谢谢，解决了！请问你怎么发现是copy-webpack-plugin插件版本问题的？

[校尉]

此回复已被删除！

[jd_4bc26a69d5ab1]

@1832508391-186202 我有一个项目用到webpack这个插件了，也遇到了这个问题，查看这个包升级记录发现的。我不是taro的使用者，偶然发现这个论坛的，就上来答一下

[340524803-350620]

@校尉 我天，我安装5.0.x的 依旧不行

[jd_7d6ed4528ec2a]

@340524803-350620 我能运行，但页面一片空白

执行了cnpm install -D copy-webpack-plugin@5.0 还是报错

[340524803-350620]

@74803280-83886664 手动配置吧，在config/index.js 下的copy.patterns 里配置一个静态资源的吧

我这样就可以了

[小红姑娘1002]

我也是这个差不多这个报错我好南

[小红姑娘1002]

@小红姑娘1002 运行了上面说的5.0的代码就运行出空白

[校尉]

@340524803-350620 啊，不应该啊，我的安装下就好了

[340524803-350620]

@校尉 我这边不行，坑死。自己手动配了参数，现在OK了

[东园居士]

@340524803-350620 我这边也不行，想问一下你是怎么配置的
