Flatter尝试访问根目录，但失败，但我希望Flatter访问主目录。 如何修改它

命令 颤振-v创建hello_世界

例外 FileSystemException:FileSystemException:Exists失败，路径='/root/.pub cache/hosted/pub.dartlang.org/flatter_template_images-1.0.0/lib/'（操作系统错误：权限被拒绝，错误号=13）

           AOT snapshots can be obfuscated: that is all identifiers will be renamed    
           during compilation. This mode is enabled with --obfuscate flag. Mapping     
           between original and obfuscated names can be serialized as a JSON array     
           using --save-obfuscation-map=<filename> option. See dartbug.com/30524       
           for implementation details and limitations of the obfuscation pass.
