Files not being obfuscated

Previously I am facing this issue:
"TypeError: Cannot read property 'transformFile' of undefined"

But It is resolved by this code.
getTransformModulePath: () => {
return require.resolve('./transformer');
}

But after creating build, code is not being obfuscated.
And I want to obfuscate single file instead of "src" folder.

Please help.
Thanks.

首先，在将 getTransformModulePath 设置为 require.resolve('./transformer') 后重现构建，然后检查针对生成的构建和 src 文件夹是如何调用 transformer 的。确认混淆单个文件时传入的输入，并验证生成的构建输出已被混淆。
