在路径{appPath}下，未找到package.json文件

Error message

在路径{appPath}下，未找到package.json文件

What it means

ModifyPackageJson(appPath) edits <appPath>/package.json (backing it up first, then rewriting the main field). If package.json is absent it throws a plain Exception, because appPath did not resolve to QQNT's real app directory.

Solutions

1. Verify the QQNT install path (must contain QQ.exe).
2. Ensure versions\<ver>\resources\app\package.json actually exists.
3. Reinstall QQNT to repair the app folder if it is corrupted.

string packageJsonPath = Path.Combine(appPath, "package.json");
if (!File.Exists(packageJsonPath))
{
    MessageBox.Show($"{appPath} 下未找到 package.json，请确认安装路径是否正确。");
    return;
}
ModifyPackageJson(appPath);

When it happens

Trigger: appPath lacks package.json. Happens when the install path is wrong, when GetAppPath fell through to <install>/resources/app (because the versions folder was missing/empty) where no package.json exists, or when the app directory is corrupted.

Common situations: Wrong folder chosen (not the QQNT root); QQNT installed in a non-standard layout; versions folder exists but holds no version subdir.
