我已经花了几个小时来解决这个问题并尝试了一切，但我无法克服这个障碍。
我打算使用 Apache Cordova 创建一个 APK，同时尝试执行
sdkmanager --list
我得到这个输出：
C:\Windows\system32>sdkmanager --list
Warning: Failed to download any source lists!
Warning: IO exception while downloading manifest
Warning: IO exception while downloading manifest
Warning: Still waiting for package manifests to be fetched remotely.
[=======================================] 100% Computing updates...
以及获取构建工具：
C:\Windows\system32>sdkmanager "build-tools;29.0.0"
Warning: Failed to download any source lists!
Warning: IO exception while downloading manifest
Warning: IO exception while downloading manifest
Warning: Still waiting for package manifests to be fetched remotely.
Warning: Failed to find …我有一个作者和书籍及其地址的架构：
const addr = {
building: String,
block: String,
city: String,
pin: Number
}
const authorSchema = mongoose.Schema({
name: String,
books: [String],
address: addr
});
module.exports = mongoose.model('Author', authorSchema);
现在，当我尝试备份为 JSON 或 CSV 时，出现错误
Path collision at address.building remaining portion building
