npm ERR!npm可能不是问题。上面可能还有其他日志记录输出。
我的问题是这个问题的扩展(也是我的:)) - > 房间复合主键到外键 所以,如果我有这个类:
public class FoodWithIngredients extends Food{
@Relation(parentColumn = "id", entityColumn = "food_id", entity =
Ingredient.class)
private List<Ingredient> mIngredients;
}

但是PrimaryKey"食物"表是composite (primaryKeys = {"id", "language_id"}).
我如何让@Relation返回记录在哪里"parentColumn = {"id", "language_id"}, entityColumn = {"food_id", food_language_id}"?

ag-grid提供了一种使用api.getSelectedRows()函数获取选定行的方法。并提供一种使用api.setRowData([])功能设置所有行的方法。我正在寻找某种东西getAllRows()来返回网格中的所有行。我知道有一种方法可以使用api.forEachNode()etc 遍历所有行。有什么办法可以获取整个行数组?

错误:

2.ITMS-90209无效的段对齐CitrusGraphics也没有针对PlugNPlay和PayUmoneyCoreSDK框架的正确段.
3.ITMS-90125二进制无效"LC_ENCRYPTION_INFO加载命令中的加密信息丢失或无效或二进制文件已加密.此二进制文件似乎不是用Apple的链接器构建的"
警告:1.ITMS-90080 PayUMoneyCoreSDK.framwork不是独立可执行文件的位置.请确保您的构建设置已配置为创建PIE可执行文件.
我从嵌入式二进制文件中删除了上面的框架,然后上传到app store.Its上传成功,但app store拒绝了app,因为上面的库找不到问题,app最初崩溃了.
我接受了PayUmoney的支持,他们建议再次集成iOS SDK.我这样做但仍然存在问题.
有人请告诉我为什么会这样?去年,旧的iOS SDK工作得很好.一旦我整合了XCODE 9的新更新,那么问题将会提出.我使用Objective-C和XCODE 9.3
