我正在努力解决这个错误消息.有时在升级或重新启动编辑器后,我无法在Visual Studio代码上运行xdebug.这是错误的屏幕截图:

谁能帮我这个？

在 Sequelize v5 上配置模型之间的关联时，出现了这样的错误。

我想使用 Nestjs 和 TypeORM 在 PostgreSQL 中实现数据库行锁定。请任何人告诉我如何以正确的方式实施它。我尝试使用以下代码，但不确定它是否锁定特定行。

async testFun(): Promise<any> {
        const user = await this.userRepo
                    .createQueryBuilder("user")
                    .useTransaction(true)
                    .setLock("pessimistic_write")
                    .where("id = :id", { id: 2 })
                    .getOne()

        const updateResult: any = await this.userRepo.createQueryBuilder('test')
                                .update()
                                .set({ fullname: "frm3000" })
                                .where("id = :id", { id: 2 })
                                .execute();
        
        return updateResult;
    }

TypeORM 生成的查询是，

query: START TRANSACTION
query: SELECT * FROM "users" "user" WHERE id = $1 FOR UPDATE -- PARAMETERS: [2]      
query: COMMIT
query: UPDATE "users" SET "fullname" = $1 WHERE "id" …

我在 ubuntu 14.04 上启动 docker 服务并尝试启动 postgres 容器后刚刚收到这些消息。

$ docker start codeslave-postgres --> starting my container
$ Error response from daemon: network bridge not found
$ Error: failed to start containers: codeslave-postgres

我试图停止并重新启动 docker 服务，也重新启动我的机器，但它似乎不够工作。那么这些消息的含义是什么？
