无法设置 IP 表：无法启用 NAT 规则

Question

我正在做这个教程：https://hyperledger.github.io/composer/latest/installing/development-tools

现在我想启动超级账本结构，./startFabric.sh但随后出现此错误：

dany@DESKTOP-IQB2P0B:~/fabric-dev-servers$ ./startFabric.sh
Development only script for Hyperledger Fabric control
Running 'startFabric.sh'
FABRIC_VERSION is set to 'hlfv12'
FABRIC_START_TIMEOUT is unset, assuming 15 (seconds)
Removing network composer_default
WARNING: Network composer_default not found.
Creating network "composer_default" with the default driver
ERROR: Failed to Setup IP tables: Unable to enable NAT rule:  (iptables failed: iptables --wait -t nat -I POSTROUTING -s 172.22.0.0/16 ! -o br-b49f324730b7 -j MASQUERADE: iptables: No chain/target/match by that name.
 (exit status 1))

在出现此错误之前：https ://github.com/docker/compose/issues/4181

但我修复了它，现在我遇到了这个错误......

尝试：

sudo iptables -t filter -N DOCKER

sudo systemctl restart docker
