我想使用基于配对的密码学库，我的链码中没有go语言版本。
我已经运行了官方示例"e2e_cli"。 使用命令"docker ps"，我们可以看到九个docker。

我认为名为"dev-peer0.org1.example.com-mycc-1.0"的码头工人是在节点"peer0.org1"中执行链码的地方。
所以我需要将 pbc 库编程环境添加到 docker 中，例如"dev-peer0.org1.example.com-mycc-1.0"。
但是'dev-peer0.org1.example.com-mycc-1.0'是在安装和实例化链码时自动创建的，我找不到添加库的方法。我没有在文件"docker-compose-cli.yaml"中找到像"卷："设置这样的卷路径。

这是我在链码中使用 PBC 库的部分。

我重新编译了图像--hyperledger/fabric-ccenv：x86_64-1.0.0，添加了我需要的库。因为链码是在基于fabric-ccenv镜像运行的容器中编译的。
