无法通过 Python 包装器连接到 Hyperledger Indy 测试池 - 错误：找不到 indy.dll

问题描述 投票：0回答：1

我正在尝试使用 

indy-sdk
存储库中的 Docker 映像文件创建并连接到本地 Indy 测试分类帐。但是，我的 Python 代码给出了错误： 
'_load_cdll: Can't load libindy: Could not find module 'indy.dll' (or one of its dependencies).
我还在下面提供了完整的错误文本。我对 Hyperledger Identity Stack 非常陌生，如果有任何帮助，我将不胜感激。

我按照以下步骤创建并连接到我本地的 Indy 账本。 我从 GitHub 克隆了 

indy-sdk
存储库，然后按如下方式运行 docker 映像：

克隆存储库：

C:\Users\Onur\Desktop\indyy>git clone https://github.com/hyperledger-archives/indy-sdk.git

导航到存储库文件夹indy-sdk

C:\Users\Onur\Desktop\indyy>cd indy-sdk

从 docker 文件构建镜像：

C:\Users\Onur\Desktop\indyy\indy-sdk>docker build -f ci/indy-pool.dockerfile -t indy_pool .

输出：

使用“docker scan”对图像运行 Snyk 测试以查找 漏洞并学习如何修复它们

运行容器：

文件也位于与 
pool1.txn
相同的文件夹中。 当我运行 
main.py
连接到本地 indy 账本时，出现错误 
Could not find module 'indy.dll' (or one of its dependencies)
。

main.py文件：

import asyncio
import json

from indy import pool
from indy.error import ErrorCode, IndyError

async def run():
    print("Indy demo program")

    print("STEP1 - Connect to Pool")
    pool_ = {

    }

    print("Open Pool Ledger: {}".format(pool_['name']))
    pool_['genesis_txn_path'] = "pool1.txn"
    pool_['config'] = json.dumps({"genesis_txn": str(pool_['genesis_txn_path'])})

    print(pool_)

    await pool.set_protocol_version(2)

    try:

        print(pool_['handle'])

#loop = asyncio.get_event_loop()

在 ubuntu 系统上您可以下载 https://repo.sovrin.org/lib/apt/xenial/;

然后运行此命令

export LD_LIBRARY_PATH=/path/to/sharedObjectLibrariesFolder

然后就可以了。

在 Windows 上，您需要下载 https://repo.sovrin.org/windows/libindy/

解压它，然后将这些文件放入 windows/system32 中
