Question

使用pip或pip3安装Hyperledger Indy节点时，在运行各种节点脚本（如init_indy_keys和start_indy_node）时会出现此错误。

这会导致您运行的命令无法成功完成

Answer 1

这是因为节点的python库和libindy-crypto库之间的配置不一致。例如，在安装pip3之后，您将拥有indy-node 1.8.1。但是，您的libindy-crypto版本可能是1.9.0和函数名称在1.9.0中更改为indy_crypto_set_logger。

选择使用pip安装时，必须为libindy-crypto库指定一个与其余安装兼容的版本。

因此，不是发出

sudo apt-get install libindy-crypto 运行此命令 sudo apt-get install libindy-crypto = 0.4.5

错误配置od Hyperledger Indy节点导致错误，并显示消息“未定义符号：indy_crypto_init_logger”
