当您使用 pip 或 pip3 安装 Hyperledger Indy 节点时，您会在运行各种节点脚本（例如 init_indy_keys 和 start_indy_node）时收到此错误。

你得到像这样的输出

AttributeError: /usr/lib/libindy_crypto.so: undefined symbol: indy_crypto_init_logger

这会导致您运行的命令无法成功完成

这是因为 node 的 python 库和 libindy-crypto 库之间的配置不一致。例如，在 pip3 安装后，您将拥有 indy-node 1.8.1。但是，您的 libindy-crypto 版本可能是 1.9.0，并且函数名称在 1.9.0 中更改为 indy_crypto_set_logger。

当您选择使用 pip 安装时，您必须为 libindy-crypto 库指定与您的其余安装兼容的版本。

所以而不是发行

sudo apt-get install libindy-crypto 运行这个命令 sudo apt-get install libindy-crypto=0.4.5
