python - Hyperledger Indy 节点配置错误导致错误，并显示一条消息: "undefined symbol: indy_crypto_init_logger"

Question

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

你会得到类似的输出

这会导致您运行的命令无法成功完成

Answer 1

这是因为node的python库和libindy-crypto库之间的配置不一致。例如，安装 pip3 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1.9.0 中函数名称更改为 indy_crypto_set_logger。

当您选择使用 pip 安装时，您必须指定 libindy-crypto 库的版本，该版本与您安装的其余部分兼容。

所以不要发出

sudo apt-get install libindy-crypto run this command sudo apt-get install libindy-crypto=0.4.5
