beem的好处是,可以自动寻找可用的 steem 服务器节点,大多数时候,不用担心网络访问的问题.
Anaconda的好处是,跨平台管理 python开发环境, 不管你是windows开发者,还是linux/mac的开发者,基本操作都差不多.
本帖以苹果电脑为例(windows/linux未验证).
开源的Python包管理器 anaconda :Anaconda是一个开源的Python发行版本，包含conda、Python、numpy、pandas等上百个科学包及依赖包，下载文件比较大（> 500 MB），如需节省带宽或存储空间，可用Miniconda这个小发行版（仅包含conda和 Python）,再根据需要单独安装需要的包。
beem:是 steem 的一个非官方python库，从 python-bitshares ,包含一个好用的 命令行工具 beempy。
MAC 安装 Anaconda3
beem工具的运行环境要求 Anaconda3 (Python3) ,如果 Anaconda 官方下载太慢,可用清华大学镜像:
$ cd ~
$ wget https://repo.anaconda.com/archive/Anaconda3-2019.10-MacOSX-x86_64.sh
$ bash Anaconda3-2019.10-MacOSX-x86_64.sh
$ source ~/.bash_profile
$ conda activate
(base) ~$ python -V
(base) ~$ pip -V
退出Anaconda3环境:(base) ~$ conda deactivate
Anaconda3 安装 beem
$ cd ~
$ conda activate
(base) ~$ conda config --add channels conda-forge
(base) ~$ conda install beem
(base) ~$ conda install cryptography
使用 beempy
使用最快的节点:$ beempy pingnode --sort
创建本地钱包密码:$ beempy createwallet
查看钱包信息:$ $ beempy walletinfo
+-----------------------+--------------------------------------------+
| Key | Value |
+-----------------------+--------------------------------------------+
| created | True |
| locked | True |
| Number of stored keys | 0 |
| sql-file | /home/xy/.local/share/beem/beem.sqlite |
| password_storage | environment |
| UNLOCK env set | no |
| keyring installed | yes |
+-----------------------+--------------------------------------------+
修改本地钱包密码:$ beempy changewalletpassphrase
添加steem账号:$ beempy addkey
删除steem账号:beempy delkey [OPTIONS] public_key
查看钱包内的steem账号:$ beempy listaccounts
+-----------+---------+-------------------------------------------------------+
| Name | Type | Available Key |
+-----------+---------+-------------------------------------------------------+
| maxxxxnk | active | STMxxxxxx9dvE |
| manbbbbnk | posting | STM87YzixbssssEDKXfU |
+-----------+---------+-------------------------------------------------------+
查询余额:$ beempy balance maxxxxnk manbbbbnk
