我运行blockchainr并获得以下终端输出:

我在OSX Yosemite 10.10.3上运行go go version.4.4.2 darwin / amd64
代码位于https://github.com/FiloSottile/blockchainr
我运行的具体命令(按顺序)是:
最后一个命令是我得到这个终端输出的地方。
答案 0 :(得分:0)
问题在于Blockchainr main.go以下几行:
var (
dataDir = flag.String("datadir", filepath.Join(btcutil.AppDataDir("btcd", false), "data"), "BTCD: Data directory")
dbType = flag.String("dbtype", "leveldb", "BTCD: Database backend")
)
如您所见,如果您未指定dbtype
标志,则默认为"leveldb"
,因此它希望datadir
参数包含LevelDB数据库的路径。
