Clojure Datomic:Can'；t从REPL计算d/transaction

我是Datomic on-prem的新手，但我无法从我的编辑处调用d/transact

我启动了对等服务器和事务处理程序

bin/run -m datomic.peer-server -h localhost -p 8998 -a myaccesskey,mysecret -d pensine,datomic:dev://localhost:4334/pensine

我已经把它写在我的缓冲区里了

(def cfg {:server-type :peer-server
          :access-key "myaccesskey"
          :secret "mysecret"
          :endpoint "localhost:8998"})

(def client (d/client cfg))


(def conn (d/connect client {:db-name "datomic:dev://localhost:4334/pensine"}))

// Loaded everything above in the REPL then tried to evaluate the expression below.

(d/transact conn {:tx-data [{:db/ident :red}]}) // this throw the error below
@(d/transact conn {:tx-data [{:db/ident :red}]}) // this throw the error below

答复：

Execution error (IllegalArgumentException) at datomic.client.api.protocols/fn$G (protocols.clj:72).
No implementation of method: :transact of protocol: #'datomic.client.api.protocols/Connection found for class: clojure.lang.Var$Unbound

在我的dev-In-memory设置中，我使用参数启动对等服务器

-d pensine,datomic:mem://pensine

并使用

(def conn (d/connect client {:db-name "pensine"}))

在此设置中，您不需要事务处理程序

希望有帮助，我还没有做过更全面的设置

(def conn (d/connect client {:db-name "pensine"}))
