[英]Trying to run a scala script, conscript errors when install “sbt/sbt”
我正在嘗試在OSX上使用應征腳本安裝sbt / sbt
cs sbt/sbt --branch 0.13.8
遵循sbt doc: http : //www.scala-sbt.org/release/docs/Scripts.html
我收到以下錯誤:
.......

Conscripted sbt/sbt to ~bin/sbt
Conscripted sbt/sbt to ~/bin/scalas
Conscripted sbt/sbt to ~/bin/screpl
scalas
和screpl
似乎已正確安裝? 但是,當我嘗試執行以下腳本helloworld.scala
,
#!/usr/bin/env scalas
/***
scalaVersion := "2.11.6"
*/
println("hello")
我收到如下錯誤:
>./helloworld.scala
~ ./helloworld.scala:5: error: eof expected but ';' found.
*/
^
[error] Error parsing expression. Ensure that settings are separated by blank lines.
另一個腳本示例test.scala
:
#!/usr/bin/env scalas
/***
scalaVersion := "2.11.6"
libraryDependencies += "net.databinder.dispatch" %% "dispatch-core" % "0.11.2"
*/
import dispatch._, Defaults._
case class Location(city: String, state: String)
def weatherSvc(loc: Location) = {
host("api.wunderground.com") / "api" / "5a7c66db0ba0323a" /
"conditions" / "q" / loc.state / (loc.city + ".xml")
}
val nyc = Location("New York", "NY")
for (str <- Http(weatherSvc(nyc) OK as.String))
println(str)
我收到如下錯誤:
./test.scala:18: error: not found: value Location
val nyc = Location("New York", "NY")
^
./test.scala:14: error: not found: value host
host("api.wunderground.com") / "api" / "5a7c66db0ba0323a" /
^
./test.scala:13: error: not found: type Location
def weatherSvc(loc: Location) = {
^
sbt.compiler.EvalException: Type error in expression

有人可以建議嗎?
原來最后一條注釋行開頭的空白( " */"
)失敗。 IntelliJ自動添加空間以美化注釋(或者添加空白是scala約定?),但是scalas
不會刪除它。
