SublimeREPL scala错误..。相同的错误，但是现有的解决方案没有解决这个问题。

Question

在运行SublimeREPL: SBT for opened folder时，我遇到了与The similar question asked before (OSError(2, 'No such file or directory'))完全相同的问题。

不出所料，在那里提供的解决方案没有多大帮助。

有谁愿意给我们一些线索，看看这里还有什么问题吗？

我目前正在运行Ubuntu12.04。

我的Main.sublime-menu配置如下：

    "id": "tools",
    "children":

                },
                {"command": "repl_open",
                 "caption": "SBT for opened folder",
                 "id": "repl_sbt",

                                   "linux": {"EMACS": "1", "PATH": "{PATH}:/usr/bin"},
                                   "windows": {"EMACS": "1"}},
                    "suppress_echo": false, 
                    "syntax": "Packages/Scala/Scala.tmLanguage"
                    }
                } 
            ]}
        ]
    }]
  }
]

此外，还定义了scala和sbt系统路径。

λ →  which scala
/usr/bin/scala
λ →  which sbt
/home/helluin/apps/sbt/bin/sbt

Answer 1

你的路搞混了。"caption": "scala REPL"菜单项的命令是scala，但扩展的PATH是/home/helluin/apps/sbt/bin。"caption": "SBT for opened folder"项的命令是sbt，而扩展的PATH是/usr/bin。你应该换一下。

或者，对于Scala，执行命令的第一行：

"cmd": {"linux": ["/usr/bin/scala"],

(尽管/usr/bin应该已经在系统PATH中了)。对于sbt REPL，执行命令的第一行：

"cmd": {"linux": ["/home/helluin/apps/sbt/bin/sbt"],

然后您就不需要担心扩展特定的环境变量了。
