linux - SublimeREPL scala 错误...同样的错误，但现有的解决方案无法解决问题

Question

运行SublimeREPL:打开文件夹的SBT时，我遇到了与The similar question asked before中完全相同的问题(OSError(2, '没有这样的文件或目录'))。

不幸的是，那里提供的解决方案并没有多大帮助。

有人愿意提供一些线索来说明这里仍然可能存在问题吗？

我目前运行的是 Ubuntu 12.04。

我的Main.sublime-menu配置如下:

[

    "id": "tools",
    "children":
    [{
        "caption": "SublimeREPL",
        "mnemonic": "r",

             "children":[

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

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

此外，scala 和 sbt 系统路径也是这样定义的

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

Answer 1

你的道路混淆了。 "caption": "scala REPL" 菜单项以 scala 作为其命令，但扩展的 PATH 为 /home/helluin/apps/sbt/bin。 "caption": "SBT for openingedfolder" 项以 sbt 作为其命令，但扩展 PATH 为 /usr/bin。你应该切换它们。

或者，对于 Scala REPL，创建命令的第一行:

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

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

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

然后您就无需担心扩展该特定环境变量。
