一、關於julia的路徑問題

    先檢視一下，模組或執行的資料夾的路徑是否在引導路徑上，

julia> LOAD_PATH

2-element Array{Union(ASCIIString,UTF8String),1}:

 "D:\\Program Files\\JuliaStudio-0.4.4\\julia-studio\\julia\\local\\share\\julia\\site\\v0.2"

 "D:\\ProgramFiles\\JuliaStudio-0.4.4\\julia-studio\\julia\\share\\julia\\site\\v0.2"      

    如果不在，將需要的路徑增加到引導路徑上。比如，新的模組的路徑為：

path ="D:/Program Files/JuliaStudio-0.4.4/julia-studio/share/qtcreator/Console/myModule";

# 增加模組路徑

julia> push!(LOAD_PATH,path)

3-element Array{Union(ASCIIString,UTF8String),1}:

 "D:\\ProgramFiles\\JuliaStudio-0.4.4\\julia-studio\\julia\\local\\share\\julia\\site\\v0.2"

 "D:\\ProgramFiles\\JuliaStudio-0.4.4\\julia-studio\\julia\\share\\julia\\site\\v0.2"      

 "D:/ProgramFiles/JuliaStudio-0.4.4/julia-studio/share/qtcreator/Console/myModule"    

# 增加資料夾路徑Strategy

julia> push!(LOAD_PATH, "D:/ProgramFiles/JuliaStudio-0.4.4/julia-studio/share/qtcreator/Console/Strategy")

5-element Array{Union(ASCIIString,UTF8String),1}:

 "D:\\ProgramFiles\\JuliaStudio-0.4.4\\julia-studio\\julia\\local\\share\\julia\\site\\v0.2"

 "D:\\ProgramFiles\\JuliaStudio-0.4.4\\julia-studio\\julia\\share\\julia\\site\\v0.2"       

 "D:/ProgramFiles/JuliaStudio-0.4.4/julia-studio/share/qtcreator/Console/myModule"         

 "D:/ProgramFiles/JuliaStudio-0.4.4/julia-studio/share/qtcreator/Console/Strategy"  

   在增加完這些路徑後，系統就可以在這些路徑下查詢你所說的檔案或模組！否則就容易發生類似

“LoadError("D:/ProgramFiles/JuliaStudio-0.4.4/julia-studio/share/qtcreator/Console/test.jl",3,ErrorException("ToolModulenot found"))”

二、 設定當前工作目錄

pwd() :→ Get the current working directory. 獲取當前工作目錄的函式

cd(dir::String) ：Set the current working directory. Returns the new current directory. 設定新的工作目錄

homedir() :→ Return the current user’s home directory.
