My Julia REPL Help为加载路径提供了以下内容:

help?> LOAD_PATH
search: LOAD_PATH

  LOAD_PATH

  An array of paths for using and import statements to consdier as project environments or package directories when
  loading code. See Code Loading.

下面是我在提示符处对LOAD\u PATH的输出:

julia> LOAD_PATH  # What is the output below?
3-element Array{String,1}:
 "@"
 "@v#.#"
 "@stdlib"

有什么建议吗?

DEFAULT_LOAD_PATH

请允许我引用 relevant section of the source code

## LOAD_PATH, HOME_PROJECT & ACTIVE_PROJECT ##

# JULIA_LOAD_PATH: split on `:` (or `;` on Windows)
# first empty entry is replaced with DEFAULT_LOAD_PATH, the rest are skipped
# entries starting with `@` are named environments:
#  - the first three `#`s in a named environment are replaced with version numbers
#  - `@stdlib` is a special name for the standard library and expands to its path

换句话说,

"@" :用于加载相对于当前路径的内容(此处不完全确定,请参阅下面的更新)
"@v#.#" :将成为 v1.0
"@stdlib" :将成为stdlibs的路径

filing an issue over there ? (更新:请参阅 https://github.com/JuliaLang/Pkg.jl/issues/757

更新:

Base.load_path_expand(a::AbstractString) 最终变成什么:

julia> Base.load_path_expand.(LOAD_PATH.*"/test")
3-element Array{String,1}:
 "\\test\\Project.toml"
 "C:\\Users\\carsten\\.julia\\environments\\v1.0\\test\\Project.toml"
 "C:\\Users\\carsten\\.julia\\environments\\stdlib\\test\\Project.toml"
