嘿哟。

我一直在努力运行软件包，可能需要一些帮助。这是我到目前为止所做的：

  1. 使用Pkg生成一个名为Void的项目

  2. 添加了CSV和DataFrames作为依赖项（已在 TOML 中列出）

  3. 查看项目状态（包括两个库）

  4. 实例化

但是，我的项目仍然不会运行任何包含这些库的内容。这是我的代码：

# src/Void.jl
using CSV, DataFrames

module Void
    function testing()
        frame = CSV.read("sheet.csv", DataFrame)
        print(frame)
    end
end

Void.testing()

export Void

我尝试julia --project=. src/Void.jl运行这个脚本，但它给了我UndefVarError: `CSV` not defined.

尝试julia --project=.按此using Void顺序抛出一个错误，指出 CSV 也不是依赖项。

ERROR: LoadError: ArgumentError: Package Base does not have CSV in its dependencies:
- You may have a partially installed environment. Try `Pkg.instantiate()`
  to ensure all packages in the environment are installed.
- Or, if you have Base checked out for development and have
  added CSV as a dependency but haven't updated your primary
  environment's manifest file, try `Pkg.resolve()`.
- Otherwise you may need to report an issue with Base

我也尝试按照错误提示执行操作，但没有成功。我究竟做错了什么？
