我是 VS 代码的新手，并尝试安装一些扩展。

在以下页面中，有一个名为“ Install the Extension Pack for Java”的按钮，而“ ”的链接Install the Extension Pack for Java为“ vscode:extension/vscjava.vscode-java-pack”：

https://code.visualstudio.com/docs/languages/java

如何安装带有字符串“ vscode:extension/vscjava.vscode-java-pack”的 VS 代码扩展？

我尝试复制“ vscode:extension/vscjava.vscode-java-pack”并将其粘贴到 VS code 窗口顶部的搜索栏中，但没有运行安装程序。我还尝试将其粘贴到 VS code 窗口左侧的扩展选项卡内的搜索框中，但找不到该扩展。

我需要手动将名称“ vscjava.vscode-java-pack”复制到扩展选项卡内的搜索框中，然后单击Install右侧扩展网页中的“ ”来安装此扩展。

它是 VS 代码命令还是只是一个简单的字符串？

我通过以下命令在 Ubuntu 上安装了 python 软件包：

# pip install --upgrade -r r.txt

这是控制台输出：

Installing collected packages: protobuf

ERROR: pip's legacy dependency resolver does not consider dependency conflicts when selecting packages. This behaviour is the source of the following dependency conflicts.
apache-beam 2.53.0 requires packaging>=22.0, but you'll have packaging 20.9 which is incompatible.
ortools 9.8.3296 requires absl-py>=2.0.0, but you'll have absl-py 1.4.0 which is incompatible.
ortools 9.8.3296 requires pandas>=2.0.0, but you'll have pandas 1.5.3 which is incompatible.

Successfully installed protobuf-4.25.1
#

关闭控制台后，我想重新打开终端以检查系统中存在哪些依赖问题。

这是预期的输出：

# pip what_command_to_show_the_problem

使用什么命令可以显示dependency problem系统中存在相同的内容？

我想生成随机数，然后将其用作“ index”从其他数组列表中获取数据。

给定一个数5，然后生成5 numbers的序列[1..5]，然后将shuffle它们变成随机的顺序。

以下是打乱数字后的两个输出示例：

1, 3, 5, 2, 4
2, 5, 1, 4, 3

给定一个数字100，然后生成100 numbers，[1...100]然后使用相同的方法对它们进行洗牌。

现在在 bash 中定义一个 shuffle 函数：

shuffle_numbers() {
    local range="$1"
    
    # Use method from "Mark Setchell"
    # numbers=( $seq 100 | shuf )
    
    # The value of numbers should be:
    # 1, 3, 5, 2, 4
    # or
    # 2, 5, 1, 4, 3
    # or
    # ..other random orders if the $range is 5.
    # or
    # ... 100 random orders if the $range is 100...
    
    sprintf "%s" "$numbers"
}

如何shuffle_numbers在bash中实现？
