安装powershell最新版#

由于我使用的是最新版（因为用旧版遇到了各种各样的问题），所以我选择先安装powershell的最新版输入以下指令

1
# 使用winget安装powershell，当然你也可以用scoop，但是我忘记怎么安装scoop了
2
winget install --id Microsoft.PowerShell --source winget
3

4
# 验证安装成功
5
pwsh --version
6
# 这里应该出现类似PowerShell 7.5.4的输出
7

8
# 查找安装目录（可选）
9
where.exe pwsh
10
# 不能直接where我实在是不理解
11

12
# 或者你也可以这样
13
Get-Command pwsh
14
# powershell的指令是真长

现在你应该安装好了最新版的powershell，让我们进入下一步

安装字体#

为了之后的主题能正常显示，我们这里先安装字体

首先，在字体网站下载字体
右键
然后安装注意，需要有管理员权限

配置windows terminal#

修改默认配置文件#

首先右键点击windows标签栏空白处
点击设置
更改默认配置文件为我门刚刚安装的powershell

具体配置#

得益于windows terminal的图形化界面，我们不用直接更改配置文件，只需要在图形化的界面中操作就行了

点击外观，在这里你可以随意修改，这是我的配置，仅供参考
点击我们之前安装的powershell的配置文件，在这里你可以选择图标和其他的一些配置
点击外观，修改字体为FiraCode Nerd Font，当然你也可以使用JetBrains Mono，其余如光标形状等也可以自行修改，这是参考配置:
- 配色方案: Cambell
- 字体: FiraCode Nerd Font
- 全色表情符号: true
- 光标形状: 实心框
- 背景图像: 自行选择
- 背景图像拉伸模式: 均匀填充(其他模式我感觉有点奇怪)
- 背景图像对齐: 居中
- 背景图像不透明度: 40%
- 背景不透明度: 随意，如果有背景图像的话，这个不起什么作用
- 启用亚克力材料: 同上
如果启用了背景图像，建议不透明度调低一点，不然字可能有点难看清

以下是最终的配置文件

常见?问题#

python虚拟环境显示问题#

有的主题不支持显示python的虚拟环境，例如我当前使用的主题catppuccin 它原来的配置文件是这样的:

64
        }
65
      ],

67
    }
68
  ],
69
  "final_space": true,
70
  "version": 3
71
}

里面的segment没有一个的type是python，也就是说，它不支持显示python的虚拟环境显示但是我们可以手动向里面添加segment使得它支持python环境显示，我添加在path之前，这决定了虚拟环境显示名称的位置：

1
        {
2
          "background": "p:miku",
3
          "foreground": "p:wight",
4
          "type": "python",
5
          "style": "powerline",
6
          "properties": {
7
          "display_mode": "environment",
8
          "fetch_virtual_env": true,
9
          "home_enabled": true,
10
          "folder_name_fallback": false
11
          },
12
          "template": "  {{ .Venv }}"
13
        },

这里的背景色(foreground)是我自定义的miku 在palette 里添加"miku":"#39C5BB"即可(你也可以添加任意的名称-颜色十六进制代码组合) 于是，修改后的代码就是这样的:

1
{
2
  "$schema": "https://raw.githubusercontent.com/JanDeDobbeleer/oh-my-posh/main/themes/schema.json",
