版本号搞得鬼！Winsows VSCode 和 Trae 的 Terminal 不识别 conda 环境

问题简述

在 Win 11 系统自带的终端(Powershell)和CMD窗口中，可以正常调用conda，命令行回显：

(base) PS C:\Users\DELL>

然而，在 VSCode 和 Trae 上无法正确使用 conda 报错为：

PS C:\Users\DELL> conda activate base  
Invoke-Expression: Missing '{' in configuration statement.

版本号

在 CMD 窗口中，$PSVersionTable 命令无效。
在 Windows Powershell 窗口中，$PSVersionTable 命令回显：

(base) PS C:\Users\DELL>  $PSVersionTableName                           Value
----                           -----

WSManStackVersion              3.0
PSRemotingProtocolVersion      2.3
SerializationVersion           1.1.0.1

在VSCode的Terminal窗口中，$PSVersionTable 命令回显：

PS C:\Users\DELL>  $PSVersionTableName                           Value
----                           -----

尝试1：使用 conda init powershell

在 Windows Powershell 中执行后回显：

(base) PS C:\Users\DELL> conda init

no change     D:\software\miniconda\Scripts\conda-env.exe

尝试在 VSCode 中执行相同的命令，回显：

PS C:\Users\DELL> conda init powershell

实际上并没有被调用起来。

解决

Conda在PowerShell 7.5版本中会失效。可以通过升级 conda 软件来处理。

https://github.com/PowerShell/PowerShell/issues/24869#issuecomment-2625708821

1. 首先切换到 base 环境 conda activate base
2. 升级 python 版本 conda update python (按需指定版本号)
3. 升级 conda 版本 conda update conda (按需指定版本号)

即解决。
