解决方法：

步骤 1：初始化conda的PowerShell支持

打开 Anaconda Prompt（以管理员身份运行）。
执行以下命令：

D:\anaconda3\condabin\conda.bat init powershell

此命令会修改PowerShell配置文件，使conda环境自动激活生效。

3.关闭所有PowerShell窗口和PyCharm。

步骤 2：设置PowerShell执行策略

以管理员身份打开 PowerShell。
输入以下命令允许脚本执行：

Set-ExecutionPolicy RemoteSigned -Force

3. 确认更改后重启PowerShell。

步骤 3：验证conda环境路径

确认环境路径 D:\anaconda3\envs\1-mangguotoutiao 存在。
在Anaconda Prompt中手动激活环境：
```
conda activate 1-mangguotoutiao
```

若激活失败，检查环境是否损坏，必要时重建。

步骤 4：重启PyCharm并测试

完成上述步骤后，重启PyCharm并尝试打开终端。

二 powershell 报错

打开powershell 报错： Windows PowerShell Copyright (C) Microsoft Corporation. All rights reserved. Try the new cross-platform PowerShell https://aka.ms/pscore6 . : File C:\Users\march\Documents\WindowsPowerShell\profile.ps1 cannot be loaded because running scripts is disabled on this system. For more information, see about_Execution_Policies at https:/go.microsoft.com/fwlink/?LinkID=135170. At line:1 char:3 + . 'C:\Users\march\Documents\WindowsPowerShell\profile.ps1' + ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ + CategoryInfo : SecurityError: (:) [], PSSecurityException + FullyQualifiedErrorId : UnauthorizedAccess PS C:\Users\march>

解决方案

步骤 1：以管理员权限打开PowerShell

右键点击“开始菜单” -> 选择 Windows PowerShell (管理员)。

步骤 2：修改执行策略

在管理员 PowerShell中输入以下命令：

Set-ExecutionPolicy RemoteSigned -Scope CurrentUser

RemoteSigned：允许运行本地脚本，远程脚本需签名。
-Scope CurrentUser：仅对当前用户生效，避免影响系统全局。

步骤 3：确认更改

输入 Y 确认更改：

执行策略更改
执行策略可帮助你防止执行不信任的脚本。更改执行策略可能会产生安全风险，如 https://go.microsoft.com/fwlink/?LinkID=135170 中的 about_Execution_Policies 帮助主题所述。是否要更改执行策略?
