conda install -c conda-forge poppler

Answer 2

下载并安装conda：安装后cmd/Powershell还无法识别
```
conda
```
命令
打开Anaconda Prompt（开始菜单）：运行
```
where conda
```
（给出三个路径）
在 PATH（环境变量）中设置这些，以便终端（cmd）识别它。
- C:\Users\你的用户名\Anaconda3\Scripts
- C:\Users\你的用户名\Anaconda3
- C:\Users\RajaRama\Anaconda3\Library
现在在cmd中测试：
```
conda --version
```
现在运行，
```
conda initi powershell
```
，然后才能在 PS 中使用
