尝试在 Anaconda Powershell 上安装时找不到 Python 包

Question

我正在尝试通过与 JupyterLab 一起使用的 Anaconda Navigator 在 Anaconda 上安装 PyPDF2。我面临以下错误:

(base) PS C:\Users\luke.xuereb> conda install PyPDF2 Collecting package metadata (current_repodata.json): done Solving environment:failed with initial frozen solve. Retrying with flexible solve.Collecting package metadata (repodata.json): done Solving environment:failed with initial frozen solve. Retrying with flexible solve.

PackagesNotFoundError: The following packages are not available fromcurrent channels:

• pypdf2

Current channels:

• https://repo.anaconda.com/pkgs/main/win-64
• https://repo.anaconda.com/pkgs/main/noarch
• https://repo.anaconda.com/pkgs/r/win-64
• https://repo.anaconda.com/pkgs/r/noarch
• https://repo.anaconda.com/pkgs/msys2/win-64
• https://repo.anaconda.com/pkgs/msys2/noarch

To search for alternate channels that may provide the conda packageyou're looking for, navigate to

https://anaconda.org

and use the search bar at the top of the page.

我还尝试使用其他一些 Python 包(例如 Tabula 和 natsorted)进行此操作，结果都相同。
我还尝试通过执行以下一些研究来改变环境:

conda create --name myenv
conda activate myenv

同样，这不起作用。任何帮助将不胜感激，谢谢。

Answer 1

通过运行为我工作:conda install -c conda-forge pypdf2因为 pypdf2 包在 conda forge 中有一个包。 https://anaconda.org/conda-forge/pypdf2
编辑:另外，为什么不创建一个新的环境工作？如果未找到该命令，则可能需要将 conda 添加到 PATH 环境变量中。
