Python 尝试在 Anaconda Powershell 上安装时找不到包
Python Package not Found when Trying to Install on Anaconda Powershell
我正在尝试通过 Anaconda Navigator 在 Anaconda 上安装 PyPDF2，以便与 JupyterLab 一起使用。我遇到以下错误：
(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:

PackagesNotFoundError: The following packages are not available from
current channels:

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

and use the search bar at the top of the page.
我也尝试过使用其他一些 Python 软件包，例如 Tabula 和 natsorted，两者都产生了相同的结果。
经过一些研究，我还尝试通过执行以下操作来更改环境：
conda create --name myenv
conda activate myenv
同样，这没有用。如有任何帮助，我们将不胜感激。
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，为什么创建新环境不起作用？如果找不到该命令，您可能必须将 conda 添加到您的 PATH 环境变量中。
