fiona Importerror：...库未加载： @rpath/libpoppler.91.dylib

Question

今天，我在Mac（Macos Monterey 12.2）上重新安装了Anaconda（Anaconda 3，Python 3.9）。我通过 conda-forge 安装了geopandas，并在我的 base 环境的python中成功进口了它（3.9.12）。然后，我也安装了salem通过 conda-forge ，在python失败，返回：

>>> import salem

阅读此书，我尝试在一个新的控制台，它给了我此错误消息：

我在Conda软件包管理方面没有太多经验。当我运行conda列表时，我会得到以下内容（删节）：

我只包括 conda-forge packages，因为我的帖子太长了，以至于否则会被添加。如果需要，我可以提供conda列表的完整输出。尽管如此，这些包装似乎就在那里。

有什么想法要解决这个问题吗？感谢您的帮助。

其他信息

我还尝试了

conda create -n test
conda activate test
conda install -c conda-forge fiona

，安装再次成功。但是，导入fiona在测试环境的Python中仍然提供相同的错误消息。

有关GitHub上这篇文章的相关问题

似乎对待一个非常相似的问题： https：// https：// https：// github.com/conda-forge/geopandas-feedstock/issues/64 。但是，它是从2019年开始，并且在问题解决之前就已经关闭，因此对我没有帮助。

Answer 1

我将提供与GitHub问题相同的建议，哪个Conda Forge具有在其文档中：不要混合通道。频道混合是所有动态库问题的最常见原因。

Conda Forge仅

使用YAML

“> so-fiona.yaml

name: so-fiona
channels:
  - conda-forge
dependencies:
  - python=3.9
  - fiona
  - salem

和conda env create -f so-fiona.yaml，在所有主要平台上都可以正常工作。
