python - 如何使用conda安装考拉？

Question

根据koalas docs ，使用 conda 安装 koalas 应该很简单

conda install koalas

但这会引发错误:

Collecting package metadata (repodata.json): done Solving environment: failed with initial frozen solve. Retrying with flexible solve.

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

• koalas

Current channels:

• https://conda.anaconda.org/anaconda-fusion/win-64
• https://conda.anaconda.org/anaconda-fusion/noarch
• https://repo.anaconda.com/pkgs/main/win-64
• https://repo.anaconda.com/pkgs/main/noarch
• https://repo.anaconda.com/pkgs/r/win-64

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

我尝试运行

conda install -c conda-forge pyspark

也是首先，而且效果似乎很好。但是 koalas 仍然会引发同样的错误。还有什么事情吗

Koalas requires PySpark so please make sure your PySpark is available.

比 conda install -c conda-forge pyspark 太明显而无法包含在文档中？

我还在虚拟环境中尝试了整个过程

conda create --name koalas-dev-env

如果这很重要的话。

系统信息:

Python 3.7.0
Anaconda 2019.10

Answer 1

正在运行

conda create -c conda-forge -n koalas-dev-env koalas pyspark

就可以了。由于您没有提供 conda-forge channel ，因此您遇到了问题。您还可以将后者添加到 .condarc 配置文件中。

正如OP所指出的，这应该在文档中明确说明。我做了一个pull request来解决这个问题。
