如何用conda安装考拉？
How to install koalas with conda?
根据 koalas docs，用 conda 安装 koalas 应该和
一样简单
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:

我试过了运行
conda install -c conda-forge pyspark
首先也是如此，结果似乎还不错。但是 koalas 仍然会引发相同的错误。还有什么要
Koalas requires PySpark so please make sure your PySpark is available.
比 conda install -c conda-forge pyspark 太明显以至于无法包含在文档中？
我也在虚拟环境中用
尝试了整个过程
conda create --name koalas-dev-env
如果这很重要。
系统信息：
Python 3.7.0
Anaconda 2019.10
运行
conda create -c conda-forge -n koalas-dev-env koalas pyspark
会的。您 运行 有问题，因为您没有提供 conda-forge 频道。后者也可以添加到 .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。
