Conda在pypi.org/simple上找不到软件包

Question

我通过conda安装软件包时遇到问题。它在简单的https://pypi.org频道中找不到任何包。

conda install logbook

返回：

PS C:\WINDOWS\system32> conda config --add channels 
https://pypi.org/simple
Warning: 'https://pypi.org/simple' already in 'channels' list, moving to the top
PS C:\WINDOWS\system32> conda install Logbook
Fetching package metadata ....
WARNING: The remote server could not find the noarch directory for the
requested channel with url: https://pypi.org/simple

It is possible you have given conda an invalid channel. Please double-check
your conda configuration using `conda config --show`.

If the requested url is in fact a valid conda channel, please request that the
channel administrator create `noarch/repodata.json` and associated
`noarch/repodata.json.bz2` files, even if `noarch/repodata.json` is empty.
$ mkdir noarch
$ echo '{}' > noarch/repodata.json
$ bzip2 -k noarch/repodata.json
...........

PackageNotFoundError: Packages missing in current channels:

  - logbook

We have searched for the packages in the following channels:

  - https://pypi.org/simple/win-64
  - https://pypi.org/simple/noarch
  - https://repo.continuum.io/pkgs/main/win-64
  - https://repo.continuum.io/pkgs/main/noarch
  - https://repo.continuum.io/pkgs/free/win-64
  - https://repo.continuum.io/pkgs/free/noarch
  - https://repo.continuum.io/pkgs/r/win-64
  - https://repo.continuum.io/pkgs/r/noarch
  - https://repo.continuum.io/pkgs/pro/win-64

  - https://repo.continuum.io/pkgs/msys2/win-64
  - https://repo.continuum.io/pkgs/msys2/noarch

我已经在浏览器中手动检查了日志模块是否在页面https://pypi.org/simple上的列表中。但是，似乎conda在https://pypi.org/simple/win-64中寻找软件包，但win-64目录不存在。

conda config --show表示，已配置的频道为https://pypi.org/simple

有什么建议吗？

conda通道必须具有特定的布局（win-64，win-32等），并且软件包必须以conda特定的方式构建（请参阅使用conda骨架构建conda软件包）。这些软件包通常针对特定的Python版本（尽管也应该有noarch软件包）和/或numpy版本针对不同的平台（Windows，Linux，Mac 32位或64位）构建。

您无法使用来直接从PyPI安装软件包，conda因为PyPI不符合conda-channel的资格，即使它是软件包，也无法像conda-packages那样构建。但是您可以使用pip（在conda中）安装它们。

但是：您可以检查所需的软件包是否在符合conda的渠道中分发（当前是一个非常受欢迎的渠道conda-forge）。乍看之下，几个渠道都包含一个logbook在蟒蛇云中命名的软件包（日志的搜索结果）。

如果您找到一个分发所需软件包版本的渠道（针对所需的Python版本和平台），则只需使用：

conda install -c channel_name logbook
