我遇到通过conda安装软件包的问题。它无法在通道https://pypi.org中找到任何包。
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:

We have searched for the packages in the following channels:

我已在浏览器中手动检查,日志模块位于第https://pypi.org/simple页的列表中。 好吧,似乎conda在https://pypi.org/simple/win-64中寻找包,但win-64目录在那里不存在。
conda config --show说,配置的频道是https://pypi.org/simple

有什么建议吗?

conda频道必须具有特定的布局(win-64,win-32,...),并且必须以conda特定的方式构建包(请参阅Building conda packages with conda skeleton)。这些包通常是针对特定的Python版本(尽管也应该有noarch包)和/或numpy版本以及不同的平台(windows,linux,mac 32bit或64bit)构建的。
您不能使用conda
直接从PyPI安装软件包,因为PyPI不符合conda-channel的条件,即使它是软件包,也不像conda-packages那样构建。但您可以使用pip
(在conda中)安装它们。
但是:您可以检查您想要的软件包是否在符合条件的频道中分发(一个非常受欢迎的频道目前是conda-forge
)。乍一看,几个通道在anaconda云中包含一个名为logbook
的包(search results for logbook)。
如果您找到一个分发所需软件包版本的渠道(以及所需的Python版本和平台),那么只需使用:
conda install -c channel_name logbook

Gohlke页面上有许多适用于Windows的Python产品。
假设你在自己的环境中安装了64位Py3.6,称为Py36,你可以这样做。
从Gohlke下载Logbook-1.1.0-cp36-cp36m-win_amd64.whl(或者您需要的任何版本)。
然后在命令提示符下:
activate
您要安装Logbook的conda环境。pip
安装您在该环境中下载的whl
。C:\scratch>activate Py36
(Py36) C:\scratch>pip install Logbook-1.1.0-cp36-cp36m-win_amd64.whl
Processing c:\scratch\logbook-1.1.0-cp36-cp36m-win_amd64.whl
