Miniconda3:在当前的win-32频道匹配问题中找不到软件包 [英] Miniconda3: No packages found in current win-32 channels matching issue

问题描述

我一直在遵循有关如何安装Miniconda3的指南，并使用该指南来安装不同的软件包，如 NumPy 和 SciPy .

I've been following a guide in how to install Miniconda3 and use that to install different packages as NumPy and SciPy.

但是，在安装Miniconda3并在PyCharm中打开了一个新项目之后，该指南告诉我应该写:

However, after installing Miniconda3 and opened a new project in PyCharm, the guide tells me that I should write:

conda install numpy

...返回了

Fetching package metadata: Could not connect to https://repo.continuum.io/pkgs/free/noarch/

Error: No packages found in current win-32 channels matching: numpy

You can search for this package on Binstar with

binstar search -t conda numpy

You may need to install the Binstar command line client with

conda install binstar

哪个选择让我尝试:

conda install binstar

...这给了我同样的错误(甚至包括最后一行选择让我尝试conda install binstar的错误).

...which gave me the same error (even including the last line opting me to try conda install binstar).

作为参考，我还尝试使用conda update conda来生成Error: No packages found in current win-32 channels matching: conda.

I also tried, as a reference, to use conda update conda which resulted in Error: No packages found in current win-32 channels matching: conda.

我在安装到PATH变量时添加了Miniconda.有人对此有任何线索吗?

I've added Miniconda when installing into my PATH variables. Does anybody have any clue regarding this?

我有32位系统，并且已经安装了Miniconda的32位版本.

I have 32 bit system, and I've installed the 32 bit version of Miniconda.

推荐答案

conda似乎无法访问软件包存储库，因此您可能存在连接问题(您的防火墙可能阻止了conda，或者您位于代理服务器的后面.

It looks like conda is not able to reach the package repository, so you likely have connection issues (your firewall might be blocking conda, or maybe you are behind a proxy).

以下是三种解决方法(如果无法解决网络问题):

Here are 3 workaround (if you cannot fix your network problem):

您可以从 continuum 网站安装 Anaconda .与Miniconda不同，它带有许多预安装的软件包，例如numpy和scipy.

You could install Anaconda from continuum website. Unlike Miniconda, it comes with a lot of pre-installed packages such as numpy and scipy.

您可以从 conda存储库中手动下载归档文件包，并使用以下方式安装它们:

You can manually download the archives package from the conda repository, and install them using:

conda install numpy.tar.bz2

您需要下载操作系统的存档.根据您选择的软件包，您可能会遇到依赖项问题...

You need to download the archive for your operating system. Depending on the package you chose, you may have issue with dependencies...

此网站 ¹ 提供了预安装的Windows软件包，相对容易安装:

This site¹ provides tons of pre-built package for Windows, which are relatively easy to install:

python -m pip install numpy.whl

您应该使用conda随附的python可执行文件(如果您的系统上没有多个python安装，应该不会有问题).

You should use the python executable that comes with conda (should not be an issue if you do not have multiple python installations on your system).
