我试遍了网上所有关于这个问题的解决方案，还尝试了换源，也卸载重装了conda，但是都不好用。
 最后！我发现我的网络代理在开着！！！关了就好了。
 大家可以看看自己的网络代理有没有开，有就关掉好了。或者参照一下大神们的博客设置一下代理，不过我不会，我就直接简单粗暴的把他关掉。

				Anyone at the executive level deals with a plethora of questions and concerns that would make any normal person's head swim. However, those at the C-level cannot afford that, and so they seek answers as a means of ensuring that all is well within the organization. This tactic works until they look at IT. Getting a good, solid answer to the question, "Are we getting a good return on our investment in IT?" is never easy, direct, or straightforward even for many IT managers. Trust us: this situation is commonplace in every industry. Given that a company's IT spend is, next to salary and benefits, the biggest item in the budget, it's almost mindboggling that accountability in this mission critical is so hard to come by. Executives care about the value IT components represent. They long to understand in a concrete manner how IT provides value through cost reductions, new revenue streams, growth opportunities, and compliance.
				使用Create React App，Docker（和Nginx）的运行时环境变量
该存储库显示了如何实现运行时环境变量。 与传统解决方案不同，这允许您通过环境变量配置React应用程序，而无需再次构建。
 该存储库在Medium博客文章中进行了深入说明：
 有多种方法可以配置您的React应用程序，在这篇文章中，我将向您展示尊重，这意味着它会在运行时强制进行重新配置，因此不需要按环境构建。
 :thinking_face: 我们要实现什么？
 我们希望能够将我们的React应用程序作为Docker容器运行，该容器一次构建即可在任何地方运行。 我们想在运行时重新配置容器。 **输出应该是轻量级且高性能的容器，该容器可以将我们的React应用程序用作静态内容，这是通过使用Ngnix Alpine实现的。 我们的应用程序应允许在docker-compose文件中进行配置，例如：
 version: "3.2"

				一、创造一个虚拟环境报错**：**
An unexpected error has occurred. Conda has prepared the above report.

					(base) C:\Users\86183>conda install -c conda-forge opencv Collecting package metadata (current_repodata.json): done Solving environment: failed with current_repodata.json, will retry with next repodata source. Initial quick solve with frozen env failed.  Unfreezing env and trying again. Solving environment: failed with current_repodata.json, will retry with next repodata source. Collecting package metadata (repodata.json):这是什么意思
				这段代码是使用conda安装opencv时的命令行输出信息。其中，“Collecting package metadata”表示正在收集软件包的元数据；“Solving environment”表示正在解决软件包之间的依赖关系；“failed with current_repodata.json, will retry with next repodata source”表示解决依赖关系时出现了错误，conda将尝试使用其他的数据源进行解决。最后一句话“Collecting package metadata (repodata.json)”表示conda正在收集软件包的元数据。
