Anaconda 安装yaml

因为这次安装表现怪异，所以记录一下，备忘。

不成功的安装conda install yaml

建立一个环境，随便取名env_example，命令如下，

(env_example) C:\Users\space>conda install yaml
Collecting package metadata (current_repodata.json): done
Solving environment: done

## Package Plan ##

  environment location: d:\Anaconda3\envs\mx36

  added / updated specs:
    - yaml

The following packages will be downloaded:

    package                    |            build
    ---------------------------|-----------------
    openssl-1.1.1g             |       he774522_0         4.8 MB  defaults
    ------------------------------------------------------------
                                           Total:         4.8 MB

The following NEW packages will be INSTALLED:

  yaml               pkgs/main/win-64::yaml-0.1.7-hc54c509_2

The following packages will be UPDATED:

  ca-certificates    anaconda/pkgs/main::ca-certificates-2~ --> pkgs/main::ca-certificates-2020.1.1-0
  certifi            anaconda/pkgs/main::certifi-2019.9.11~ --> pkgs/main::certifi-2020.4.5.1-py36_0
  openssl            anaconda/pkgs/main::openssl-1.1.1d-he~ --> pkgs/main::openssl-1.1.1g-he774522_0

Proceed ([y]/n)?

('Connection broken: OSError("(10054, \'WSAECONNRESET\')")', OSError("(10054, 'WSAECONNRESET')"))

问题：

一连几次，都无法安装成功，貌似每次都卡在openssl-1.1.1g，因为我已经配置了使用tuna镜像，所以也不清楚是不是镜像上有没有这个文件。

单独安装openssl

既然openssl无法安装成功，单独安装试一下，(参考： https://anaconda.org/anaconda/openssl)
