## Anaconda环境安装问题
### 问题1：current_repodata.json找不到
新建conda环境报错
```
C:\Users\Lijx>conda create -n pytorch python=3.7
Collecting package metadata (current_repodata.json): failed
CondaHTTPError: HTTP 000 CONNECTION FAILED for url <https://mirrors.tuna.tsinghua.edu.cn/anaconda/pkgs/main/win-64/current_repodata.json>
Elapsed: -
An HTTP error occurred when trying to retrieve this URL.
HTTP errors are often intermittent, and a simple retry will get you on your way.
SSLError(MaxRetryError('HTTPSConnectionPool(host=\'mirrors.tuna.tsinghua.edu.cn\', port=443): Max retries exceeded with url: /anaconda/pkgs/main/win-64/current_repodata.json (Caused by SSLError("Can\'t connect to HTTPS URL because the SSL module is not available."))'))
```
经排查，确认没有这个文件。正确的文件名为：`repodata.json`。
那么，**current_repodata.json**这个文件究竟是配置在哪里的呢？
```
C:\Users\Lijx>conda config --show-sources
==> C:\Users\Lijx\.condarc <==
ssl_verify: True
channels:
- https://mirrors.tuna.tsinghua.edu.cn/anaconda/pkgs/main/
- https://mirrors.tuna.tsinghua.edu.cn/anaconda/pkgs/free/
- https://mirrors.tuna.tsinghua.edu.cn/anaconda/cloud/conda-forge/
- https://mirrors.tuna.tsinghua.edu.cn/anaconda/cloud/msys2/
show_channel_urls: True
```
#### 解决方案
把路径“*Anaconda3/Library/bin*“目录下的**libcrypto-1\_1-x64.dll**和**libssl-1\_1-x64.dll**拷贝到“*Anaconda3/DLLs*”目录下即可。
### 问题2：ssl模块不可用
网络问题
```
E:\AIStudy\code\Machine-Learning-for-OpenCV-Second-Edition>conda env create -f environment.yml
Collecting package metadata (repodata.json): failed
CondaHTTPError: HTTP 000 CONNECTION FAILED for url <https://conda.anaconda.org/conda-forge/win-64/repodata.json>
Elapsed: -

SSLError(MaxRetryError('HTTPSConnectionPool(host=\'conda.anaconda.org\', port=443): Max retries exceeded with url: /conda-forge/win-64/repodata.json (Caused by SSLError("Can\'t connect to HTTPS URL because the SSL module is not available."))'))
```
```
#首先先添加清华的镜像源
conda config --add channels https://mirrors.tuna.tsinghua.edu.cn/anaconda/cloud/msys2/
conda config --add channels https://mirrors.tuna.tsinghua.edu.cn/anaconda/cloud/conda-forge/
conda config --add channels https://mirrors.tuna.tsinghua.edu.cn/anaconda/pkgs/free/
conda config --set show_channel_urls yes
```
需要修改配置文件：condarc，删除`-defaults`。
```
## windows下：
Anaconda3\pkgs\conda-4.7.12-py37_0\info\test\tests\condarc
```
修改channels为：
```
channels:
- binstar_username
- http://some.custom/channel
- https://mirrors.tuna.tsinghua.edu.cn/anaconda/pkgs/free/
- https://mirrors.tuna.tsinghua.edu.cn/anaconda/cloud/conda-forge/
- https://mirrors.tuna.tsinghua.edu.cn/anaconda/cloud/msys2/
- https://nanomirrors.tuna.tsinghua.edu.cn/anaconda/cloud
- https://nanomirrors.tuna.tsinghua.edu.cn/anaconda/cloud/bioconda
- https://nanomirrors.tuna.tsinghua.edu.cn/anaconda/cloud/bioconda/conda
```
