[toc] ## Anaconda環境安裝問題 ### 問題1：current_repodata.json找不到 新建conda環境報錯 ``` 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."))')) ``` 經排查，確認沒有這個文件。正確的文件名為：`repodata.json`。  那么，**current_repodata.json**這個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 ``` #### 解決方案 把路徑“*Anaconda3/Library/bin*“目錄下的**libcrypto-1\_1-x64.dll**和**libssl-1\_1-x64.dll**拷貝到“*Anaconda3/DLLs*”目錄下即可。 ### 問題2：ssl模塊不可用 網絡問題 ``` 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: - 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=\'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."))')) ``` ``` #首先先添加清華的鏡像源 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，刪除`-defaults`。 ``` ## windows下： Anaconda3\pkgs\conda-4.7.12-py37_0\info\test\tests\condarc ``` 修改channels為： ``` 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 ``` > [參考內容](https://blog.csdn.net/ada0915/article/details/78529877)
