## 问题：[PackagesNotFoundError: The following packages are not available from current channels][PackagesNotFoundError_ The following packages are not available from current channels] ##

## 问题一： ##

因为要用到lifelines 包，在cmd中使用conda install lifelines ,显示如下错误：

**PackagesNotFoundError: The following packages are not available from current channels:**

**- lifelines**

**Current channels:**

**- https://conda.anaconda.org/derickl/win-64**  
**- https://conda.anaconda.org/derickl/noarch**  
**- https://repo.anaconda.com/pkgs/main/win-64**  
**- https://repo.anaconda.com/pkgs/main/noarch**  
**- https://repo.anaconda.com/pkgs/free/win-64**  
**- https://repo.anaconda.com/pkgs/free/noarch**  
**- https://repo.anaconda.com/pkgs/r/win-64**  
**- https://repo.anaconda.com/pkgs/r/noarch**  
**- https://repo.anaconda.com/pkgs/msys2/win-64**  
**- https://repo.anaconda.com/pkgs/msys2/noarch**

**To search for alternate channels that may provide the conda package you're**  
**looking for, navigate to**

**https://anaconda.org**

**and use the search bar at the top of the page.**

## 问题二： ##

UnavailableInvalidChannel: The channel is not accessible or is invalid.  
channel name: anaconda/pkgs/free  
channel url: https://mirrors.tuna.tsinghua.edu.cn/anaconda/pkgs/free  
error code: 404  
原因如下：![watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L3N1cnNlcnJy_size_16_color_FFFFFF_t_70][]

## 解决方法一： ##

添加 Anaconda Python 免费仓库：

conda config --add channels https://mirrors.tuna.tsinghua.edu.cn/anaconda/pkgs/free/
    conda config --set show_channel_urls yes

检查Anaconda的config:查看channel个数以及格式，显然觉得有一个是有问题的：

conda config --show

参照 conda config 说明，移除某些channel ：

conda config --remove channels 'https://mirrors.tuna.tsinghua.edu.cn/anaconda/pkgs/free/'

或者可以使用 下面命令换回默认源：

conda config --remove-key channels

不过还有简单粗暴地方法：

直接修改conda的配置，一般在当前用户路径下，比如C:\\Users\\Administrator\\.condarc.condarc具体内容如下：show\_channel\_urls: truechannels:

\- https://mirrors.tuna.tsinghua.edu.cn/anaconda/pkgs/free/

\- defaults  
现在清华镜像不能使用了，删除这个镜像，可以试一下下面的镜像：

[http://pypi.douban.com/simple/][http_pypi.douban.com_simple] 豆瓣镜像

[http://mirrors.aliyun.com/pypi/simple/][http_mirrors.aliyun.com_pypi_simple] 阿里镜像

## 解决方法二： ##

anaconda search -t conda X

X为要安装的包

conda install -c https://conda.anaconda.org/X-path  X

X为包的具体名称  
例：首先输入 **anaconda search -t conda lifelines,**这样子就会显示可用的版本 ，我的显示效果如下所示：

选择适合自己的版本，比如，我选择的就是conda-forge/lifelines,在命令行中输入：

**conda install -c https://conda.anaconda.org/conda-forge lifelines, 注意conda-forge和lifelines之间没有“/”。**
