昨天帮同事解决问题，在装airtest的过程中，老是不成功。

使用的环境为conda，操作系统为win10-64bit的。

由于中间有过很多次修改，已记不清channels被改成啥样了。

解决问题的步骤如下：

1查看conda信息：

C:\Users\dell>conda info
Current conda install:

               platform : win-64
          conda version : 4.3.30
       conda is private : False

C:\Users\dell>conda config --remove channels "https://conda.anaconda.org/'https://mirrors.tuna.tsinghua.edu.cn/anaconda/cloud/conda-forge/'/win-64"

CondaKeyError: 'channels': "https://conda.anaconda.org/'https://mirrors.tuna.tsinghua.edu.cn/anaconda/cloud/conda-forge/'/win-64" is not in the 'channels' key of the config file

通过查看channels URL发现有些地址不正常。于是想能不删掉错误的地址。

2列出已有的channel

C:\Users\dell>conda config --get channels
--add channels 'defaults'   # lowest priority
--add channels "'https://mirrors.tuna.tsinghua.edu.cn/anaconda/pkgs/free/'"
--add channels "'https://mirrors.tuna.tsinghua.edu.cn/anaconda/cloud/conda-forge/'"
--add channels 'https://mirrors.tuna.tsinghua.edu.cn/anaconda/pkgs/free/'
--add channels 'https://mirrors.tuna.tsinghua.edu.cn/anaconda/pkgs/main/'
--add channels 'https://mirrors.tuna.tsinghua.edu.cn/anaconda/cloud/pytorch/'   # highest priority

3 删除错误的channel

C:\Users\dell>conda config --remove channels "'https://mirrors.tuna.tsinghua.edu.cn/anaconda/pkgs/free/'"

C:\Users\dell>conda config --remove channels  "'https://mirrors.tuna.tsinghua.edu.cn/anaconda/cloud/conda-forge/'"

4 再次查看channel，发现已经正常

C:\Users\dell>conda config --get channels
--add channels 'defaults'   # lowest priority
--add channels 'https://mirrors.tuna.tsinghua.edu.cn/anaconda/pkgs/free/'
--add channels 'https://mirrors.tuna.tsinghua.edu.cn/anaconda/pkgs/main/'
--add channels 'https://mirrors.tuna.tsinghua.edu.cn/anaconda/cloud/pytorch/'   # highest priority

5 查看info，发现已经正常

6升级pip

python -m pip install --upgrade pip

猜测airtest安装不成功和pip的版本有关系

7再次安装airtest, 成功

总结

包安装不成功，大概和如下因素有关：

1. conda 源有问题；

2. pip 版本太低

通过这个过程，我们同时掌握了channels的查看、添加和删除技巧；

附conda环境迁移技巧：

anaconda快速下载方法：

wget --user-agent="Mozilla" https://mirrors.tuna.tsinghua.edu.cn/anaconda/archive/Anaconda3-2024.02-1-Linux-x86_64.sh

要在不同机器之间迁移conda环境，可以使用以下步骤：

1. 在源机器上激活并导出环境：

   ​​​​​​​conda activate myenv
   conda env export > environment.yml

   这会在当前目录下创建一个environment.yml文件，其中包含了当前环境的所有依赖关系。

    

2. 将environment.yml文件复制到目标机器上。

3. 在目标机器上使用以下命令来创建一个新环境：

   conda env create -f environment.yml

   这会在目标机器上创建一个与源机器上的环境相同的环境。

注意： 

• 如果目标机器上已经有了相同名称的环境，它会被覆盖。

• 如果有特定于操作系统的依赖关系或路径，可能需要在不同机器上调整environment.yml文件。

• 如果目标机器上缺少某些包，可能需要手动安装或者修改environment.yml文件来指定适合目标机器的包版本。
