为什么conda创建尝试安装奇怪的包？

Question

我正在尝试安装一个与我的其他环境完全分离的新conda环境,所以我运行:

conda create --name foot35 python=3.5

然后Anaconda要求我批准安装这些新包:

我不知道为什么它会暗示这些特定的.我查了一下lockfile,它的网站说:

注意:不推荐使用此包.

以下是我的命令提示符的屏幕截图作为附加信息.

我正在尝试进行与根环境无关/独立的全新安装.

为什么conda试图安装这些东西,我该如何解决？

Answer 1

conda create将"从指定包列表中创建一个新的conda环境." (https://conda.io/docs/commands/conda-create.html)

什么列表??!？.condarc文件是conda配置文件.

https://conda.io/docs/user-guide/configuration/use-condarc.html#overview

The .condarc file can change many parameters, including:

Where conda looks for packages.
If and how conda uses a proxy server.
Where conda lists known environments.
Whether to update the bash prompt with the current activated environment name.
Whether user-built packages should be uploaded to Anaconda.org.
**Default packages or features to include in new environments.**

Additionally, if you ever typed conda config, even accidentally...

The .condarc file is not included by default, but it is automatically created in your home directory the first time you run the conda config command.

A .condarc file may also be located in the root environment, in which case it overrides any in the home directory.

如果您想要一个简洁的环境,那么Boshika建议实例的--no-default-packages标志,您可以检查并修改所有其他环境的默认包.(https://conda.io/docs/user-guide/configuration/use-condarc.html#always-add-packages-by-default-create-default-packages)

Always add packages by default (create_default_packages)
When creating new environments, add the specified packages by default. The default packages are installed in every environment you create. You can override this option at the command prompt with the --no-default-packages flag. The default is to not include any packages.

EXAMPLE:

create_default_packages:
  - pip
  - ipython
  - scipy=0.15.0

由于所有操作系统的遗留要求,Lockfile可能存在.希望您有选择删除它的工具.

为了避免 conda 安装所有默认包，你可以试试这个

 conda create --name foot35 --no-deps python=3.5
