?Conda初始化

使用brew安装完miniconda后提示

==> Caveats
Please run the following to setup your shell:
  conda init "$(basename "${SHELL}")"

conda init zsh

之后cat ~/.zshrc可以看到conda initialize追加内容

此时每次运行zsh都会自动激活base环境

?禁止conda自动激活base环境

conda config --set auto_activate_base false

?查看当前conda设置

cat ~/.condarc

如果没有在init后对conda进行其他设置

默认情况下.condarc不存在

?查阅其他conda设置选项

conda config --describe

输出如下：

# # use_only_tar_bz2 (NoneType, bool)
# #   A boolean indicating that only .tar.bz2 conda packages should be

# remote_read_timeout_secs: 60.0

# # ssl_verify (bool, str)
# #   aliases: verify_ssl
# #   Conda verifies SSL certificates for HTTPS requests, just like a web

# #   dependencies, rather than raising an unsatisfiable error. With channel
# #   priority disabled, package version takes precedence, and the
# #   configured priority of channels is used only to break ties. In

# #   installing on a different filesystem than the one that the package
# #   cache is on. When allow_softlinks is False, conda still uses hard-
# #   links when possible, but when it is not possible, conda copies files.
# #   Individual packages can override this setting, specifying that certain
# #   files should never be soft-linked (see the no_link option in the build
# #   recipe documentation).
# #
# allow_softlinks: false

# # always_copy (bool)
# #   aliases: copy

# always_copy: false

# # always_softlink (bool)
# #   aliases: softlink
# #   Register a preference that files be soft-linked (symlinked) into a
# #   prefix during install rather than hard-linked. The link source is the
# #   'pkgs_dir' package cache from where the package is being linked.
# #   WARNING: Using this option can result in corruption of long-lived
# #   conda environments. Package caches are *caches*, which means there is
# #   some churn and invalidation. With this option, the contents of
# #   environments can be switched out (or erased) via operations on other
# #   environments.
# #
# always_softlink: false

# # path_conflict (PathConflict)
# #   The method by which conda handle's conflicting/overlapping paths
# #   during a create, install, or update operation. The value must be one

# #
# non_admin_enabled: true

# # separate_format_cache (bool)
# #   Treat .tar.bz2 files as different from .conda packages when filenames
# #   are otherwise similar. This defaults to False, so that your package
# #   cache doesn't churn when rolling out the new package format. If you'd
# #   rather not assume that a .tar.bz2 and .conda from the same place
# #   represent the same content, set this to True.
# #
# separate_format_cache: false

# # verify_threads (int)
# #   Threads to use when performing the transaction verification step.
