Conda - Silently installing a package
提问by activelearner
I am trying to automate the process of setting up a development environment with pandas package using conda.
我正在尝试使用 conda 自动化使用 pandas 包设置开发环境的过程。
I installed conda, created and activated a dev environment. When I tried to install a package as follows, I noticed that there was a prompt to which a user had to key in Y or N (Proceed ([y]/n)?) for the installation to proceed successfully.
我安装了 conda，创建并激活了一个开发环境。当我尝试按如下方式安装软件包时，我注意到有一个提示，用户必须键入 Y 或 N（Proceed ([y]/n)?）才能成功进行安装。

How can I override these prompts so that the installation takes place silently? I tried using the -f flag but it does not seem to be existing with the conda install command.
如何覆盖这些提示以便安装以静默方式进行？我尝试使用 -f 标志，但它似乎不存在于 conda install 命令中。
Thanks in advance!
提前致谢！

使用$conda install -y pandas并在没有任何提示的情况下安装（请参阅文档）。

I suggest not to pass the confirmation process.
我建议不要通过确认过程。
because it always has important info regarding this installation(which package will be updated and which dependency package will be installed and which package will be downgraded)
因为它总是有关于这个安装的重要信息（哪个包将被更新，哪个依赖包将被安装，哪个包将被降级）
I once corrupt my environment due to not notice the update some of the package and took a long time to figure out some package need to stay in a older version to make some other package run properly.And that confirmation details will always makes you informed and tell you where to debug once you corrupt your package environment after installation
我曾经因为没有注意到某些软件包的更新而损坏了我的环境，并且花了很长时间才弄清楚某些软件包需要保留在旧版本中才能使其他软件包正常运行。而且确认的详细信息将始终让您了解和安装后一旦损坏包环境，告诉您在哪里调试
Anyway, here is the solution. Just use -yflag :
无论如何，这是解决方案。只需使用-y标志：
conda install -y PACKAGE_NAME

# install into the "base" env
conda install flake8 --yes
Script Use
