問題描述

嘗試通過 Windows NT 上的 cygwin 界面使用 anaconda 設置環境，但失敗了.

Trying to set up environments with anaconda through the cygwin interface on Windows NT, and failing.

創建環境(conda create -n test_env)工作正常.但是 activate test_env 失敗.

Creating environments (conda create -n test_env) works fine. But activate test_env fails.

我嘗試用以下方法破解它:

I tried hacking it with:

export PATH=/cygdrive/c/users/nick/anaconda3/envs/test:$PATH

這修正了一些行為(which python 指向正確的 python).但是如果我然后執行conda install"命令，它會安裝到根 anaconda 目錄中，而不是環境中.也許導出是 bash 會話的本地導出，并且 conda 調用了不同版本的 PATH?有沒有辦法讓PATH全局修改?

This fixes some behavior (which python points to the right python). But if I then do a "conda install" command, it installs into the root anaconda directory, not the environment. Perhaps the export is local to the bash session, and conda calls a different version of PATH? There a way to make the modification of PATH global?

推薦答案

在與這個問題搏斗了一段時間后，我想我已經實現了一個合理可行的方法，將 Anaconda 的 python(和相關環境)集成到 Cygwin 中.假設您有 Cygwin 和 Anaconda 獨立工作，要從 Cygwin 訪問所有 Anaconda 工具，.bash_profile 中的以下設置似乎可以解決問題.(我只包含了那些與集成相關的 .bash_profile 部分......希望我不會無意中遺漏一些東西.)

After wrestling with the problem for quite some time, I think I've achieved a reasonable and workable method to integrate Anaconda's python (and associated environments) into Cygwin. Assuming you have both Cygwin and Anaconda working independently, to access all of the Anaconda tools from Cygwin, the following setup in .bash_profile seems to do the trick. (I have only included those portions of .bash_profile relevant to the integration... hoping I did not miss something inadvertently.)

這個設置基本上做了三件事.首先，用戶需要將目錄 $CONDA_BASE_DIR 顯式設置為 conda/anaconda/miniconda 基礎環境的安裝位置.其次，.bash_profile 中有一個功能，可以使用 shell 變量 $CONDA_DEFAULT_ENV 來跟蹤當前的 conda 環境.最后，我們定義一個別名 cyg-conda 和一個函數 cyg-activate 用作標準 conda 和 的替換命令>激活命令.請注意，變量名 $CONDA_DEFAULT_ENV 是特殊的，由實際的 conda 命令在內部使用.

This setup essentially does three things. First, the user needs to explicitly set the directory $CONDA_BASE_DIR to be the location where the base environment for conda/anaconda/miniconda was installed. Second, there is a functionality in .bash_profile to keep track of the current conda environment using a shell variable $CONDA_DEFAULT_ENV. And finally, we define an alias cyg-conda and a function cyg-activate to be used as replacement commands for the standard conda and activate commands. Please note that the variable name $CONDA_DEFAULT_ENV is special, and used internally by the actual conda command.

使用此設置，我可以像通常使用 conda 一樣使用 cyg-conda 和 cyg-activate 和activate 在 Anaconda 命令提示符處，同時使環境可用于我的 Cygwin bash shell.

Using this setup, I am able to use cyg-conda and cyg-activate in the same way I would typically use conda and activate at the Anaconda command prompt, while making the environments available to my Cygwin bash shell.

當然愿意接受改進等方面的建議.

Certainly open to suggestions for improvements, etc.
