为什么我不能从conda环境中更新conda，但是可以使用它？

Why I cannot update conda from a conda environment, but I can use it?

示例

我可以从 root

[ravas@localhost ~]$ source activate (base) [ravas@localhost ~]$ conda update conda Solving environment: done # All requested packages already installed.

我无法从 p36 更新它：

(base) [ravas@localhost ~]$ source activate p36 (p36) [ravas@localhost ~]$ conda update conda PackageNotInstalledError: Package is not installed in prefix. prefix: /home/ravas/miniconda3/envs/p36 package name: conda

这似乎是由于未在 p36

(base) [ravas@localhost ~]$ conda list | grep conda # packages in environment at /home/ravas/miniconda3: anaconda-client 1.7.1 py37_0 anaconda-navigator 1.9.2 py37_0 conda 4.5.11 py37_0 conda-env 2.6.0 1 (p36) [ravas@localhost ~]$ conda list | grep conda # packages in environment at /home/ravas/miniconda3/envs/p36: anaconda 5.3.0 py36_0 anaconda-client 1.7.2 py36_0 anaconda-project 0.8.2 py36_0 pdfminer.six 20170720 py36_0 conda-forg

但是，从 p36 我可以使用conda

However, from p36 I can use conda

(p36) [ravas@localhost ~]$ conda update anaconda Solving environment: done # All requested packages already installed.

为什么？

推荐答案

conda 未安装在新环境中。但是您可以在这样的派生环境中获得 conda ：

conda is not installed in the new environment. But you can get a conda in that derived environment like this:

• 激活基本环境
• 激活其他环境
• 运行 conda安装conda

• activate the base environment
• activate your other environment
• run a conda install conda

现在您在另一个环境中有一个 conda ，并且可以照常使用该环境。

Now you have a conda in that other environment, and work with that environment as usually.
