conda virtual environment | install and list problems

1. conda creates a virtual environment. At this time, the conda list is empty, and the pip list is the native pip list

2.

conda install python=3.9

After that, the pip list is the same as the conda list, both of which are python and related dependencies

3.

conda install fake-useragent==0.1.11

Conda can install the packages that anaconda has (about a thousand), but some packages anaconda do not exist, take fake-useragent(0.1.11) as an example

If installed it will appear:

Collecting package metadata (current_repodata.json): doneSolving environment: failed with initial frozen solve. Retrying with flexible solve.Collecting package metadata (repodata.json): doneSolving environment: failed with initial frozen solve. Retrying with flexible solve.PackagesNotFoundError: The following packages are not available from current channels:- fake-useragent==0.1.11Current channels:- https://mirrors.tuna.tsinghua.edu.cn/anaconda/pkgs/main/win-64- https://mirrors.tuna.tsinghua.edu.cn/anaconda/pkgs/main/noarch- https://mirrors.tuna.tsinghua.edu.cn/anaconda/pkgs/r/win-64- https://mirrors.tuna.tsinghua.edu.cn/anaconda/pkgs/r/noarch- https://mirrors.tuna.tsinghua.edu.cn/anaconda/pkgs/msys2/win-64- https://mirrors.tuna.tsinghua.edu.cn/anaconda/pkgs/msys2/noarchTo search for alternate channels that may provide the conda package you'relooking for, navigate tohttps://anaconda.organd use the search bar at the top of the page.

So at this point we want to use pip install

pip install fake-useragent=0.1.11

pip install packages that are not available

After installation, open conda list and pip list

We will find that both lists are related to this package

The screenshot is as follows:

conda list: fake-useragent at the bottom

pip list: fake-useragent at the bottom

If the package is installed using conda install, it also exists in both lists

4. We import the package with pip install in this virtual environment, which can be successfully imported

Summary:

pip install can install packages that anaconda does not have. The packages appear in both lists and can be imported normally in the virtual environment.

In the conda virtual environment, pip list is indeed a proper subset of conda list.
