Conda 的 requirements.txt 没有正确安装

Question

I have a python environment (env_1) with certain libraries installed and create a requirements.txt using the following command:

conda list --export > requirements.txt

The requirements.txt file contains the following dependencies in it:

beautifulsoup4=4.9.3=pyhb0f4dca_0
numpy=1.15.4=py36h8b7e671_1001
pillow=8.0.0=py36h9a89aac_0
python=3.6.13=hdb3f193_0
sqlite=3.33.0=h62c20be_0
pandas==1.0.1=py36hb3f55d8_0

Then I came out of environment using coda deactivate and tried creating a new environment(test_env) with the dependencies in requirements.txt file using the below command:

conda create --name test_env  --file requirements.txt 

But this reported and error saying:

Collecting package metadata (current_repodata.json): done
Solving environment: failed with repodata from current_repodata.json, will retry with next repodata source.
Collecting package metadata (repodata.json): done
Solving environment: failed
