Conda 的 requirements.txt 没有正确安装

Question

我有一个安装了某些库的 python 环境 (env_1)，并使用以下命令创建了一个 requirements.txt：

conda list --export > requirements.txt

requirements.txt 文件中包含以下依赖项：

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

然后我使用coda deactivate 退出环境并尝试使用以下命令在requirements.txt 文件中创建一个新环境（test_env）：

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

但是这个报告和错误说：

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
