conda 托管机器中 python 环境和包的问题

Question

我正在尝试学习 MongoEngine，MongoDB 来自 python Flask 环境

我有一个 python 3.8 环境，当我发出

conda install -c blaze flask-mongoengine

我收到一个错误：

Specifications:

flask-mongoengine -> python[version='2.7.|3.4.']

Your python: python=3.8

所以我尝试创建并激活 Python 3.4 环境：

conda create -n uav python=3.4 -c conda-forge
conda activate uav
(uav) bob@rja15 uav log % python --version
Python 3.4.5
(uav) bob@rja15 uav log % conda install -c blaze flask-mongoengine

但出现不同的错误：

Specifications:

flask-mongoengine -> python[version='>=2.7,<2.8.0a0|>=3.6,<3.7.0a0|>=3.7,<3.8.0a0|>=3.5,<3.6.0a0']

Your python: python=3.4

我迷路了。感谢您的帮助。

这似乎适用于 conda 4.8.3 和 mamba 0.4.3，Ubuntu 18.04。

我对flask-mongoengine一无所知，但食谱here似乎已经5年没有更新了，似乎不太受欢迎。

conda create -n tmp-db
conda activate tmp-db
mamba install flask-mongoengine
mamba install -c blaze flask-mongoengine
