Conda 拒绝执行 conda install flask-bootstrap。我有迷你康达。重新启动我的电脑没有帮助。我真的不知道还有什么相关的，但如果需要更多信息，我会在附近回复。我不知道在这里还能说什么，但是 stackexchange 需要我在这里添加更多细节。
我试过更新 conda 并将 conda 降级到 4.6.11。我在我的基础环境中尝试过，但它似乎也不起作用。

UnsatisfiableError: The following specifications were found
to be incompatible with the existing python installation in your environment:
- flask-bootstrap -> python[version='2.7.*,3.5.*,>=3.5,<3.6.0a0']
If python is on the left-most side of the chain, that's the version you've asked for.
When python appears to the right, that indicates that the thing on the left is somehow
not available for the python version you are constrained to. Your current python version
is (python=3.7). Note that conda will not change your python version to a different minor version
unless you explicitly specify that.
The following specifications were found to be incompatible with each other:
