在Conda虚拟环境中运行PIP时有关未解析依赖项的错误消息

Question

我在Manjaro stable上运行一个zsh shell，其中Conda（4.10.1）虚拟环境由Python3.9.2激活，当我试图通过pip install安装一个包时，它有时会返回一条关于未解析依赖项的错误消息。例如，当我尝试安装Tensorflow时：

ERROR: pip's dependency resolver does not currently take into account all the packages that are installed. This behaviour is the source of the following dependency conflicts.
pyxnat 1.4 requires future>=0.16, which is not installed.
nipype 1.6.0 requires filelock>=3.0.0, which is not installed.

我使用conda install pip和which pip返回值安装了pip：

/home/gova/anaconda3/envs/drmdef/bin/pip

当我试图通过shell导入Tensorflow时，我得到了这样的回应：

Python 3.9.2 | packaged by conda-forge | (default, Feb 21 2021, 05:02:46) 
[GCC 9.3.0] on linux
Type "help", "copyright", "credits" or "license" for more information.
>>> import tensorflow

>>> 

这意味着TensorFlow确实已安装并可导入。这些错误消息不是问题，因为我还没有开始为TensorFlow配置系统。但任何与此相关的事情都会有所帮助

为什么我会看到错误消息？为什么pip不能解决所有未满足的依赖关系？ 如何解决此问题？
