pytest安装后使用pytest命令报错，各位人才给看看哪里有问题呀？
最新：问题已解决
原因：
pycharm中设置shell为cmd.exe，而cmd.exe中默认使用的是anaconda的解释器（也不清楚pytest的安装情况等，不咋用），而非我常用的单独的python解释器，所以报错
解决方法：
1.删除环境变量中Path里关于anaconda的信息
2.重启pycharm
3.在pycharm终端中执行pytest命令就可以执行了，注意pytest命令后需要写完整.py文件的路径
前提：
1.我电脑中有单独的python解释器，也有anaconda环境，二者都在环境变量path中配置了
2.一般我使用pycharm默认选的是单独的python解释器
3.我利用pycharm下载pytest后，单独的python解释器目录下已经有了pytest.py
4.在cmd中使用pytest --version报错，详细如下
pip show pytest执行可以看到pytest成功安装了

ImportError:
IMPORTANT: PLEASE READ THIS FOR ADVICE ON HOW TO SOLVE THIS ISSUE!
Importing the numpy c-extensions failed.
- Try uninstalling and reinstalling numpy.
- If you have already done that, then:
1. Check that you expected to use Python3.7 from "f:\anaconda32020.02\python.exe",
and that you have no directories in your PATH or PYTHONPATH that can
interfere with the Python and numpy version "1.18.1" you're trying to use.
2. If (1) looks fine, you can open a new issue at
https://github.com/numpy/numpy/issues. Please include details on:
- how you installed Python
- how you installed numpy
- your operating system
- whether or not you have multiple versions of Python installed
- if you built from source, your compiler versions and ideally a build log
- If you're working with a numpy git repository, try `git clean -xdf`
(removes all files not under version control) and rebuild numpy.
Note: this error has many possible causes, so please don't comment on
an existing issue about this - open a new one instead.
Original error was: DLL load failed: 找不到指定的模块。
