numpy已与Anaconda一起安装，但我收到一个ImportError（DLL加载失败：找不到指定的模块）

Question

我正在使用Python 3.7的Anaconda发行版。在安装的软件包中，我有numpy、熊猫等。在PyCharm IDE中，我将项目解释器设置为使用Anaconda安装的python.exe的路径：C：\用户\my_user_name\AppData\本地\连续体\anaconda3\python.exe

但是，当我尝试运行一个简单的python脚本时：

import numpy as np
print(np.pi)

我得到一个错误：

ImportError: 
Importing the multiarray numpy extension module failed.  Most
likely you are trying to import a failed build of numpy.
If you're working with a numpy git repo, try `git clean -xdf` (removes all
files not under vershtml" target="_blank">ion control).  Otherwise reinstall numpy.

Original error was: DLL load failed: The specified module could not be found.

See the full error message below:

During handling of the above exception, another exception occurred:

我试过使用Anaconda Prompt卸载和重新安装numpy，其中包含：conda uninstall numpy，然后是：conda install numpy[我现在有numpy 1.15.4]。重新安装似乎“成功”（至少根据Anaconda Prompt），但是，我一直在PyCharm中收到错误。

奇怪的是，当我直接进入蟒蛇提示，并输入：

python
import numpy as np
print(np.pi)

我没有得到任何错误，我能够看到正确的结果打印出来。起初，我认为在使用PyCharm时，我可能会以某种方式指向不同的可执行文件，但是我检查了Anaconda提示符和Pycharm的Python控制台，使用了:

sys.executable

它们都显示相同的路径：

'C:\\Users\\my_user_name\\AppData\\Local\\Continuum\\anaconda3\\python.exe'

请注意，在PyCharm中，当我尝试运行一个没有导入任何库的脚本时，或者当导入的库就像sys或os一样时，脚本运行正常。但是，当我尝试运行任何其他涉及导入以某种方式依赖于numpy的库的脚本时，它也失败了（即我导入熊猫的脚本等）。这些相同的脚本在蟒蛇提示符中工作正常。

我在这里不知所措，任何帮助都将不胜感激！
