【问题描述】：
我已经尝试了所有方法，但无法让 Scipy 工作。
通过 Homebrew 安装 Scipy，似乎工作正常 - 但尝试导入时出现错误。 卸载，通过pip3安装，没有区别。 Brew 修改，brew link（Scipy AND python 的未链接小桶的强制链接），没有进展。
在 macOS Mojave (10.14.6) 上运行。 Numpy、matplotlib 等等都运行良好。我在这里错过了什么？
我安装了两个版本的 python，但 Scipy 应该安装在 python3.7（我正在使用）中。见下文：

==> Caveats
If you use system python (that comes - depending on the OS X version -
with older versions of numpy, scipy and matplotlib), you may need to
ensure that the brewed packages come earlier in Python's sys.path with:
mkdir -p /Users/au341374/Library/Python/2.7/lib/python/site-packages
echo 'import sys; sys.path.insert(1, "/usr/local/lib/python3.7/site-packages")' >> /Users/au341374/Library/Python/2.7/lib/python/site-packages/homebrew.pth

Please note that these warnings are just used to help the Homebrew maintainers
with debugging if you file an issue. If everything you use Homebrew for is
working fine: please don't worry or file an issue; just ignore this. Thanks!
Warning: "config" scripts exist outside your system or Homebrew directories.
`./configure` scripts often look for *-config scripts to determine if
software packages are installed, and which additional flags to use when
compiling and linking.
Having additional scripts in your path can confuse software installed via
Homebrew if the config script overrides a system or Homebrew-provided
script of the same name. We found the following "config" scripts:
/Library/Frameworks/Python.framework/Versions/3.7/bin/python3.7-config
/Library/Frameworks/Python.framework/Versions/3.7/bin/python3.7m-config
/Library/Frameworks/Python.framework/Versions/3.7/bin/python3-config

简单地说：ModuleNotFoundError: No module named 'scipy'
