Mac - 没有名为 'scipy' 的模块

Question

我已经尝试了所有方法，但无法使 Scipy 正常工作。

通过 Homebrew 安装 Scipy，似乎工作正常 - 但在尝试导入它时出现错误。卸载，通过pip3安装，没有区别。酿造篡改，酿造 link（Scipy 和 python 的未 link 桶被迫 links），没有进展。

运行在 macOS Mojave (10.14.6) 上。 Numpy、matplotlib 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，但是 Scipy 应该安装在 python3.7（我正在使用）中。请参阅下面的更多内容：

==> 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

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

Answer 1

好吧，不知何故无意中修复了它。我卸载并重新安装了 numpy 和 scipy 几次都无济于事。最后卸载了 numpy、scipy、matplotlib、ipython 和 jupyter，这样它就可以让我卸载 python。重新安装 python numpy 和 scipy 没有解决任何问题。然后，在运行

之后

pip3 install --user numpy scipy matplotlib ipython jupyter pandas sympy nose

我认为这做到了。 Scipy 和 numpy 现在显然安装在

scipy in ./Library/Python/3.7/lib/python/site-packages (1.3.1)
numpy>=1.13.3 in ./Library/Python/3.7/lib/python/site-packages (from scipy) (1.17.2)

而不是 usr/local/lib/Python3.7/site-packages 中 "pip3 install scipy" 正在安装它。

现在唯一奇怪的是 ./Library/Python/ 实际上只包含一个名为 2.7 而不是 3.7 的文件夹（没有隐藏文件夹）。我很奇怪，但是，嘿，它有效。
