我一直在使用Homebrew并且在安装Python时发现了一个问题，可能是因为我首先从python的网站下载并安装了.pkg文件，然后运行{{1}由于某种原因，我发现它是＆＃34;正确的做法＆＃34;在Python的文档中。
现在brew install python命令正在按预期运行（重新启动我的mac后），但在尝试找到它无法正常工作的原因时，我找到了一个关于SO的答案，说要运行pip看看Homebrew本身是否有任何问题。还有。
我的问题是 - 有什么值得担心的吗？
如果是的话 - 任何人都可以帮我解决这些问题吗？在谷歌搜索解决方案给了我一些结果，但没有一个

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 what 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/3.5/bin/python3-config
/Library/Frameworks/Python.framework/Versions/3.5/bin/python3.5-config
/Library/Frameworks/Python.framework/Versions/3.5/bin/python3.5m-config

Warning: Python is installed at /Library/Frameworks/Python.framework
Homebrew only supports building against the System-provided Python or a
brewed Python. In particular, Pythons installed to /Library can interfere
with other software installs.
