对于Cygwin的默认安装，PATH设置为/ etc / profile。您可以修改PATH，使/ usr / local / bin：/ usr / bin附加，而不是附加。

For a default installation of Cygwin, PATH is set is /etc/profile. You can modify PATH so that /usr/local/bin:/usr/bin are appended rather than prepended.

# PATH="/usr/local/bin:/usr/bin:${PATH}"
PATH="${PATH}:/usr/local/bin:/usr/bin/"
