我使/ usr / local / world可写，是否安全？
我在使用Go（lang）框架Buffalo时遇到npm问题，框架无法通过“sudo”运行npm所以我需要使用chmod使npm世界可写。 我运行了以下命令
sudo chmod -R 777 /usr/local/ 现在我的Zshel给出了以下错误信息，可以吗？
zsh compinit: insecure directories, run compaudit for list. Ignore insecure directories and continue [y] or abort compinit [n]?
这是我的系统列表/ usr / local /

要修复/ usr / local /发出以下命令：
cd /usr/local/ chmod 755 * chmod 777 man cd /usr/local/lib/ chmod 775 * chmod g+s * chmod g+s python2.7/* chmod g+s python3.5/* cd /usr/local/share/ chmod 755 * chmod 775 emacs fonts sgml xml chmod g+s emacs fonts sgml xml chmod 775 emacs/* chmod g+s emacs/* chmod 775 sgml/* chmod g+s sgml/*
那应该是它。
- g + s设置SGID位（组粘）
- 775 = rwx rwx rx
- 755 = rwx rx rs
