我试图在我的macOS计算机(10.14.4)上安装Certbot来生成证书,但是像往常一样,一些Homebrew错误正在困扰您。
运行brew update
和brew install certbot
之后,我尝试了基于sudo certbot certonly -a manual -d example.com --email your@email.com
的命令,但得到了sudo: certbot: command not found
。我也尝试过brew upgrade
。
brew doctor
显示:
Warning: The following directories do not exist:
/usr/local/sbin
You should create these directories and change their ownership to your account.
sudo mkdir -p /usr/local/sbin
sudo chown -R $(whoami) /usr/local/sbin
Warning: You have unlinked kegs in your Cellar.
Leaving kegs unlinked can lead to build-trouble and cause brews that depend on
those kegs to fail to run properly once built. Run `brew link` on these:
python@2
python
brew link python
返回Linking /usr/local/Cellar/python/3.7.3... Error: Permission denied @ dir_s_mkdir - /usr/local/Frameworks
。
由于某种原因,看来我现在已经安装了2个版本的Python,并且在我知道需要之前,我不希望运行Homebrew建议的任何命令。 python --version
返回Python 2.7.10
。
我应该卸载我的Python之一吗?其中一个是系统版本还是在其他地方进行了第三次安装?我应该符号链接哪一个,如何使certbot命令起作用?预先感谢
答案 0 :(得分:1)
sudo mkdir /usr/local/Frameworks
sudo chmod 1777
然后
brew link python3
这将在Mac上安装python3 我不会卸载python 2.7,因为仍然有很多脚本依赖于python 2.7!
