Even though I already have it installed, I can't use it by typing python3
. 即使我已经安装了它,我也不能通过输入python3
来使用它。 How do I solve this? 我该如何解决这个问题? I want to remove 3.6.2 and have python3
map to 3.6.4. 我想删除3.6.2并将python3
映射到3.6.4。
As your python3
is not linked to homebrew one, you should let homebrew force relink python3
: 由于你的python3
没有链接到自制的,你应该让homebrew force重新链接python3
:
rm /usr/local/bin/python3
brew unlink python3; brew link --overwrite python3
link of python3
on my machine is: 我机器上python3
链接是:
/usr/local/bin/python3 -> ../Cellar/python3/3.6.4/bin/python3
更新终端中的python run brew update
(这将更新Homebrew)然后brew upgrade python3
最后你可以运行brew cleanup python3
来删除旧版本
