Mas OS Big Sur更新-找不到Python3/conda/pip [英] Mas OS Big Sur update - Python3 / conda / pip not found

问题描述

很抱歉，如果这是一个愚蠢的问题.我经常使用python/jupyter，从Mac OS High Sierra更新到Big Sur后，它停止工作.我试图弄清楚为什么，但是我对命令行方面并不满意.

Sorry if this is a stupid question. I use python/jupyter a lot and it's stopped working after updating from Mac OS High Sierra to Big Sur. I'm trying to figure out why, but I'm not great with command line stuff.

问题.当我尝试python3，pip -v，conda等时，它说找不到命令". python似乎仍然可以运行，但是它是2.7，我知道我有3个(我可能有一些来自不整洁文件系统的版本).我想避免再次重新安装所有软件包和东西，因为我知道它仍然在那里，而且我已经做过几次了.

The problem. When I try python3, pip -v, conda, etc. it says "command not found". python still seems to run, but it's 2.7 and I know I had 3 (I probably had a few versions from untidy file systems). I want to avoid reinstalling all my packages and things again, because I know it's still there and I've done this a few times already.

一些线索.我知道此操作系统升级将我从bash转移到zsh.我试过只是用chsh -s /bin/zsh切换回bash，但它仍然显示未找到命令.我还注意到，操作系统更新在我的Mac HD中创建了Mac HD(位于系统/卷下方)，在第二个中，似乎仍然是我的python3/conda/pip/etc.文件夹.不知道这是否/如何重要.或者，这仅仅是路径问题.

Some clues. I know this OS upgrade moves me from bash to zsh. I've tried just switching back to bash with chsh -s /bin/zsh but it still says command not found. I also noticed the OS update creates a Mac HD (below System/Volumes) within my Mac HD, and in that second one seems to be still all my python3/conda/pip/etc. folders. Not sure if/how this matters. Or if this is just a path issue.

我只想让Jupyter在Mac上再次运行，而无需从方格重新安装我的所有无数软件包.任何帮助表示赞赏！

I just want to get Jupyter running again on my Mac without reinstalling all my myriad packages from square one. Any help appreciated!

推荐答案

经过艰苦的努力和研究，我终于找到了对我有用的东西.

After extreme toil and research, I finally found something that worked for me.

1. 找到Anaconda3的位置.对我来说，它在~/opt/anaconda3
中
2. 打开终端并输入source <location of anaconda3>/bin/activate，然后在下一行中输入
   ，输入conda init zsh
3. 关闭终端，然后重新打开.再次打开它时，您应该会看到一个前缀(base).

1. Find the location of your Anaconda3. For me it was in ~/opt/anaconda3
2. Open terminal and type source <location of anaconda3>/bin/activate and then
   in the next line, write conda init zsh
3. Close your terminal and open it again. You should see a prefix (base) when you open it again.

总而言之，对我来说

rko3 ~ % source opt/anaconda3/bin/activate
rko3 ~ % conda init zsh

让我知道这是否对您有用！

Let me know if this works for you!
