r - 为什么 R "hashed"到 ${USER_HOME}/miniconda/bin/R？

Question

我不知道如何或为什么miniconda劫持了我的 R环境。我刚刚重装了R试图摆脱这种情况。但是R仍然指向miniconda版本:

$which R
/Users/steve/miniconda3/bin/R

所以我试图把它推开:

(base) 04:54:34/python $mv ~/miniconda3/bin/R ~/miniconda3/bin/R.miniconda

新版 R “似乎”现在是活跃的:

(base) 04:55:21/python $which R
/usr/local/bin/R
(base) 04:55:24/python $ll $(which R)
-rwxrwxr-x  1 root  admin  9156 Jun 23 16:48 /usr/local/bin/R

然而，当尝试实际运行时发生了一些有趣的事情 R :

$R
-bash: /Users/steve/miniconda3/bin/R: No such file or directory

我不明白为什么感动 R仍在引用中。 R 是否有某种别名或重定向？ ?

$type R
R is hashed (/Users/steve/miniconda3/bin/R)

这是在哪里定义的？我如何将其更改为正确的 /usr/local/bin/R ?

Answer 1

我发现“重定向”实际上是由于 which 的作用造成的.这个回答描述的情况https://stackoverflow.com/a/39009275/1056563

You probably needed to run hash -r in your session (or rehash if using zsh) to update your executables on PATH for the which command. A new terminal session would also fix the problem.
