[問題] Rmpi套件與TMPDIR environmental的問題

[ert5612p (胚胚尼)]

[問題] 下載Rmpi套件，時遇到終端機上「TMPDIR environmental」的問題
[問題類型]
 終端機指令上的問題
[軟體熟悉度]
使用者(有些Ｒ的作品)，但對終端機指令不了解

[問題敘述]
各位Ｒ專家們好，我是一個目前正在Mac上弄平行運算(讓R可以多核心運行)，卻在過程中
遇到許多麻煩的人～
我是參考 http://www.stats.uwo.ca/faculty/yu/Rmpi/mac_os_x.htm 文章一步一步下載
檔案
最後在R studio 中 install.packages(“Rmpi”)時出現了這樣一段話 ：

PMIx has detected a temporary directory name that results
in a path that is too long for the Unix domain socket:

    Temp dir: /var/folders/k5/qksw8vtj3yv2z1vzx2jlwy280000gn/T/openmpi-session
s-501@xiaopingguode-MacBook-Air_0/871

Try setting your TMPDIR environmental variable to point to
something shorter in length

聽我學長說，是指他說你環境變數太長，要下載到短一點了路徑（不知道對不對
但我不會打終端機的指令，想請問各位大大，我該打什麼在我的終端機才可以解決這問題
呢，希望可以手把手指引，謝謝各位><

It looks like orte_init failed for some reason; your parallel process is
likely to abort.  There are many reasons that a parallel process can
fail during orte_init; some of which are due to configuration or
environment problems.  This failure appears to be an internal failure;
here's some additional information (which may only be relevant to an
Open MPI developer):

  orte_ess_init failed
  --> Returned value Unable to start a daemon on the local node (-127) instead
 of ORTE_SUCCESS
