[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>< #################################### ### 安裝時電腦給我的所有文字 #################################### 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 [xiaopingguode-MacBook-Air.local:97413] [[INVALID],INVALID] ORTE_ERROR_LOG: Un able to start a daemon on the local node in file ess_singleton_module.c at lin e 582 [xiaopingguode-MacBook-Air.local:97413] [[INVALID],INVALID] ORTE_ERROR_LOG: Un able to start a daemon on the local node in file ess_singleton_module.c at lin e 166 -------------------------------------------------------------------------- It looks like orte_init failed for some reason; your parallel process is likely to abort.
