當我從一個shell腳本中運行NVM，它似乎並沒有影響調用shell的環境：如何讓nvm在腳本中運行影響調用shell的環境？
$ node -v
v4.1.1
$ env | grep -i node
MANPATH=/home/ubuntu/.nvm/versions/node/v4.1.1/share/man:/usr/local/rvm/rubies/ruby-2.2.1/share/man:/usr/local/man:/usr/local/share/man:/usr/share/man:/usr/local/rvm/man

Now using node v0.10.40 (npm v1.4.28)
default -> 0.10.40 (-> v0.10.40)

什麼我需要劇本里面的「測試」這樣做是「節點-v 「在運行」./test「後會給我0.10.40嗎？
請注意，如果我打開一個新的終端，並輸入「node -v」，則獲得0.10.40。但由於某些原因，在我執行「測試」腳本的shell中，我似乎被4.1.1所困。
