nvm在新的終端會話中保持“遺忘”節點

本文翻譯自：nvm keeps “forgetting” node in new terminal session

Upon using a new terminal session in OS X, nvm forgets the node version and defaults to nothing: 在OS X中使用新的終端會話時， nvm忘記節點版本並默認爲nvm ：

$ nvm ls : $ nvm ls ：

         .nvm
     v0.11.12
     v0.11.13

I have to keep hitting nvm use v.0.11.13 in every session: 我必須在每個會話中繼續nvm use v.0.11.13 ：

         .nvm
     v0.11.12
->   v0.11.13

I've tried both the brew install, as well as the official installation script. 我已經嘗試了brew安裝，以及官方安裝腳本。

My .profile for the brew version: 我的.profile爲brew版本：

#nvm
export NVM_DIR=~/.nvm
source $(brew --prefix nvm)/nvm.sh

And for the install.sh script: 對於install.sh腳本：

$ curl https://raw.githubusercontent.com/creationix/nvm/v0.10.0/install.sh | bash

#nvm
export NVM_DIR="/Users/farhad/.nvm"
[ -s "$NVM_DIR/nvm.sh" ] && . "$NVM_DIR/nvm.sh"  # This loads nvm

Any clue to what I'm doing wrong? 我有什麼不對的任何線索？

Try nvm alias default . 嘗試使用nvm alias default 。 For example: 例如：

$ nvm alias default 0.12.7

This sets the default node version in your shell. 這將在shell中設置默認節點版本。 Then verify that the change persists by closing the shell window, opening a new one, then: node --version 然後通過關閉shell窗口，打開一個新窗口，然後： node --version驗證更改是否仍然存在

nvm does its job by changing the PATH variable, so you need to make sure you aren't somehow changing your PATH to something else after sourcing the nvm.sh script. nvm通過更改PATH變量來完成它的工作，所以你需要確保在獲取nvm.sh腳本後你不會以某種方式將PATH更改爲其他東西。

In my case, nvm.sh was being called in .bashrc but then the PATH variable was getting updated in .bash_profile which caused my session to find the system node before the nvm node. 在我的例子中，在.bashrc中調用了nvm.sh，然後在.bash_profile中更新了PATH變量，導致我的會話在nvm節點之前找到了系統節點。

別名到node本身以避免更新默認別名以及稍後的節點版本更新。

nvm alias default node

The top rated solutions didn't seem to work for me. 最受好評的解決方案似乎對我不起作用。 My solution is below: 我的解決方案如下：

1. Uninstall nvm completely using homebrew: brew uninstall nvm 使用homebrew： brew uninstall nvm完全brew uninstall nvm
2. Reinstall brew install nvm 重新安裝brew install nvm

3. In Terminal, follow the steps below(these are also listed when installing nvm via homebrew): 在終端中，請按照以下步驟（通過自制軟件安裝nvm時也會列出這些步驟）：

   mkdir ~/.nvm cp $(brew --prefix nvm)/nvm-exec ~/.nvm/ export NVM_DIR=~/.nvm source $(brew --prefix nvm)/nvm.sh

The steps outlined above will add NVM's working directory to your $HOME path, copy nvm-exec to NVM's working directory and add to $HOME/.bashrc, $HOME/.zshrc, or your shell's equivalent configuration file.(again taken from whats listed on an NVM install using homebrew) 上面列出的步驟將NVM的工作目錄添加到$ HOME路徑，將nvm-exec複製到NVM的工作目錄並添加到$ HOME / .bashrc，$ HOME / .zshrc或shell的等效配置文件。（再次從什麼中獲取）在使用自制軟件的NVM安裝中列出）

This question has mentioned for the OSX, but it happened to me in my linux OS. 這個問題已經提到了OSX，但它發生在我的Linux操作系統中。 I tried using nvm alias default <version> but for each new terminal session the used node version was forgotten. 我嘗試使用nvm alias default <version>但是對於每個新的終端會話，忘記了使用的節點版本。 so, here is the solution that i figured out. 所以，這是我想出的解決方案。

make sure to set a default alias for node version ,put the following code in .bashrc, and source .bashrc . 確保爲節點版本設置默認別名 ，將以下代碼放在.bashrc中，並將source .bashrc代碼放在source .bashrc 。

export NVM_DIR="/home/bonnie/.nvm"
## If the file exists and is not empty
if [ -s "$NVM_DIR/nvm.sh" ]; then
    ## Source it
    source "$NVM_DIR/nvm.sh"
fi
NODE_DEFAULT_VERSION=$(<"$NVM_DIR/alias/default")
export PATH="$NVM_DIR/versions/node/$NODE_DEFAULT_VERSION/bin":$PATH
