无法使用bash脚本中的nvm

Question

我正在尝试编写一个shell脚本来自动化我的开发环境设置(安装python,nvm,node,mongo等...).我正在使用nvm来安装Node.它会告诉您关闭并重新打开终端以开始使用nmv命令.我尝试使用.bashrc和.profile来使命令立即可用,因此我可以继续使用nvm install运行脚本,但它不起作用.

以下是与安装NVM/Node相关的脚本部分:

#install nvm and latest node version
# sourcing profile and bashrc is not working here. nvm does not execute the next two lines to install node.

wget -qO- https://raw.githubusercontent.com/creationix/nvm/v0.30.2/install.sh | bash
source ~/.profile
source ~/.bashrc
nvm install 5.0
nvm alias default node

我收到这些消息,但请注意我已经运行了脚本并且NVM/Node已经安装并正常工作.我也可以在同一个终端中使用nvm和node,在完成后运行脚本.它只是在脚本中不起作用.

=> Downloading nvm from git to '/home/myDir/.nvm'
=> fatal: destination path '/home/myDir/.nvm' already exists and is not an empty directory.
fatal: Not a git repository (or any of the parent directories): .git
fatal: Not a git repository (or any of the parent directories): .git

=> Source string already in /home/myDir/.bashrc
=> Close and reopen your terminal to start using nvm
./install-programs.sh: line 27: nvm: command not found
./install-programs.sh: line 28: nvm: command not found

Answer 1

如果您在主 shell 上运行 nvm，您只需要添加：

export NVM_DIR=$HOME/.nvm;
source $NVM_DIR/nvm.sh;

在你的脚本中

Answer 2

只需将其放在脚本之上即可：

export NVM_DIR="$HOME/.nvm"
[ -s "$NVM_DIR/nvm.sh" ] && \. "$NVM_DIR/nvm.sh"  # This loads nvm
[ -s "$NVM_DIR/bash_completion" ] && \. "$NVM_DIR/bash_completion"  # This loads nvm bash_completion

在这里工作就像一个魅力。

Answer 3

这对我有用.

首先使用SSH或控制台安装nvm(一次和单独):

$ wget -qO- https://raw.githubusercontent.com/creationix/nvm/v0.30.2/install.sh | bash

然后在您的脚本中加载您的配置文件,如下所示:

. ~/.nvm/nvm.sh
. ~/.profile
. ~/.bashrc

并且有一些运气nvm应该在脚本中可用.

nvm install 4.4.2
