git `autocrlf` setting causes syntax errors after install

[jesstelford]

I'm getting the following error when opening a new shell after installing nvm:

: command not found
: command not found
'ash: /Users/jtelford/.nvm/nvm.sh: line 12: syntax error near unexpected token `{
'ash: /Users/jtelford/.nvm/nvm.sh: line 12: `nvm_has() {

I successfully installed nvm with the following command:

$ curl https://raw.githubusercontent.com/creationix/nvm/v0.23.2/install.sh | bash

I am running OSX 10.10.1, and my shell is iTerm2 v2.0

Is there something I am doing wrong?

Thanks for your help :)

Can you gist your bash_profile and bash_rc contents?

[jesstelford]

Sure thing: .bash_profile

I don't have a .bashrc or .bash_rc.

[ljharb]

Hmm, that all looks normal. if you do . $NVM_DIR/nvm.sh on your normal command line, does it work?

[jesstelford]

Gives the same error:

$ . $HOME/.nvm/nvm.sh
: command not found
: command not found
'ash: /Users/jtelford/.nvm/nvm.sh: line 11: syntax error near unexpected token `{
'ash: /Users/jtelford/.nvm/nvm.sh: line 11: `nvm_has() {

[ljharb]

Very weird that the first character of the output is truncated. If you try it in the system Terminal app, the same?

[jesstelford]

Yeah, I noticed that too. It doesn't get truncated in Terminal.app, but still has the same error:

$ . $HOME/.nvm/nvm.sh
: command not found
: command not found
-bash: /Users/jtelford/.nvm/nvm.sh: line 11: syntax error near unexpected token '{
'bash: /Users/jtelford/.nvm/nvm.sh: line 11: `nvm_has() {

[ljharb]

OK, one other try - your install script used git to install nvm. Do you perhaps have any line ending settings in your ~/.gitconfig?

[jesstelford]

I do! ~/.gitconfig:

[core]
    autocrlf = true

[ljharb]

Mine is set to input. I wonder if perhaps "true" causes the wrong kind of line endings to show up?

If so, that's something that the install script should ideally handle.

Could you try setting yours to "input", delete $NVM_DIR and reinstall nvm?

[jesstelford]

Success! Removing those lines makes everything work. And re-instating the lines after nvm installation keeps everything working thereafter.

[ljharb]

Thanks for clarifying. I'm going to keep this issue open and rename it to deal with the autocrlf issue.
