nvm use message not formatted properly and saying a version I have installed is not.

• How did you install nvm? (e.g. install script in readme, homebrew):
  I installed it via curl -o- https://raw.githubusercontent.com/creationix/nvm/v0.33.2/install.sh | bash

• What steps did you perform?

While using node 7.3, I navigated to my project directory with the following .nvmrc file:

xueye$ cat .nvmrc
v7.9.0

I proceeded to type nvm use which failed. I then tried nvm install which failed.

• What happened?

I got the following message:

xueye$ nvm use
>ound '/Users/xueye/Work/proj/.nvmrc' with version <v7.9.0
" is not yet installed

xueye$ nvm install
>ound '/Users/xueye/Work/proj/.nvmrc' with version <v7.9.0
' not found - try `nvm ls-remote` to browse available versions.

• What did you expect to happen?

I expected nvm to switch node the 7.9.0

• Is there anything in any of your profile files (.bashrc, .bash_profile, .zshrc, etc) that modifies the PATH?

My ~/.bash_profile is:

xueye$ cat ~/.bash_profile

[[ -s "$HOME/.profile" ]] && source "$HOME/.profile" # Load the default .profile

[[ -s "$HOME/.rvm/scripts/rvm" ]] && source "$HOME/.rvm/scripts/rvm" # Load RVM into a shell session *as a function*

export PATH="$HOME/.node/bin:$PATH"
export PATH="/usr/local/mysql/bin:$PATH"
source ~/.bashrc

export PATH=/Users/xueye/Library/Android/sdk/tools:$PATH
export PATH=/Users/xueye/Library/Android/sdk/platform-tools:$PATH
export PATH="/usr/local/sbin:$PATH"
alias cf='/Users/xueye/.cfscript'

if [ -f $(brew --prefix)/etc/bash_completion ]; then
  source $(brew --prefix)/etc/bash_completion
fi

My .bashrc is:

xueye$ cat ~/.bashrc
export PATH="$PATH:$HOME/.rvm/bin" # Add RVM to PATH for scripting
NPM_PACKAGES="${HOME}/.npm-packages"

# Unset manpath so we can inherit from /etc/manpath via the `manpath` command
unset MANPATH # delete if you already modified MANPATH elsewhere in your config
export MANPATH="$NPM_PACKAGES/share/man:$(manpath)"
NODE_PATH="$NPM_PACKAGES/lib/node_modules:$NODE_PATH"

PATH="$NPM_PACKAGES/bin:$PATH"

eval `ssh-agent`
ssh-add ~/.ssh/id_rsa

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

export PATH="$HOME/.yarn/bin:$PATH"
[ -s "$NVM_DIR/bash_completion" ] && \. "$NVM_DIR/bash_completion"  # This loads nvm bash_completion

Thanks!

You appear to have a trailing newline in .nvmrc - what happens if you eliminate that?

[philbarresi]

Good catch on the newline. If I eliminate that, I get:

xueye$ nvm use
>ound '/Users/xueye/Work/proj/.nvmrc' with version <v7.9.0
 -> N/A" is not yet installed.

xueye$ nvm install
>ound '/Users/xueye/Work/proj/.nvmrc' with version <v7.9.0
' not found - try `nvm ls-remote` to browse available versions.

[ljharb]

hmm, the output is definitely messed up (the > that should be on the end of the line is showing up at the beginning).

Any chance you have command or printf aliased to anything?

[philbarresi]

I just checked, and no, they're normal.

[ljharb]

@philbarresi thanks for bearing with me. does nvm_rc_version print out the same thing?

If so, what about read -r NVM_RC_VERSION < "/Users/xueye/Work/proj/.nvmrc" ; echo "$?|$NVM_RC_VERSION"?

[philbarresi]

No problem! Thanks for all the support!

xueye$ nvm_rc_version
>ound '/Users/xueye/Work/proj/.nvmrc' with version <7.9

xueye$ read -r NVM_RC_VERSION < "/Users/xueye/Work/proj/.nvmrc" ; echo "$?|$NVM_RC_VERSION"
0|7.9

[ljharb]

ok, so basically the only command being ran there between the read and the nvm_rc_version output is nvm_echo "Found '${NVMRC_PATH}' with version <${NVM_RC_VERSION}>".

Can you run that command and provide the output (assuming $NVM_RC_VERSION is set to 7.9 and $NVMRC_PATH is set to /Users/xueye/Work/proj/.nvmrc), and then if that's still got the misplaced >, provide the full output of type nvm_echo?

[ljharb]

@philbarresi any chance you could provide this output?

[MichaelPaulukonis]

I also had a trailing newline in my .nvmrc file, as per https://github.com/creationix/nvm#nvmrc

The contents of a .nvmrc file must be the (as described by nvm --help) followed by a newline. No trailing spaces are allowed, and the trailing newline is required.

However, we were receiving the following message:

```A: version "8.10.0
-> N/A" is not yet installed.

`8.10.0` is definitely installed, as `nvm ls` output demonstrated (also, .nvrcm output below):

```        v6.10.3 *
->       v8.2.1 *
        v8.10.0 *
default -> 8.2.1 (-> v8.2.1 *)
node -> stable (-> v8.10.0 *) (default)
stable -> 8.10 (-> v8.10.0 *) (default)
iojs -> N/A (default)
lts/* -> lts/carbon (-> N/A)
lts/argon -> v4.9.1 (-> N/A)
lts/boron -> v6.14.1 (-> N/A)
lts/carbon -> v8.11.1 (-> N/A)
Found '[path/to/].nvmrc' with version <8.10.0
>

Note how the newline is included in the version.

When I removed the "required" trailing newline, nvm use worked perfectly.

NOTE: AFAIK we are not using CR/LF in our project; all dev is done on Mac OS and build is on Ubuntu.

[ljharb]

What prints out if you explicitly printf '|' && cat .nvmrc && printf '|'?

[MichaelPaulukonis]

SSH: EXEC: STDOUT/STDERR from command [cd pr/86 && printf '|' && cat .nvmrc && printf '|' && nvm use && npm install && chmod a+x ./wkhtmltopdf && npm run test:js] ...
|8.10.0
|Found '/home/jenkins/pr/86/.nvmrc' with version <8.10.0
>
N/A: version "8.10.0
 -> N/A" is not yet installed.

You need to run "nvm install 8.10.0
" to install it before using it.

The hexdump suggests only the newline (0A) is present:

  Offset: 00 01 02 03 04 05 06 07 08 09 0A 0B 0C 0D 0E 0F   
00000000: 38 2E 31 30 2E 30 0A                               8.10.0.

Again, Mac OS, build output above was run on an Ubuntu image, and editing (including hexdump) done in VS Code.

[ljharb]

interesting, thanks for the followup.

I think that since the documentation specifies it, what we need to do is alter the .nvmrc parsing so that it can handle trailing newlines. It's possible #1740 addresses this; are you able to update to the latest master and try there?

[MichaelPaulukonis]

Just noticed you asked me to try a new version; I'll try to get that done this week and let you know.

[MichaelPaulukonis]

I can confirm that v0.33.11 does not experience this issue.

With or without a trailing newline, nvm parses the .nvmrc file correctly for me.

[itwasmattgregg]

I'm on a mac and found this issue. Figured out the person who created the .nvmrc file was on a windows machine and the line endings are different there. Recreated the .nvmrc file on my mac and nvm use ran fine. Hope this helps others.
