Nvm: unnecessary system node required to get past prefix error on clean install

[travi]

As mentioned in https://github.com/creationix/nvm/issues/1102#issuecomment-250951849, when running nvm install (after sourcing the nvm.sh script with the --no-use flag) from a project with an .nvmrc file, I'm running into the nvm is not compatible with the npm config "prefix" option: currently set to "" error on a clean image unless a system node is available.

For context, this is for a docker image to be used as a Jenkins agent for building node projects. However, to distill it down a bit more, this is an alpine linux docker image based on openjdk:8-jdk-alpine with minimal additional installations, mostly dependencies of being a Jenkins agent.

No .npmrc is being added outside of the project being built by Jenkins and the .npmrc for the project only contains save-exact=true. Environment variables are only being set for Jenkins specific config and $NVM_DIR.

As soon as nodejs is added to the busybox apk add list, nvm install completes successfully without the prefix error, but this system level node installation should be unnecessary since nvm should be responsible for making node and npm available to the Jenkins build.

To make matters worse, the prefix failure from the nvm install command exits with a zero status code, so further commands chained with && are successfully triggered but fail because npm was not made available. This certainly complicated tracking down the problem because the prefix error appeared to only be a warning. If the prefix error is enough to not make npm or node available, the nvm install command should not exit with 0.

nvm install should return zero when it installs correctly - but I can see the logic in that if nvm use fails, the whole command should exit nonzero. That's one bug that can be easily fixed.

I see that your docker image is running the install script - after this runs, can you manually check the appropriate profile files (that hopefully docker is using with a login shell) for the appropriate nvm lines, and let me know what you find?

[travi]

the image does not contain a profile file for the jenkins user that the build runs as. the warning suggesting manual addition is shown, but exits with a zero exit code. i think the zero exit is appropriate here since the message is more of a warning.

in our case, we set $NVM_DIR directly in the image and source the nvm.sh file (with the --no-use flag) as part of the build command at run time.

tl;dr: the lines are not added to a profile, but are handled (and work correctly when the nodejs package is included by apk)

Gotcha.

Can you get to a state where "nodejs" is not installed, and nvm use node fails with the prefix error, and provide the output of nvm debug and nvm use node --delete-prefix && nvm debug?

[travi]

I have not tracked down the output that you asked for, but wanted to share something else that I realized.

This should probably have been obvious, but since the nvm install command exits with zero and the next step continues, I assumed that the presence of the system node allowed nvm to get past the prefix error. This assumption was not correct. nvm still fails to make the desired version of node/npm available, but the next command continues, using that system node installation.

You may have recognized this, but it did confuse me. Beyond getting us on the right track for the issue at hand, it does further highlight the need for that exit code to be non-zero.

I'm still working on getting to a state where I can get the other output. Stay tuned for that.

I'm trying to parse this out of Jenkins output, so hopefully i grabbed all the right pieces from nvm debug, but output from that command is below:

[ljharb]

whoa, all the "none" lines are unexpected.

Also, why is $SHELL "/bin/false"?? Shouldn't it be bash, or sh, or something similar?

[travi]

for nvm use node --delete-prefix, i'm seeing the following:

Because alpine linux is so stripped down, it looks like it does not support the q flag for ls

But, then it doesn't seem to understand node for use:

You need to run "nvm install N/A" to install it before using it.

-q is part of posix - if alpine linux deviates from POSIX than nvm won't work on it.

If nvm_ls doesn't work because ls isn't working properly, then certainly it won't be able to resolve "node" to a specific version number :-/

[travi]

I've added the full output above for the nvm debug command in case it explains anything about the none lines or anything else. The lines w/o the +s are what I believe to be the actual output, but can't be sure if that is always the case.

[travi]

also added the full output for the nvm use node --delete-prefix build

[travi]

i was able to add the coreutils package to the alpine image to make a POSIX compliant ls available, but the other messages remain:

N/A: version "N/A" is not yet installed.
You need to run "nvm install N/A" to install it before using it.

[travi]

I saw that you asked about $SHELL. Jenkins does not use an interactive login shell, so that would not end up getting set. However, if you look at the first line of the full output, it uses /bin/bash to run the script that defines the build steps.

I think the question that I have that seems more related is "why is $PREFIX set to ''"?

[ljharb]

Yes, that's a good question. If you env | grep -i prefix, what shows up?

[travi]

prefix is not in the env output at all

[ljharb]

ok, what does nvm version node and set -x ; nvm use node print out?

[travi]

nvm version node = N/A

set -x ; nvm use node:

[travi]

any further thoughts from the latest output above?

[ljharb]

Yes - it looks like [' -d /home/jenkins/.nvm/versions/node ']' is failing, which indicates that there's no node versions installed. If you cd $NVM_DIR, is there a "versions" directory? if so, what's inside it?

keep in mind that each time I run these commands, it creates a new container instance, so previous commands have not had any effect. which command would you expect to create these directories?

[ljharb]

Sorry for the miscommunication. nvm install node should create them. I'm looking for the output of nvm install node ; nvm version node ; set -x ; nvm use node

[travi]

Theres a lot here, so hopefully some of it will be helpful (too long to include directly in the comment, so included as a file):

output.txt

[ljharb]

ok so…
the original prefix error might be related to:

++ npm config get prefix
/usr/bin/env: ‘node’: No such file or directory

which is here. the $PATH should allow node to be found, which should be set here. However, scrolling up in the output a bit, I see:

++ type npm
+++ npm --version
++ command printf ' (npm v)'
++ printf ' (npm v)'
+ NVM_USE_OUTPUT='Now using node v6.7.0 (npm v)'

… in other words, npm was present, but npm --version printed out an empty string (this is weird).

---

nvm version node worked fine, printing out v6.7.0 - which indicates that it was successfully installed (even though the implicit nvm use command had failed due to a failure in nvm_die_on_prefix, described above).

---

now for set -x ; nvm use node:
I see the same failure(s) I described in the first section here.

+ PATH=/home/jenkins/.nvm/versions/node/v6.7.0/bin:/usr/lib/jvm/java-1.8.0-openjdk/bin:/usr/local/sbt/bin:/etc/alternatives/java_sdk_1.8.0/bin:/var/lib/jenkins/.rvm/gems/ruby-2.1.5/bin:/var/lib/jenkins/.rvm/gems/ruby-2.1.5@global/bin:/var/lib/jenkins/.rvm/rubies/ruby-2.1.5/bin:/var/lib/jenkins/.rvm/bin:/usr/local/share:/usr/local/bin:/sbin:/bin:/usr/sbin:/usr/bin
+ export PATH

^ the above should ensure that /home/jenkins/.nvm/versions/node/v6.7.0/bin is checked first, and if you cd into that directory (in a container that has had nvm install node ran, ofc), you should see both node and npm in there. If so, can you run set +x; ls; which npm; ./npm --version and provide the output?

[travi]

+ ls /home/jenkins/.nvm/versions/node/v6.7.0/bin
node
npm
+ /home/jenkins/.nvm/versions/node/v6.7.0/bin/npm --version
/usr/bin/env: ‘node’: No such file or directory

it looks like since npm can't find node on the $PATH, it fails. i did not run the which command that you asked for because it is tough to get into that context from a jenkins script, but i would also expect it to fail since it doesn't look like the current directory is included in the path.

[travi]

i take it back, i was able to get the script to change directories successfully, but it confirmed that which npm failed.

[ljharb]

OK, If you then run PATH=/home/jenkins/.nvm/versions/node/v6.7.0/bin:$PATH npm --version, what happens?

[travi]

solved the issue, but by swapping an alpine linux base for a debian base.

the reason for the switch was due to digging into why npm --version and other npm commands kept failing with /usr/bin/env: ‘node’: No such file or directory.

$ head `which npm`
#!/usr/bin/env node

since npm sets a node shebang, it obviously needs to have node available. it would make sense for this to be as a result of node not being on the $PATH, which is why I agreed with the "weird"ness of the observations in the output above. however, it ended up not being a $PATH problem.

it turns out that node not being available was instead a result of symbols not being available to node:

+ ldd /home/jenkins/.nvm/versions/node/v6.7.0/bin/node

this is because alpine apparently uses musl as libc instead of the traditional glibc.

glibc can be installed on alpine, but starts to deviate from the reason we were using alpine in the first place. this, plus the fact that we were needing to install the more standard packages for things like coreutils, tar, make, g++, etc caused us to decide it simply made more sense to start with a debian base image.

while i'm moving away from using alpine, i think this effort did expose a couple of things that are worth influencing enhancements of nvm. the first is the exit code mentioned early on in the thread. the other would be a check for the presence of glibc rather than something else, like musl and failing early with a clear message, especially since the resulting failure doesn't show the absence of the necessary symbols without ldd.

[ljharb]

Thanks, that's very helpful! I'll leave this open until those have been investigated and/or addressed. Glad you got it working :-)

[travi]

Sure thing. Hopefully some of this will help the next guy at least :)

Thanks for the help along the way.

[ljharb]

Closing for now; will leave the "info" tag on it.
