Additional context

Hello.

last week, I had a surprise when deploying an app, our build is throwing:

> node-rdkafka@2.7.4 install /home/travis/es/src/.../node_modules/node-rdkafka
> node-gyp rebuild

We use travis and it's python version is 3.6.7, I've tested other version and it worked fine on all of them. Which is strange, as 3.6.* is technically supported by node-gyp.

May someone give some light on what can I do? Forcing the use of another python version is something I'll have to explain to our ops team, so I would rather leave it to a last resort

[felipebritor]

I ended up setting another version on travis' before-install script, which worked. But the bug remains for python v3.6.7. Is it an issue for node-gyp itself?

[karousn]

the version that use it here is for legacy python version, i guest 2.7.* . so i think will be better to update node-gyp version use it here to be able for as to install recent python version.

[sadvazha]

Had the same issue, i have solved it by setting a PYTHON env variable to PYTHON=/path/to/python2.7 for npm install. There was a problem with node-gyp

[redduck3]

Had the same issue, I found that the node-gyp version in package.json is locked to 3.X. Please upgrade node-gyp to support python3.

[sam-github]

Looked, this isn't related to the node-gyp version in the package.json, which is a dev dep (not install dep), so the fact that it is v3.x isn't related.

gyp ERR! node-gyp -v v5.0.5

I help maintain node-gyp, I'll see if I can track down if this is an issue with upstream.

[sam-github]

Looks like this is a node-gyp bug, fixed in nodejs/node-gyp#1925, released in v5.0.6. Use a version of npm that includes that version. I just did an npm install -g npm, got npm 6.14.2:

% npm ls -g node-gyp
/home/sam/.nvm/versions/node/v12.16.1/lib
└─┬ npm@6.14.2
  ├── node-gyp@5.1.0 
  └─┬ npm-lifecycle@3.1.4
    └── node-gyp@5.1.0  deduped

Did an npm install of node-rdkafka, and it fixed the error above.

I believe that should close this issue, its not an issue with this project, and its fixed upstream, and released in npm.
