the same for me

[jf-bloom]

I was having a similar build issue on OS X and on linux.

node v10.3.0
npm 6.1.0
libxmljs 0.9.1

I was able to get this to install correctly using npm install --build-from-source. This workaround is successful on both OS X and linux. I can also build the project with no errors if I clone libxmljs repo locally.

Here was the error on linux (npm install without --build-from-source):

I should also add, in case it can help solve the issue, that when I repeatedly ran npm install on OS X I would get different files in the No such file or directory error message.

[richtera]

Is there any news on this, it still failed for me and the commented "workarounds" don't seem to work. Things work fine with v9 of node, but I need to use v10 for some other things.

[rezonant]

Hrm, the workaround of using npm install --build-from-source worked for me on Ubuntu (digital ocean). What platform are you building on? Did the error message change with --build-from-source?

[richtera]

I am running plain Mac OS with nvm running v10.7.0.
I added a gist with the failed and successful package.json and build output. Very strange.
https://gist.github.com/richtera/3855873f20df2c77a5fcb589453469d7
What's interesting is that the yarn add libxmljs only fails in the context of my package.json. If I create a new empty directory and just do yarn add libxmljs it works fine.
Same node, npm and yarn

$ node -v
v10.7.0
$ npm -v
6.3.0
$ yarn -v
1.9.4

[richtera]

Again both cases (and I tried another package.json with the same problem) work with v9 of node.

[jj0b]

I was able to fix the same error for myself on MacOS by switching to an environment where Python 2.7 was the default Python.

node-gyp is not compatible with Python 3.x and libxmljs uses node-gyp.

[jmmalunao]

I was able to fix the same error for myself on MacOS by switching to an environment where Python 2.7 was the default Python.

node-gyp is not compatible with Python 3.x and libxmljs uses node-gyp.

Installed Python2.7 some errors removed but still got build error with recommendation to install .NET Framework 2.0 SDK, installed and now all is working.

[DanielRuf]

It seems some of you do not have the required build tools (python2) and use some old one (node-waf was before node-gyp).

[DanielRuf]

I think we can close the initial issue as it was about libxmljs 0.0.7.
