Resulting path names are too long

[aburgm]

I failed to install nodejs on Windows 7 with conda because the resulting path names are too long. While this is ultimately a problem that could be fixed in conda or Python (and seems to be in Python 3.6 on Windows 10), I wonder if there is anything we could do in the nodejs recipe to obtain a flatter directory structure?

This should be fixed (or at least slightly less likely to occur) with the lates nodejs 8 package.

Latest version should be 8.8.1 but I guess those did not build, see

https://ci.appveyor.com/project/conda-forge/nodejs-feedstock

The odd thing is that they seems to pass on the PR. Here is the error on master:

Nope, that is the PR, sorry.

Same issue here with 9.9.0 on conda-forge

however the 8.9.3-hd6b2f15_0 version on the default anaconda channel seemed to install correctly.

Could those of you running into this problem please supply more information in issue ( conda/conda#7203 )? As it is, there is not enough information to solve the issue.

[guillaumedavidphd]

See #29 for more info

[jakirkham]

This is ultimately a conda problem that has been filed as issue ( conda/conda#7203 ). Please follow along and share info there. FWIW there is a suggested workaround for this issue. Going to close to consolidate the discussion in that issue. Thanks all for reporting and sharing details.
