Mac osx python path needed to be set

[songproducer]

When running: npm install

This was the error:

gyp ERR! configure error gyp ERR! stack Error: Can't find Python executable "/usr/local/bin/python", you can set the PYTHON env variable. gyp ERR! stack at failNoPython (/usr/local/lib/node_modules/npm/node_modules/node-gyp/lib/configure.js:449:14) gyp ERR! stack at /usr/local/lib/node_modules/npm/node_modules/node-gyp/lib/configure.js:353:11 gyp ERR! stack at F (/usr/local/lib/node_modules/npm/node_modules/which/which.js:69:16) gyp ERR! stack at E (/usr/local/lib/node_modules/npm/node_modules/which/which.js:81:29) gyp ERR! stack at /usr/local/lib/node_modules/npm/node_modules/which/which.js:90:16 gyp ERR! stack at /usr/local/lib/node_modules/npm/node_modules/which/node_modules/isexe/index.js:44:5 gyp ERR! stack at /usr/local/lib/node_modules/npm/node_modules/which/node_modules/isexe/access.js:8:5 gyp ERR! stack at FSReqWrap.oncomplete (fs.js:123:15) gyp ERR!

Solution is to set the correct python path for npm like this:

npm config set python /usr/bin/python

[roo2]

Hey thanks for reporting! I'm wondering how we can get this to work on both systems with /usr/bin/python and /usr/local/bin/python though, I'm thinking something like

npm config set python $(which python)

but I wonder why that would be necessary, you'd think that node-webcrypto-ossl could use whichever system python is available. But thanks for the report I'll try and investigate this further

[KadeMorton]

@roo2 checking also, is this still an outstanding issue?

[roo2]

Yea still outstanding, I haven't tested this one with OSX yet either

[Yannael]

It also seems that Python >2.5 and <3 must be used for compiling node-webcrypto-ossl

Python 3.6

npm config set python /path/to/python36/python
npm install

gives

> node-webcrypto-ossl@1.0.31 install 
/aletheia-app/node_modules/node-webcrypto-ossl
> node-gyp rebuild

Python 2.7

npm config set python /path/to/python27/python
npm install

works fine. (tested with Anaconda distribution)

@Yannael you legend!

[DarinDev1000]

How do you set python2.7 as the global npm default?

[KadeMorton]

Hi @DarinDev1000 Unfortunately we don't have any developers working on the project at the moment, so I'm not able to answer your query. I am hoping to have some people working on this project in the new year though, so hopefully down the track we will get this sorted for you.

[DarinDev1000]

No problem. I got it figured out.

[latishk]

@DarinDev1000 can u share the solution?

[DarinDev1000]

@DarinDev1000 can u share the solution?

@latishk Here is how to change npm/node defaults. (FYI: After this, python3 is still my bash default. I did not change my PATH) (These instructions were created for a MAC)

This list all npm configurations currently set. npm config list You may see a userconfig file: /Users/<userName>/.npmrc and a globalconfig file: /Users/<userName>/.nvm/versions/node/v8.9.1/etc/npmrc

This list all configs including defaults: npm config ls -l

To set a global config, run: npm config set init-author-name "<Name>" -g This auto sets the npm author name every time you run "npm init". The "-g" tag sets a global config. Otherwise it is a user config. Another way to change this is to add init-author-name = "<Name>"

To set the python path, run: npm config set python </path/to/python2> -g For me, this was: npm config set python "/usr/bin/python2.7" -g or, edit the "globalconfig" file and add: python = "/usr/bin/python2.7"

After changing my npm python path, npm install ran correctly!

I hope this helps. Let me know if you have questions.
