Bug or issue?

Please try to answer the following questions:

• What version of Neutrino are you using? N/A, issue with current create-project
• Are you trying to use any presets? If so, which ones, and what versions?
• Are you using the Yarn client or the npm client? What version? Using npm 6.4.1 (yarn 0.18.1 is installed, but shouldn't be used)
• What version of Node.js are you using? node 8.16.0
• What operating system are you using? Ubuntu for Windows 10
• What did you do? Ran npx @neutrinojs/create-project test-component to start a new project
• What did you expect to happen? Project to be created with all dependencies installed
• What actually happened, contrary to your expectations? Project was created, but no devDependencies were installed or added to package.json

Hooray, I successfully created your project!

I have added a few yarn scripts to help you get started:
  • To build your project run:  yarn build
  • To start your project locally run:  yarn start
  • To execute tests run:  yarn test
  • To lint your project manually run:  yarn lint
    You can also fix some linting problems with:  yarn lint --fix

Now change your directory to the following to get started:
  cd test-component

Upgrading yarn fixed the issue; however, why is create-project using yarn if I called it using npx?

[edmorley]

Hi! Thank you for opening an issue. Neutrino 8 requires yarn 1.2.1 or newer, hence the error seen above. However I agree that is a bug that it's being used if create-project is run via npx. As such, this is a duplicate of #1260, which has just been fixed by #1396 (on master only at the moment). The workaround in the meantime would be to remove yarn from PATH temporarily before running create-project, or else to upgrade or uninstall yarn.

I would also recommend not using Neutrino 8, and instead trying the v9 release candidates, since they fix many bugs. (The Neutrino version still applies to create-project). See #1129 for details.
