Hi,

Can you detail the exact steps you took to install? E.g. did you use the @vendure/create installer or manually add via npm/yarn?

[ahmerdevopsinertia]

@michaelbromley Can you help me in setting up the Braintree sandbox payment in my checkout process.

[michaelbromley]

I suggest you refer to the Braintree developer docs for that. I like to help but I must limit my support to Vendure-specific issues at the moment.

Hi team,

I got the same issue while creating app.

Stacktrace:

vendure npx @vendure/create my-app

Welcome to @vendure/create v1.0.0!

Let's configure a new Vendure project. First a few questions:

✔ Which database are you using? › SQLite
✔ Which programming language will you be using? › TypeScript
✔ Populate with some sample product data? … no / yes
✔ What identifier do you want to use for the superadmin user? … superadmin
✔ What password do you want to use for the superadmin user? … superadmin

Setting up your new Vendure project in /Users/dong.nguyen/Documents/dong-dev/vendure/my-app
This may take a few minutes...

Ensure that there is only one instance of "graphql" in the node_modules
directory. If different versions of "graphql" are the dependencies of other
relied on modules, use "resolutions" to ensure only one version is installed.

Duplicate "graphql" modules cannot be used at the same time since different
versions may have different capabilities and behavior. The data from one
version used in the function from another could produce confusing and
spurious results.

Hi Michael,

I used to latest node & npm version. Thank you for your support.

{
npm: '7.14.0',
node: '14.16.1'
}

[michaelbromley]

I think this might be an issue with changes introduces in npm v7. If you can, try with npm v6.x and let me know if that works.

[dong-nz]

yes, it works for npm v6.x.

[michaelbromley]

OK, thanks for confirming. I need to make some changes then in order for it to work with v7.x

[michaelbromley]

This should now be fixed with the release of v1.0.1 👍
