Hello everyone,

I’m trying to set up locally the [daml-dit-integration-exberry](https://github.com/digital-asset/daml-dit-integration-exberry) project but i’m facing some issues.  
First i had to change the makefile and replace the use of non existent file “dabl-meta.yaml” by the existent one “dit-meta.yaml” so the “make all” command can work correctly.

```haskell
${DIT_NAME}: dabl-meta.yaml Makefile ${PKG_FILES} ${SRC_FILES} requirements.txt
	ddit build --force --integration

```

Now and following this [readme](https://github.com/digital-asset/da-marketplace/blob/921cbe9058d596e851461bd199a412a0e857a326/docs/local_development.md), I’m trying to execute the command

```haskell
DABL_INTEGRATION_TYPE_ID=com.projectdabl.integrations.exberry.integration ./dabl-integration-exberry-{VERSION}.dit

```

But it is failing with the following stacktrace:

```haskell
DABL_INTEGRATION_TYPE_ID=com.projectdabl.integrations.exberry.integration ./dabl-integration-exberry-0.8.1.dit
Traceback (most recent call last):

Hey joaogaspar,

We’ve had a few updates to how integrations are built and run that don’t seem to have made it into the documentation or `Makefile`.

To run the integration, please give this command a try:

```haskell
ddit run --party=Exchange com.projectdabl.integrations.exberry.integration

```

I would also rename `dabl-meta.yaml` back to `dit-meta.yaml` and change `dabl-meta.yaml` to `dit-meta.yaml` in the `Makefile`.

Please let me know if you have any other issues. I will update our repos to reflect these changes, thanks for pointing this out!

Hey Alex,

Thanks for the quick response.  
After executing the command you mentioned i got this:

```haskell
  Building wheel for cryptography (PEP 517) ... error
  ERROR: Command errored out with exit status 1:

 error: can't find Rust compiler

  If you are using an outdated pip version, it is possible a prebuilt wheel is available for this package but pip is not able to install from it. Installing from the wheel would avoid the need for a Rust compiler.

  To update pip, run:

      pip install --upgrade pip

  and then retry package installation.

  If you did intend to build this package from source, try installing a Rust compiler from your system package manager and ensure it is on the PATH during installation. Alternatively, rustup (available at https://rustup.rs) is the recommended way to download and update the Rust compiler toolchain.

  This package requires Rust >=1.41.0.
  ----------------------------------------
  ERROR: Failed building wheel for cryptography

```

My pip is updated so should I get rust? I’m asking because it’s not in the requirements.  
Thanks

That’s odd. Which version of OSX are you running? There should be a prebuilt wheel for the `cryptography` package that pip should fetch - for me, pip downloads `cryptography-35.0.0-cp36-abi3-macosx_10_10_x86_64.whl`. Are the other packages being downloaded or are they all built when you get that error?

I’m already on Monterey 12.0.1.  
Attached there’s a file with the full log of the execution so you can check it .

Thanks for sending the logs. Can you try running

```haskell
./.ddit-venv/bin/pip install --upgrade pip

```

from the integration’s directory, and then trying to run the integration again?

If that doesn’t fix it, please also try

```haskell
./.ddit-venv/bin/pip3 install --upgrade pip

Thanks for your effort Alex, but unfortunately it didn’t work.  
I’ve tried before running the integration and of course it didn’t work because the directory .ddit-venv still doesn’t exist. So i tried after running the integration and the previous error is thrown and i got this:

```haskell
joaogaspar@MacBook-Pro-de-Joao-IntellectEU2 daml-dit-integration-exberry % make start
ddit run --party=Exchange com.projectdabl.integrations.exberry.integration

```

Thanks.

I am going to look more into this, but in the meantime, I’ve uploaded my `.ddit-venv` if you want to extract it into your integration folder directly and give it a try: [https://github.com/digital-asset/daml-dit-integration-exberry/files/7522020/ddit-venv.zip](https://github.com/digital-asset/daml-dit-integration-exberry/files/7522020/ddit-venv.zip).
