Unable to compile v0.2.2 #5

Getting a NamespaceCollision error with the latest release:

I have the same issue as yours!

PatrickAlphaC commented 3 years ago

Could you delete the build folder and try again? It looks like your trying to work with 2 different versions of the folder.

omnifient commented 3 years ago

Got the same warning as OP (but no error). Deleting the build folder and re-compiling was successful.

But @PatrickAlphaC can you give more details into what's causing this issue?

PatrickAlphaC commented 3 years ago

@omnifient, basically, you have 2 versions of the same package downloaded in your dependencies, hence the name collision. So deleting the build folder removes the downloaded incorrect dependencies.

I think this would be an improvement to put into brownie.

Closing for now, feel free to follow up.

I am having the same exact problem even after deleting the build folder. It does not really look exactly the same as yours, however, very similar. The error is as following:

I encountered the same problem and followed your instruction. It compiled but I received another error.

can anyone help me with this error? thanks

Please post your config

TheoremaLC commented 2 years ago

Hi, i have the same issue as everyone here, I just took a look at the chainlink/contracts/src/v0.8/interfaces path and found the AggregatorV3Interface, I just dont understand why the compiler keeps returning "source not found: file outside of allowed directries."

JLyncee350 commented 2 years ago

I switched to v0.6 and that worked for me. So try chainlink/contracts/src/v0.6/interfaces. Seems any version past 6 won't compile.

hi, I've porbably found the sollution to this porblem on Win10 VScode :

* 1 create **.vscode** folder and **setting.json** file ... [https://supunkavinda.blog/vscode-editing-settings-json#workspace](url)

* 2 in setting just set up correct path to your smartcontractkit importet by brownie due to compile:

* {
  "solidity.remappings": [
  "@chainlink/=**C:\Users\XPS 15\**.brownie\packages\smartcontractkit\chainlink-brownie-contracts@1.1.1"
