We are attempting to set up our project on CircleCI and are currently having it fail the build during the yarn install portion.

The error we are receiving is

> $ sed -i ‘’ ‘s/#import \<RCTAnimation/RCTValueAnimatedNode.h\>/#import “RCTValueAnimatedNode.h”/’ ./node\_modules/react-native/Libraries/NativeAnimation/RCTNativeAnimatedNodesManager.h
> 
> sed: can’t read s/#import \<RCTAnimation/RCTValueAnimatedNode.h\>/#import “RCTValueAnimatedNode.h”/: No such file or directory

in our package.json we have a postinstall script that corrects this issue  
`"sed -i '' 's/#import <RCTAnimation\\/RCTValueAnimatedNode.h>/#import \"RCTValueAnimatedNode.h\"/' ./node_modules/react-native/Libraries/NativeAnimation/RCTNativeAnimatedNodesManager.h"`

the issue is we are having difficulties finding a way or where to place this in the config.yml or if that is the right route to go with the correcting the issue.

our config.yml looks like

```
jobs:
  build:
    working_directory: ~/project
    environment:
      LC_ALL: C.UTF-8
      LANG: C.UTF-8
    docker:
      - image: circleci/node:latest

    ## setup
    steps:
      - checkout

      - restore_cache:
          key: yarn-v1-{{ checksum "yarn.lock" }}-{{ arch }}

      - restore_cache:
          key: node-v1-{{ checksum "package.json" }}-{{ arch }}

      - run: yarn install

      - save_cache:
          key: yarn-v1-{{ checksum "yarn.lock" }}-{{ arch }}
          paths:
            - ~/.cache/yarn

      - save_cache:
          key: node-v1-{{ checksum "package.json" }}-{{ arch }}
          paths:
            - node_modules

      ## run tests
      - run:
          name: jest tests
          command: yarn test

```

and advice or incite would be greatly appreciated

Hi @drankin! Thanks for joining the community. I’m looking into this. Is the error stopping the build during a specific package? There were some issues that looked a little like this related to cocoapods, but I don’t know if that’s relevant to you.

@thekatertot Thanks for replying! I was actually able to resolve me issue. By removing the script from my package json.

`"sed -i '' 's/#import <RCTAnimation\\/RCTValueAnimatedNode.h>/#import \"RCTValueAnimatedNode.h\"/' ./node_modules/react-native/Libraries/NativeAnimation/RCTNativeAnimatedNodesManager.h"`

Once we repushed the commit without the script. circleci is now building and running tests for us.

Sorry I didn’t update this thread

No worries at all! I’m happy it was resolved 🙂
