React-native-config: Xcode 10.2: Unable to spawn process (Exec format error)

[bnolens]

Hi all,

I updated from Xcode 10.1 to Xcode 10.2 and got this error when building now
error: unable to spawn process (Exec format error)

I've got a little build script executed during build that basically runs BuildDotenvConfig.ruby inside react-native-config/ios/ReactNativeConfig, to build the dotenv files.
The error happens when this script is executing.

This is the script that runs during build:

#/bin/sh

RNCDIR="./node_modules/react-native-config/ios"

if [ ! -z "$SYMROOT" ]; then
  # Ensure directories exist before copying files
  mkdir -p $SYMROOT
  mkdir -p $BUILD_DIR

  # Build dotenv
  cd $RNCDIR
  ./ReactNativeConfig/BuildDotenvConfig.ruby
  cd -

  # Copy generated dotenv files to node_modules directory
  cp "$BUILD_DIR/GeneratedInfoPlistDotEnv.h" "$RNCDIR/ReactNativeConfig/GeneratedInfoPlistDotEnv.h"
  cp "$SYMROOT/GeneratedDotEnv.m" "$RNCDIR/ReactNativeConfig/GeneratedDotEnv.m"
fi

Does somebody know what this might be?
I currently downgraded my Xcode version to 10.1 to fix this.

Hello everyone, I also have the same problem as @bnolens after upgrade Xcode to 10.2.
The solution from @bnolens worked for me too.

But I doubt it would be how Xcode 10.2 interpret shell script to run on Mac OS.
So if anyone who know how to change shell script follow to the right format, I am thank you in advance.
(I'm sorry if I am misunderstanding this bug)

My Environment are

1. react-native: 0.58.6
2. react-native-config: 0.11.7

and I using cocoa-pod to build IOS applications.

Guys, just change the first line of scripts/build-env.sh from #/bin/sh to #!/bin/sh

[bnolens]

Changing the first line to #!/bin/sh fixed it for me. Thanks @stephenkopylov! 🍺

@stephenkopylov I love you man. I'm just curious. How do you know this stuff? What was the clue?

[raphaelbadia]

Where do you add the scripts/build-env.sh file ? The readme doesn't talk about it
