iOS Build Error - Please verify your .env file is correctly formatted.

[akiladevinda]

I git this error after installing pod and run from xcode

Invalid entry in .env file. Please verify your .env file is correctly formatted.

[shllg]

One issue at my setup has been, that ios/ReactNativeConfig/ReadDotEnv.rb doesn't accept anything else except key-value pairs. In my case, I had empty lines and comments in my .env file.

On quick solution is to remove those.

I patched the part of ios/ReactNativeConfig/ReadDotEnv.rb by replacing lines 41-52 with:

raw.split("\n").each_with_index.inject({}) do |h, line_pair|
  line, index = line_pair

  next h if line.nil? || line == '' || line == ' '
  next h unless line.match(comment_line_pattern).nil?

  m = line.match(dotenv_pattern)

  if m.nil?
    abort("Invalid entry in .env file. Please verify your .env file is correctly formatted (line: #{index + 1}, value: #{line}).")
  end

  key = m[:key]
  # Ensure string (in case of empty value) and escape any quotes present in the value.
  val = m[:val].to_s.gsub('"', '\"')
  h.merge(key => val)
end

It ignores comments and empty lines.

So can you show me comment_line_pattern

I also have comments in my .env files, so I updated it with this (same as @shllg's, but without the separate comment_line_pattern var):

raw.split("\n").each_with_index.inject({}) do |h, line_pair|
  line, index = line_pair

  next h if line.nil? || line == '' || line == ' '
  next h if line.match(/^\s*#/)

  m = line.match(dotenv_pattern)

  if m.nil?
    abort("Invalid entry in .env file. Please verify your .env file is correctly formatted (line: #{index + 1}, value: #{line}).")
  end

  key = m[:key]
  # Ensure string (in case of empty value) and escape any quotes present in the value.
  val = m[:val].to_s.gsub('"', '\"')
  h.merge(key => val)
end

I have the same issue. never happened before. remove and pod install again. my .env file does not have invalid entries. no clue what's happening

[wojo1206]

1.4.0 is free of this error. Downgrade to 1.4.0

[sharmapr25]

@josevalb Even .env file is valid still it won't take other .env files apart from .env.dev. I have fixed this issue already raised a pr. #539
Meanwhile, you can edit your package.json like this:
"react-native-config": "git+https://github.com/CoffeeBeansLabs/react-native-config.git"
it will work fine 👍

Looks like it was fixed in v 1.4.2
