env: bash\r: No such file or directory

Question

I'm trying to install YouCompleteMe from here.

When I execute:

    ./install.sh --clang-completer

I get this error:

    env: bash\r: No such file or directory

I don't know whats wrong with environment variables. Here's my bash path:

which bash 
/bin/bash

Do I need to change it to /usr/bash? If yes, then how should I do that? I tried changing ~/.bashrc file, but it didn't work.

Answer 1

The error message suggests that the script you're invoking has embedded \r characters, which in turn suggests that it has Windows-style \r\n line endings instead of the \n-only line endings bash expects.

As a quick fix, you can remove the \r chars. as follows:

 sed $'s/\r$//' ./install.sh > ./install.Unix.sh

and then run

./install.Unix.sh --clang-completer

However, the larger question is why you've ended up with \r\n-style files - most likely, other files are affected, too.

Perhaps you're running Git on Windows, where a typical configuration is to convert Unix-style \n-only line breaks to Windows-style \r\n line breaks on checking files out and re-converting to \n-only line breaks on committing.

While this makes sense for development on Windows, it gets in the way of installation scenarios like these.

To make Git check out files with Unix-style file endings on Windows - at least temporarily - use:

git config --global core.autocrlf false

Then run your installation commands involving git clone again.

To restore Git's behavior later, run git config --global core.autocrlf true.

Answer 2

Ran into something similar. You can use dos2unix install.sh to convert the line endings. Multiple files via find [pattern] | xargs dos2unix

Answer 3

>vim gradlew
:set fileformat=unix
:wq
>./gradlew clean build

Answer 4

Your file has Windows line endings. Change to Unix line endings.
