env: bash\r: No such file or directory [duplicate] - windows

Question

This question already has answers here:
Are shell scripts sensitive to encoding and line endings?
(14 answers)
Closed last year.
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 what's 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
Note: The $'...' string is an ANSI-C quoted string supported in bash, ksh, and zsh. It is used to ensure that the \r expands to an actual CR character before sed sees the script, because not all sed implementations themselves support \r as an escape sequence.
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 3

It is happening due to windows line endings. To fix the issue follow below steps
For MAC:
brew install dos2unix # Installs dos2unix Mac
find . -type f -exec dos2unix {} \; # recursively removes windows related stuff
For Linux:
sudo apt-get install -y dos2unix # Installs dos2unix Linux
sudo find . -type f -exec dos2unix {} \; # recursively removes windows related stuff
And make sure your git config is set as follows:
git config --global core.autocrlf input
input makes sure to convert CRLF to LF when writing to the object database

Answer 4

Quick command for converting line ending:
dos2unix thescript.sh

Answer 5

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

Answer 6

If you are on MAC, and using VS Code, you can switch from CRLF to LF and save the file again. This will replace all CRLF with LF.

Answer 7

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

Answer 8

In my case I had a wrong git configuration. The git documentation states:
If you’re programming on Windows and working with people who are not
(or vice-versa), you’ll probably run into line-ending issues at some
point
I'm using Mac OS and I exactly have this issue in one of my projects. To solve it I turned autocrlf to true which was wrong.
You can check the autocrlf state of your git configuration like this:
git config core.autocrlf
So if this returns true and the problem occurs within a git repository you'll have to change that configuration to
git config --global core.autocrlf input
on a Mac / Unix system. For Windows only projects you can use
git config --global core.autocrlf false
In my case I deleted the git repository and cloned it again and after that everything worked again as expected.

Answer 9

I used to have this problem when I tried to downgrade flutter
this solved my issue
rm -rf flutter
git config --global core.autocrlf false
git clone git#github.com:flutter/flutter.git
flutter channel stable

Answer 10

This link helped me solving the issue.
https://github.com/tiangolo/uwsgi-nginx-flask-docker/issues/127
I edited my .sh file, replacing all CRLF with LF

Answer 11

In my case:
This error occurs when I downloaded and unzip the WINDOWS version into MAC
and then added the windows version path to .bash_profile or .zprofile
so the solution for me was to remove the paths from (.bash_profile and .zprofile)
then download the mac version by opening the terminal and type:
mkdir src
cd src
git clone https://github.com/flutter/flutter.git -b stable
export PATH="$PATH:pwd/flutter/bin"
flutter doctor
