I am trying to get a Python script to run on the linux server I'm connected to via ssh. The script uses mysqldb. I have all the other components I need, but when I try to install mySQLdb via setuptools like so:,
python setup.py install
I get the following error report related to the mysql_config command.
sh: mysql_config: command not found
Traceback (most recent call last):
File "setup.py", line 15, in <module>
metadata, options = get_config()
File "/usr/lib/python2.5/MySQL-python-1.2.3/setup_posix.py", line 43, in get_config
libs = mysql_config("libs_r")
File "/usr/lib/python2.5/MySQL-python-1.2.3/setup_posix.py", line 24, in mysql_config
raise EnvironmentError("%s not found" % (mysql_config.path,))
EnvironmentError: mysql_config not found
Has anyone else encountered this error and if so how did you resolve it/what can I do to successfully install mysqldb?
mySQLdb is a python interface for mysql, but it is not mysql itself. And apparently mySQLdb needs the command 'mysql_config', so you need to install that first.
Can you confirm that you did or did not install mysql itself, by running "mysql" from the shell? That should give you a response other than "mysql: command not found".
Which linux distribution are you using? Mysql is pre-packaged for most linux distributions. For example, for debian / ubuntu, installing mysql is as easy as
sudo apt-get install mysql-server
mysql-config is in a different package, which can be installed from (again, assuming debian / ubuntu):
sudo apt-get install libmysqlclient-dev
if you are using mariadb, the drop in replacement for mysql, then run
sudo apt-get install libmariadbclient-dev

https://github.com/JudgeGirl/Judge-sender/issues/4#issuecomment-186542797
I was installing python-mysql on Ubuntu 12.04 using
pip install mysql-python
First I had the same problem:
Not Found "mysql_config"
This worked for me
$ sudo apt-get install libmysqlclient-dev
Then I had this problem:
...
_mysql.c:29:20: error fatal: Python.h: No existe el archivo o el directorio
compilación terminada.
error: command 'gcc' failed with exit status 1
Then I tried with
apt-get install python-dev
(If you're using python3, install python3-dev instead.)
And then I was happy :)
pip install mysql-python

Cleaning up...
(Specific to Mac OS X)
I have tried a lot of things, but these set of commands finally worked for me.
Install mysql
brew install mysql
brew unlink mysql
brew install mysql-connector-c
Add the mysql bin folder to PATH
export PATH=/usr/local/Cellar/mysql/8.0.11/bin:$PATH
mkdir /usr/local/Cellar/lib/
Create a symlink
sudo ln -s /usr/local/Cellar/mysql/8.0.11/lib/libmysqlclient.21.dylib /usr/local/Cellar/lib/libmysqlclient.21.dylib
brew reinstall openssl (source)
Finally, install mysql-client
LIBRARY_PATH=$LIBRARY_PATH:/usr/local/opt/openssl/lib/ pip install mysqlclient
Update:
In case this doesn't work, #vinyll suggests to run brew link mysql before step 8.
On Red Hat I had to do
sudo yum install mysql-devel gcc gcc-devel python-devel
sudo easy_install mysql-python
Then it worked.
On python 3.5.2 + any future version
sudo apt-get install libmysqlclient-dev python-dev
The below worked for me on Ubuntu 12.04 LTS:
apt-get install libmysqlclient-dev python-dev
All though it worked, i still went ahead to do the below:
export PATH=$PATH:/usr/local/mysql/bin/
I got the same error while trying to install mysql-python.
This is how I fixed it.
sudo PATH=/usr/local/mysql/bin/:$PATH pip install mysql-python
The problem was that the installer could not find the mysql_config in the default path. Now it can ..and it worked..
15 warnings generated.

Cleaning up...
Hope this helps.
Thanks.
I fixed this problem with the following steps:
sudo apt-get install libmysqlclient-dev
sudo apt-get install python-dev
sudo python setup.py install
The commands (mysql too) mPATH might be missing.
export PATH=$PATH:/usr/local/mysql/bin/
Step1:-Install Python3 & Python3-dev Both
sudo apt-get install python3 python3-dev
Step2:- Install Python & Mysql Connector
sudo apt-get install libmysqlclient-dev
step3:- Install python mysql client
sudo apt-get install mysqlclient
This will Solve your Problem
The package libmysqlclient-dev is deprecated, so use the below command to fix it.
Package libmysqlclient-dev is not available, but is referred to by another package.
This may mean that the package is missing, has been obsoleted, or
is only available from another source
sudo apt-get install default-libmysqlclient-dev
I think the most convenient way to solve this problem in 2020 is using another python package. We don't need install any other binary software.
Try this
pip install mysql-connector-python
and then
import mysql.connector
mydb = mysql.connector.connect(
host="",
user="",
passwd="",
database=""
)
cursor = mydb.cursor( buffered=True)
cursor.execute('show tables;')
cursor.execute('insert into test values (null, "a",10)')
mydb.commit()
mydb.disconnect()
If you're on macOS and already installed mysql#5.7 via brew install:
brew install mysql-connector-c
brew unlink mysql#5.7
brew link --overwrite --dry-run mysql#5.7 first, to see what symlinks are getting overwritten
brew link --overwrite --force mysql#5.7 to actually overwrite mysql-related symlinks with mysql#5.7
pip install mysqlclient
I fixed it by installing libmysqlclient:
sudo apt-get install libmysqlclient16-dev
In centos 7 this works for me :
yum install mariadb-devel
pip install mysqlclient
The MySQL-python package is using the mysql_config command to learn about the mysql configuration on your host. Your host does not have the mysql_config command.
The MySQL development libraries package (MySQL-devel-xxx) from dev.mysql.com provides this command and the libraries needed by the MySQL-python package. The MySQL-devel packages are found in the download - community server area. The MySQL development library package names start with MySQL-devel and vary based MySQL version and linux platform (e.g. MySQL-devel-5.5.24-1.linux2.6.x86_64.rpm.)
Note that you do not need to install mysql server.
For Alpine Linux:
$ apk add mariadb-dev mariadb-client mariadb-libs
MariaDB is a drop-in replacement for MySQL and became the new standard as of Alpine 3.2. See https://bugs.alpinelinux.org/issues/4264
On my Fedora 23 machine I had to run the following:
sudo dnf install mysql-devel
In CentOS 7 , the following things should be done:
#step1:install mysql
https://dev.mysql.com/doc/mysql-yum-repo-quick-guide/en/
#step2:
sudo yum install mysql-devel
or
sudo yum install mysql-community-devel
I think, following lines can be executed on terminal
sudo ln -s /usr/local/zend/mysql/bin/mysql_config /usr/sbin/
This mysql_config directory is for zend server on MacOSx. You can do it for linux like following lines
sudo ln -s /usr/local/mysql/bin/mysql_config /usr/sbin/
This is default linux mysql directory.
I had this issues and solved if by adding a symlink to mysql_config.
I had installed mysql with homebrew and saw this in the output.
Error: The `brew link` step did not complete successfully
Depending on how you got mysql it will be in different places. In my case /usr/local/Cellar/mysql
Once you know where it is you should be able to ma a symbolic link to where python is looking for it. /usr/local/mysql
This worked for me.
ln -s /usr/local/Cellar/mysql/<< VERSION >>/bin/mysql_config /usr/local/mysql/bin/mysql_config
I had the same problem. I solved it by following this tutorial to install Python with python3-dev on Ubuntu 16.04:
sudo apt-get update
sudo apt-get -y upgrade
sudo apt-get install -y python3-pip
sudo apt-get install build-essential libssl-dev libffi-dev python3-dev
And now you can set up your virtual environment:
sudo apt-get install -y python3-venv
pyvenv my_env
source my_env/bin/activate
also, i fetch the same problem
I fixed this problem with the following steps:
First I run this command
sudo apt-get install libmysqlclient-dev
then I install
pip install mysqlclient==2.1.0
this is worked for me
You need to install the python-dev package:
sudo apt-get install python-dev
sudo apt-get install python-mysqldb
Python 2.5? Sounds like you are using a very old version of Ubuntu Server (Hardy 8.04?) - please confirm which Linux version the server uses.
python-mysql search on ubuntu package database
Some additional info:
From the README of mysql-python -
Red Hat Linux
.............
MySQL-python is pre-packaged in Red Hat Linux 7.x and newer. This
includes Fedora Core and Red Hat Enterprise Linux. You can also
build your own RPM packages as described above.
Debian GNU/Linux
................
Packaged as python-mysqldb_::
# apt-get install python-mysqldb
Or use Synaptic.
.. _python-mysqldb: http://packages.debian.org/python-mysqldb
Ubuntu
......
Same as with Debian.
Footnote: If you really are using a server distribution older than Ubuntu 10.04 then you are out of official support, and should upgrade sooner rather than later.
This method is only for those who know that Mysql is installed but still mysql_config can't be find. This happens if python install can't find mysql_config in your system path, which mostly happens if you have done the installation via .dmg Mac Package or installed at some custom path. The easiest and documented way by MySqlDB is to change the site.cfg. Find the mysql_config which is probably in /usr/local/mysql/bin/ and change the variable namely mysql_config just like below and run the installation again. Don't forget to un-comment it by removing "#"
Change below line
"#mysql_config = /usr/local/bin/mysql_config"
to
"mysql_config = /usr/local/mysql/bin/mysql_config"
depending upon the path in your system.
By the way I used python install after changing the site.cfg
sudo /System/Library/Frameworks/Python.framework/Versions/2.7/bin/python setup.py install
So far, all solutions (Linux) require sudo or root rights to install .
Here is a solution if you do not have root rights and without sudo. (no sudo apt install ...):
Download the .deb file of the libmysqlclient-dev, e.g. from this mirror
Navigate to the downloaded file and run dpkg -x libmysqlclient-dev_<version tag>.deb . This will extract a folder called usr.
Symlink ./usr/bin/mysql_config to somewhere that is found on your $PATH:
ln -s `pwd` /usr/bin/mysql_config FOLDER_IN_YOUR_PATH
It should now be able to find mysql_config
Tested on Ubuntu 18.04.
For macOS Mojave , additional configuration was required, for compilers to find openssl you may need to set:
export LDFLAGS="-L/usr/local/opt/openssl/lib"
export CPPFLAGS="-I/usr/local/opt/openssl/include"
I encountered the same problem, just added the path where *mysql_config* resided to the environment variable PATH and it worked for me.
sudo apt-get build-dep python-mysqldb will install all the dependencies to build the package from PIP/easy_install

I am not able to find the gst.h header file on my Ubuntu environment after the installation of GStreamer packages.
Where do I find the gst.h file so I can build an application with it?
It has been a challenge to find any detailed descriptions on how to install GStreamer libraries to build applications on Linux:
The initial command:
$ sudo apt-get install libgstreamer1.0-dev libgstreamer-plugins-base1.0-dev gstreamer1.0-plugins-good gstreamer1.0-plugins-bad gstreamer1.0-plugins-ugly gstreamer1.0-libav gstreamer1.0-doc gstreamer1.0-tools gstreamer1.0-x gstreamer1.0-alsa gstreamer1.0-pulseaudio
The official documentation here: https://gstreamer.freedesktop.org/documentation/installing/on-linux.html is not describing this *-dev option. Basically you need the libgstreamer1.0-dev to have access to the header file called gst.h (/usr/include/gstreamer-1.0/gst/gst.h)
As of January 22, 2019, I had to downgrade three libraries to be able to install the *-dev GStreamer libraries on Ubuntu 16.04LTS (you may or may not need to downgrade).
You will know if you need to downgrade when you type: $ sudo aptitude install libgstreamer1.0-dev libgstreamer-plugins-base1.0-dev
The libraries to downgrade are pointed out by aptitude:
libglib2.0-dev depends on libglib2.0-0=2.48.0-1ubuntu4, I had 2.48.2-0Ubuntu4.1 installed instead.
libxml2-dev depends on libxml2=2.9.3+dfsg1-1, I had 2.9.3+dfsg1-1ubuntu0.6 installed.
libicu-dev depends on libicu55= 55.1-7 but I had 55.1-7ubuntu0.4 installed.
The three commands below took care of the downgrade:
$ sudo apt-get install libglib2.0-0=2.48.0-1ubuntu4
$ sudo apt-get install libxml2=2.9.3+dfsg1-1
$ sudo apt-get install libicu55=55.1-7
Now if you run: $ sudo find / -name gst.h
You should get now the header file used for development: /usr/include/gstreamer-1.0/gst/gst.h
Also this command here: $ pkg-config --libs gstreamer-1.0
returns: -lgstreamer-1.0 -lgobject-2.0 -lglib-2.0
I'm running Debian on Windows 10 (Windows Subsystem for Linux) and installed Rust using the command:
curl https://sh.rustup.rs -sSf | sh
There were no errors in the install, but when I tried to compile with rustc I got the error linker 'cc' not found.
The Linux Rust installer doesn't check for a compiler toolchain, but seems to assume that you've already got a C linker installed! The best solution is to install the tried-and-true gcc toolchain.
sudo apt install build-essential
If you need to target another architecture, install the appropriate toolchain and target the compilation as follows:
rustc --target=my_target_architecture -C linker=target_toolchain_linker my_rustfile.rs
I ran the following 2 commands and it worked.
sudo apt-get update
sudo apt install build-essential
You have to install some dependencies
for Arch Linux sudo pacman -S base-devel
for Ubuntu sudo apt install build-essential
for Centos sudo yum install gcc
for Solus sudo eopkg it -c system.devel
Solution for CentOS:
yum -y install gcc
if u are on wsl2 - ubuntu try to update the pacakges with following cmds:
sudo apt-get update
sudo apt install build-essential
Solution for Solus:
sudo eopkg it -c system.devel
Please do an "Update and Upgrade" before installing setup tools.
You can fix this problem by adding build essential package in linux
sudo apt install -y build-essential
IF ABOVE IS NOT WORKING: cc is included in the "GCC" package. You need to uninstall GCC and then reinstall it if you have accidentally replaced or removed the cc binary.
I ran the following commands in wsl1, it worked
sudo apt-get update
sudo apt install build-essential
I would like to install cmake the latest version, on Linux environment. I have cmake version 3.5 installed and is not supported by some applications. I tried to upgrade it by uninstalling the current version. But when I reinstall with sudo apt-get install cmake, I get the same version 3.5 re-installed. How do I install the latest version with sudo apt-get install ....?
As far as I know the best way to get the latest CMake version installed on any Linux is not by apt but using pip.
Remove the apt cmake and install the latest version from pip which can easily keep up-to-date.
apt remove cmake -y
pip install cmake --upgrade
Edit: As GNUton has pointed out, the following only works on Ubuntu 16.04 and 18.04(Checked on June 2019).
Now CMake developer team in Kitware Inc provides APT repositiory. It allows you to install latest CMake via apt-get.
If you are using a minimal Ubuntu image or a Docker image, you may need to install the following packages:
sudo apt-get update
sudo apt-get install apt-transport-https ca-certificates gnupg \
software-properties-common wget
Obtain a copy of our signing key:
wget -qO - https://apt.kitware.com/keys/kitware-archive-latest.asc |
sudo apt-key add -
Add the repository to your sources list and update.

You can try the following steps that have worked for me on Ubuntu 18.04.3 LTS as OS of the NVIDIA jetson Nano to get the last version of cmake "cmake-3.14.0" from https://cmake.org/download/.
Delete the installed version in your system
sudo apt purge cmake
Download cmake3.13.4 source
wget https://github.com/Kitware/CMake/releases/download/v3.13.4/cmake-3.13.4.tar.gz
Extract files
tar zxvf cmake-3.13.4.tar.gz
Execute the following commands in this order to build it
cd cmake-3.13.4
sudo ./bootstrap
sudo make
sudo make install
Verify the version is installed correctly
cmake --version
Following the comments made on how to Install the latest CMake version and to post the answer for this question:
Ans:
This depends with Ubuntu OS version currently installed on your PC or Mac. If you have the following Ubuntu OS version then you have this CMake installed or that you could install and reinstall with "sudo apt-get install cmake". Even if you uninstall your version and try to reinstall later version.
Ubuntu 16.04 ships with cmake-3.5.1
Ubuntu 17.10 ships with cmake-3.9.1
Ubuntu 18.04 ships with cmake-3.10.2
Ubuntu 20.04 ships with cmake-3.16.3
Ubuntu 21.04 ships with cmake-3.18.4
Now if you have Ubuntu 16.04 installed and you want cmake-3.10, there is OS problem since you can only install and reinstalled cmake-3.5.1. To get cmake-3.10 or any other version, you have to download and install the package from https://packages.ubuntu.com/. Once you find the latest version of cmake .targz files, you have to build it yourself from the command line.
For CentOS/RHEL you can help these following steps:
yum -y install python-pip
pip install cmake --upgrade
If you are using Google Colab like me and wanted a higher version of cmake in it. Then do the following,
!pip uninstall cmake
!pip install cmake
This will install cmake 3.22 instead of the default version 3.12
pip install cmake --upgrade
if the following occurs after cmake .. :
CMake Error: Could not find CMAKE_ROOT !!!
CMake has most likely not been installed correctly.
Modules directory not found in
/.../.../...
CMake Error: Error executing cmake::LoadCache(). Aborting.
then try
hash -r
the following worked for me:
sudo apt remove cmake
pip install cmake --upgrade
then, I exited the terminal and again entered to check the version with cmake --version command

I was trying to follow this guide: https://github.com/opencomputeproject/onie/blob/master/machine/kvm_x86_64/INSTALL but have gotten stuck.
On this line: make MACHINE=kvm_x86_64 all, I get stg: command not found when it is trying to apply a patch. I get Error 127 on a make command. Here's the output:
I have g++ and git installed. What am I doing wrong?
From the ONIE project wiki Building ONIE:
For a Debian-based system, a Makefile target exists that installs the required packages on your build machine. The ONIE project will maintain this target for the current stable version of Debian. This target requires the use of sudo(8), since package installation requires root privileges:
$ cd build-config
$ sudo apt-get update
$ sudo apt-get install build-essential
$ make debian-prepare-build-host
I built this on Ubuntu Desktop 15.04. For anyone else trying to build ONIE virtual machine, install these packages first:
Packages
qemu-kvm
git
stg
gperf
bison
flex
autoconf
texinfo
gawk
libtool
libtool-bin
libncurses5-dev
libexpat1
libexpat1-dev
python2.7-dev
python3.4-dev
xorriso
You can install most of these with sudo apt-get install <package>. You should be able to follow the ONIE guide now and set it up. Thanks to EtanReisner for all the help!
On Ubuntu, install stg package by,
sudo apt-get install stgit
the error stg: command not found should be resolved.
I want to install Go. I prepared system for support language. But sadly, I can't find Bison and libc6-dev following this command.
sudo apt-get install bison ed gawk gcc libc6-dev make
Then I still can't find the suitable Mercurial for Ubuntu 8.10, which is followed this command.
apt-get install python-setuptools python-dev build-essential
Therefore everyone please guide what I should do in order to install Go completely. My OS is Ubuntu version 8.10. Notice you can post the direct link for me to get packets/files.
Mercurial can typically be installed with
sudo apt-get install mercurial
The package is in universe, which you may not have enabled. The full guide, if you need it, is available here:
https://help.ubuntu.com/community/Mercurial
After installing setuptools et al., the go installation instructions say that you should install mercurial with easy-install, i.e. sudo easy_install mercurial. Are you having trouble with easy_install?
In order to install go with Homebrew run the following command on the terminal:
$ brew install golang
To check the version of go run the following command:
$ go version
To see the location run:
$ which go
To uninstall go :
$ sudo apt-get remove golang-go
