Installation of pythonnet on Ubuntu 18.04 - problems with nuget.exe - linux

I try to install the pythonnet library on linux, but I can have trouble with nuget/mono.
I tryed to run the following (Install pythonnet on Ubuntu 18.04, Python 3.6.7 64-bit, Mono 5.16 fails):
sudo apt update
sudo apt-get install clang
sudo apt install nuget
git config --global http.proxy http://my.proxy.address:port
/usr/bin/python3 -m pip install -U pycparser --user
/usr/bin/python3 -m pip install -U pythonnet --user
However, this results in the following error:
mono tools/nuget/nuget.exe update -self' returned non-zero exit status 1.
When I clone the repository from github and just run mono tools/nuget/nuget.exe update -self, I get the following error:
Checking for updates from https://www.nuget.org/api/v2/. Invalid URI: Invalid port specified.
I came across this link: https://github.com/NuGet/Home/issues/2880, but most of the advice is Windows focussed. Does anyone know how to fix this?
Thank you!

I had the same problem and needed to install mono first:
sudo apt-get install mono-complete

How to properly install azure-cli in Ubuntu 20.04 using homebrew?

I am trying to install the azure-cli locally from a cloned repository. I successfully installed homebrew on my end. However, when I try to install the azure-cli, the error occurs below at the very end:
From the repository, the instructions work on other devices, both on windows and linux. I don't know why it won't work on my end:
Step 1: /bin/bash -c "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/HEAD/install.sh)"
Step 2: brew tap-new <name>/azure-cli
Step 3: brew extract azure-cli <name>/azure-cli --version 2.29.2
Step 4: brew install <name>/azure-cli/azure-cli#2.29.2 (This is where error occurs)
*Note: the section is the name of the user of my laptop.
Other part of the installation process I've successfully installed:
Decorator setup:
sudo apt install python3-pip
sudo /usr/bin/pip3 install --system decorator
Azure Functions Core Tools:
npm i -g azure-functions-core-tools#3 --unsafe-perm true
We have ran the below cmdlets in our local environment to install Home brew & azure cli on azure Linux virtual machine which is running with Ubuntu 20.04 image.
Here are the list of Linux cmdlets used:
sudo apt update
sudo apt-get install build-essential
sudo apt install git -y ##installing git
/bin/bash -c "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/HEAD/install.sh)" ##Run Homebrew installation Script
eval "$(/home/linuxbrew/.linuxbrew/bin/brew shellenv)" ##Add Homebrew to your path
To ensure everything is working correctly to use brew, we can run its command
brew doctor
It may give the warning to install GCC and to remove that simply install it using brew
brew install gcc
To install azure-cli with last version as per the documentation
brew install azure-cli
Here is the output screenshot for reference:
You can refer this blog to install home brew on Ubuntu20.04 linux machine.

I'm getting a "command not found" error when trying to install "xgboost" in an Ubuntu 16.04 Virtual Machine

I'm trying to install xgboost in an Ubuntu 16.04 virtual machine.
I'm following this guide and ran this command:
cmake ..
I got this error:
-bash: cmake: command not found
What am I doing wrong and how can I get rid of this error?
Try this:
sudo apt-get install software-properties-common
sudo add-apt-repository ppa:george-edison55/cmake-3.x
sudo apt-get update
sudo apt-get install cmake
UPDATE:
Or you can just use pip:
sudo pip3 install xgboost
It appears you're getting this error because you don't have the cmake command installed, you can fix this by running:
sudo apt install cmake
I don't know if you've missed this but you can also install xgboost using pip (or in your case pip3), like this:
pip3 install xgboost
NOTE: depending on how your user/project is set up you might need to use the sudo command to grant pip3 write privileges to certain (root) directories, if this is the case, you'd use:
sudo pip3 install xgboost
NOTE: if you don't have pip3 installed, you can install it using:
sudo apt install python3 python3-pip
Good luck.

flask-mysqldb support for Python 3.6? [duplicate]

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
Reference:
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

Successfully installed 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.

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

How to install python3.4 in home 'not root'? ensurepip failure

I do not have root privileges on the Red Hat Linux machine I am installing python3.4 on.
Downloaded Python-3.4.1.tgz
tar -xzf Python-3.4.1.tgz
./configure
makealtinstall --with-ensurepip=install prefix=~ exec-prefix=~
Python3 does install, but I don't have pip.
I get the following error:
Ignoring ensurepip failure: pip 1.5.6 requires SSL/TLS
I don't have root access so I cannot install via:
sudo apt-get install libssl-dev openssl
I do have a working version of openssl.
Does anyone have suggestions I could try?
Since you are in RedHat, you have to install openssl-devel
yum install openssl-devel
Or you can install it later with get-pip.py
The complete procedure for installing Python 3.4 with pip3/pip3.4 on RHEL7 is below. For Ubuntu 12.04 LTS replace yum with apt-get, openssl-devel with libssl-dev and you are good to go:
sudo yum install -y gcc make openssl-devel openssl
wget https://www.python.org/ftp/python/3.4.3/Python-3.4.3.tgz
tar -xf Python-3.4.3.tgz
cd Python-3.4.3/
./configure --with-ensurepip=install
make
make install
Alternatively, you can run make altinstall depending on whether you need create python link or not.
