Why can't Python.h be found?

Your install is failing because you don't have the python development headers installed. You can do this through apt on ubuntu/debian with:

sudo apt-get install python-dev 

for python3 use:

sudo apt-get install python3-dev

For eventlet you might also need the libevent libraries installed so if you get an error talking about that you can install libevent with:

sudo apt-get install libevent-dev

If you're not familiar with a command line, some of these errors can seem cryptic or confusing. Below is a full list of errors that can occur while in MS-DOS and the Windows command line.

For Fedora:

and finally:

sudo easy_install gevent

The error command has  Re: ERROR!!! Command is disabled. I just ran across a similar situation. You'll need to hold down the "Mode" button during startup for a few seconds. That'll get you out of the controller mode, and should allow you to set the controller IP and so forth. That said, if the AP is on the same subnet as the controller,

I tried all the above answers. But what worked for me was for CentOS:

sudo yum -y install gcc
sudo yum install python-devel

error command, For some CMS commands, you may receive messages for syntax errors, such as those listed below, if you have specified a command format incorrectly.

For Redhat Versions(Centos 7) Use below command to install Python Development Package

Python 2.7

sudo yum install python-dev

Python 3.4

Still if your problem not solved then try installing below packages -

sudo yum install python-devel

sudo yum install openssl-devel

sudo yum install libffi-devel

Command Syntax Error Messages, This MATLAB function throws an error and displays an error message. exception and returns control to the Command Prompt, you can use MException.​last . That is what I was thinking too but I have 2 remarks. 1) I opened the solution file of the private repo and the soultion's package.json matches mine (plus, yesterday eberything was working) 2) How can I run the JS files in the folder lib if i do not run yarn start?

On MacOS I had trouble installing fbprophet which requires pystan which requires gcc to compile. I would consistently get the same error: command 'gcc' failed with exit status 1

I think I fixed the problem for myself thus:

I used brew install gcc to install the newest version, which ended up being gcc-8

Then I made sure that when gcc ran it would use gcc-8 instead.

It either worked because I added alias gcc='gcc-8 in my .zshrc (same as .bashrc but for zsh), or because I ran export PATH=/usr/local/bin:$PATH (see comment)

Also: all my attempts were inside a virtual environment and I only succeeded by installing fbprophet globally (with pip), but still no success inside a venv

Intro to Tcl: Creating Control Structures and Exception Handling, The first parameter of the error handler is the Context while the second one is an exception that is derived from CommandError . A list of errors is found in the  Errorlevel and Exit codes. Almost all applications and utilities will set an Exit Code when they complete/terminate. The exit codes that are set do vary, in general a code of 0 (false) will indicate successful completion.

  • FWIW, you definitely need both python-dev and libevent-dev. Thanks!
  • For fedora, you can use: sudo yum install python-devel
  • I suggest running sudo apt-get update before running these 2 commands. I was getting error with sudo apt-get install python-dev.
  • I have the same error but have python-devel installed and system is updated with yum -y install updates.. what else could the issue be?
  • If using Python 2.6: sudo apt-get install python2.6-dev
  • worked with - sudo yum -y install gcc
  • sudo yum install python-devel sudo yum install libevent-devel worked for me
  • solved my problem too. unable to execute 'gcc': No such file or directory error: command 'gcc' failed with exit status 1
  • use sudo yum install python34-devel for python 3.x as the other is only for python 2.x
  • No package python-dev available. I am getting this.
  • Hi @NishantKumar make sure you are working on centos and installing it for python2.x. You can also try "sudo yum install python-devel"
  • @NishantKumar you get that message because on centOS the python-dev package is under the name python-devel, so use yum install python-devel
  • When I run, it gives me the error "unable to execute 'gcc': No such file or directory"
  • @Sarang that means you haven't install gcc yet, execute:"yum -y install gcc"
