“ pip install unroll”：“ python setup.py egg_info”失败，错误代码为1

I’m new to Python and have been trying to install some packages with pip.

But pip install unroll gives me

Command “python setup.py egg_info” failed with error code 1 in C:\Users\MARKAN~1\AppData\Local\Temp\pip-build-wa7uco0k\unroll\

How can I solve this?

About the error code

According to the Python documentation:

This module makes available standard errno system symbols. The value of each symbol is the corresponding integer value. The names and descriptions are borrowed from linux/include/errno.h, which should be pretty all-inclusive.

Error code 1 is defined in errno.h and means Operation not permitted.

About your error

Your setuptools do not appear to be installed. Just follow the Installation Instructions from the PyPI website.

If it’s already installed, try

pip install --upgrade setuptools

If it’s already up to date, check that the module ez_setup is not missing. If it is, then

pip install ez_setup

Then try again

pip install unroll

If it’s still not working, maybe pip didn’t install/upgrade setup_tools properly so you might want to try

easy_install -U setuptools

And again

pip install unroll

Here’s a little guide explaining a little bit how I usually install new packages on Python + Windows. It seems you’re using Windows paths, so this answer will stick to that particular SO:

• I never use a system-wide Python installation. I only use virtualenvs, and usually I try to have the latest version of 2.x & 3.x.
• My first attempt is always doing pip install package_i_want in some of my Visual Studio command prompts. What Visual Studio command prompt? Well, ideally the Visual Studio which matches the one which was used to build Python. For instance, let’s say your Python installation says Python 2.7.11 (v2.7.11:6d1b6a68f775, Dec 5 2015, 20:40:30) [MSC v.1500 64 bit (AMD64)] on win32. The version of Visual Studio used to compile Python can be found here, so v1500 means I’d be using vs2008 x64 command prompt
• If the previous step failed for some reason I just try using easy_install package_i_want
• If the previous step failed for some reason I go to gohlke website and I check whether my package is available over there. If it’s so, I’m lucky, I just download it into my virtualenv and then I just go to that location using a command prompt and I do pip install package_i_want.whl
• If the previous step didn’t succeed I’ll just try to build the wheel myself and once it’s generated I’ll try to install it with pip install package_i_want.whl

Now, if we focus in your specific problem, where you’re having a hard time installing the unroll package. It seems the fastest way to install it is doing something like this:

• git clone https://github.com/Zulko/unroll
• cd unroll && python setup.py bdist_wheel
• Copy the generated unroll-0.1.0-py2-none-any.whl file from the created dist folder into your virtualenv.
• pip install unroll-0.1.0-py2-none-any.whl

That way it will install without any problems. To check it really works, just login into the Python installation and try import unroll, it shouldn’t complain.

One last note: This method works almost 99% of the time, and sometimes you’ll find some pip packages which are specific to Unix or Mac OS X, in that case, when that happens I’m afraid the best way to get a Windows version is either posting some issues to the main developers or having some fun by yourself porting to Windows (typically a few hours if you’re not lucky) :)

It was resolved after upgrading pip:

python -m pip install --upgrade pip
pip install "package-name"

I got stuck exactly with the same error with psycopg2. It looks like I skipped a few steps while installing Python and related packages.

1. sudo apt-get install python-dev libpq-dev
2. Go to your virtual env
3. pip install psycopg2

(In your case you need to replace psycopg2 with the package you have an issue with.)

It worked seamlessly.

I got this same error while installing mitmproxy using pip3. The below command fixed this:

pip3 install --upgrade setuptools

• Download and install the Microsoft Visual C++ Compiler for Python 2.7 from https://www.microsoft.com/en-in/download/details.aspx?id=44266 – this package contains the compiler and set of system headers necessary for producing binary wheels for Python 2.7 packages.
• Open a command prompt in elevated mode (run as administrator)
• Firstly do pip install ez_setup
• Then do pip install unroll (It will start installing numpy, music21, decorator, imageio, tqdm, moviepy, unroll) # Please be patient for music21 installation

Python 2.7.11 64 bit used

Other way:

sudo apt-get install python-psycopg2 python-mysqldb

I had the same problem.

The problem was:

pyparsing 2.2 was already installed and my requirements.txt was trying to install pyparsing 2.0.1 which throw this error

Context: I was using virtualenv, and it seems the 2.2 came from my global OS Python site-packages, but even with --no-site-packages flag (now by default in last virtualenv) the 2.2 was still present. Surely because I installed Python from their website and it added Python libraries to my $PATH.

Maybe a pip install --ignore-installed would have worked.

Solution: as I needed to move forwards, I just removed the pyparsing==2.0.1 from my requirements.txt.

I ran into the same error code when trying to install a Python module with pip. @Hackndo noted that the documentation indicate a security issue.

Based on that answer, my problem was solved by running the pip install command with sudo prefixed:

sudo pip install python-mpd2

I had the same issue when installing the “Twisted” library and solved it by running the following command on Ubuntu 16.04 (Xenial Xerus):

sudo apt-get install python-setuptools python-dev build-essential

I tried all of the above with no success. I then updated my Python version from 2.7.10 to 2.7.13, and it resolved the problems that I was experiencing.

That means some packages in pip are old or not correctly installed.

1. Try checking version and then upgrading pip.Use auto remove if that works.

2. If the pip command shows an error all the time for any command or it freezes, etc.

3. The best solution is to uninstall it or remove it completely.

4. Install a fresh pip and then update and upgrade your system.

5. I have given a solution to installing pip fresh here – python: can’t open file get-pip.py error 2] no such file or directory

This was the easier way for me:

pip2 install Name

So if you was using pip, try to use pip3 or pip2

It should solve the problem.

pip3 install –upgrade setuptools WARNING: pip is being invoked by an old script wrapper. This will fail in a future version of pip. Please see https://github.com/pypa/pip/issues/5599 for advice on fixing the underlying issue.

******To avoid this problem you can invoke Python with ‘-m pip’ instead of running pip directly.******

use python3 -m pip “command” eg: python3 -m pip install –user pyqt5

This worked for me:

sudo xcodebuild -license

Upgrading Python to version 3 fixed my problem. Nothing else did.

I downloaded the .whl file from http://www.lfd.uci.edu/~gohlke/pythonlibs/ and then did:

pip install scipy-0.19.1-cp27-cp27m-win32.whl

Note that the version you need to use (win32/win_amd-64) depends on the version of Python and not that of Windows.

I had this problem using virtualenvs (with pipenv) on my new development setup.

I could only solve it by upgrading the psycopg2 version from 2.6.2 to 2.7.3. More information is at https://github.com/psycopg/psycopg2/issues/594

I faced the same problem with the same error message but on Ubuntu 16.04 LTS (Xenial Xerus) instead:

Command “python setup.py egg_info” failed with error code 1 in /tmp/pip-install-w71uo1rg/poster/

I tested all the solutions provided above and none of them worked for me. I read the full TraceBack and found out I had to create the virtual environment with Python version 2.7 instead (the default one uses Python 3.5 instead):

virtualenv --python=/usr/bin/python2.7 my_venv

Once I activated it, I run pip install unirest successfully.

try on linux:

sudo apt install python-pip python-bluez libbluetooth-dev libboost-python-dev libboost-thread-dev libglib2.0-dev bluez bluez-hcidump

I solved it on Centos 7 by using:

sudo yum install libcurl-devel

Had the same problem on my Win10 PC with different packages and tried everything mentioned so far.

Finally solved it by disabling Comodo Auto-Containment.

Since nobody has mentioned it yet, I hope it helps someone.

I had the same problem and was able to fix by doing the following.

Windows Python needs Visual C++ libraries installed via the SDK to build code, such as via setuptools.extension.Extension or numpy.distutils.core.Extension. For example, building f2py modules in Windows with Python requires Visual C++ SDK as installed above. On Linux and Mac, the C++ libraries are installed with the compiler.

https://www.scivision.co/python-windows-visual-c++-14-required/

Following below command worked for me

[root@sandbox ~]# pip install google-api-python-client==1.6.4

Methods to solve setup.pu egg_info issue when updating setuptools or not other methods doesnot works.

1. If CONDA version of the library is available to install use conda instead of pip.
2. Clone the library repo and then try installation by pip install -e . or by python setup.py install
