“pip install unroll”: “python setup.py egg_info” failed with error code 1 is a popular Python error which occurs when pip is not upgraded but not only for that reason.
In this article I am going to detail the root of this error and how to solve it, I am also going to present other solutions which worked for other developers.
Describing : “pip install unroll”: “python setup.py egg_info” failed with error code 1 In Python
This error is straight-forward and occurs when you try to install packages with pip.
For example we can try to install the unroll package with pip using the command bellow.
#
pip install unroll
#
This is the error we get
#
Command "python setup.py egg_info" failed with error code 1 in C:\Users\MARKAN~1\AppData\Local\Temp\pip-build-wa7uco0k\unroll\
#
Solution 1 : upgrade pip before you install the package
The first solution is to simply upgrade pip, you can do that with the command bellow
#
python -m pip install --upgrade pip
#
Then try installing the package again, for example you can run this command
#
pip install unroll
#
Solution 2 : install setuptools before installing the package
First, let us start by installing setuptools.
If setuptools is installed, try upgrading it with –upgrade exactly like in the code bellow
#
pip install --upgrade setuptools
#
Now let us try installing the package again
#
pip install unroll
#
If the above does not work, let us check if the module ez_setup is installed, if you can not find it, just go ahead and try installing it with pip
#
pip install ez_setup
#
Now we should be able to install the package running the command
#
pip install unroll
#
This solution should work for you, if it does not work, you can try the possible solutions bellow.

Solution 3 : use sudo for “install python-dev libpq-dev “
The error can also appear when you skip some steps while installing Python and other related packages.
You can run the command bellow to solve the problem
#
sudo apt-get install python-dev libpq-dev
#
Now go to your virtual env and install the package with pip.
Solution 4 : use pip install in the command prompt ( pip install in CMD )
Sometimes, this is a permissions problem, the solution in this case is to :
Run the command prompt as administrator
Then run pip in order to install your chosen package, just like in the line bellow
#
pip install unroll
#
I hope this solution has worked for you as this is the last solution in our article. Good luck.
