Not able to install librosa

I am not able to install librosa in Ubuntu 18.04. I have tried the following commands, all are failed.
pip install librosa
python3.8 -m pip install librosa
sudo pip install librosa
pip install -u librosa
The below error I am getting:

I came across the same issues too.
There are several steps that helped me, but I cannot define the exact one. So I will list all:
First, update setuptools and wheel
python3 -m pip install --upgrade pip setuptools wheel
Second
python setup.py bdist_wheel
Try to install the previous version of librosa
pip install librosa==0.7.2
I hope the first two steps will help

Pip gives error when installing vpnotebook

Vpython versions are not available from their website, but according to https://groups.google.com/forum/#!topic/vpython-users/AmIZF2v4Wkc, "pip install vpython" should work for any version of Python.
I entered "pip install vpython" into the windows command prompt. After several minutes of downloading, pip gave me the following error:

The immediate fix is to install jupyter before you install vpnotebook:
pip install jupyter
Thanks for reporting this; in the future issues posted at either the location #user1114907 indicated or at the main github repo: https://github.com/BruceSherwood/vpython-jupyter/issues

This appears to be a bug in vpnotebook, upon which vpython depends. Trying to install vpnotebook in both Python 2.7 and 3.5 fails with the same error, which appears to have been caused by the package's authors not even using a basic linter. I would suggest reporting this to said authors, but there are no contact details, repositories, or project websites listed on the package's PyPI page.

If your python version is greater than 2.7.9, skip to step 3
Install python version > 2.7.9 [2.7.14 is the latest]
Download latest version of python
extract the archive
./configure
make
make install
Download and re-install pip
curl https://bootstrap.pypa.io/get-pip.py -o get-pip.py
sudo python get-pip.py
Install jupyter First
sudo pip install jupyter
Then, install vpython
sudo pip install vpython

How do I install language_check in this case?

I check the sources of the file download_lt.py (github language_check).
It appears that the error occurs when you try to move the folder language_check/LanguageTool-X.Y with the command os.rename() from your TemporaryFile to your Anaconda Lib folder.
So far, #Orions is right, it is a permission problem.
Firstly, you should check your folder permission:
Go to your Local folder (should be C:\Users\Gaurav M\AppData\Local)
Right-click on Temp folder on select properties
Go to Security tab and Edit and Add your name if it doesn't appear under Group or user names.
Repeat the operation for your Anaconda folder. (should be C:\Users\Gaurav M\Anaconda)
Secondly, you can try:
pip install --user language_check
But the pip --user option install the package only for the user.
Install to the Python user install directory for your platform. Typically ~/.local/, or %APPDATA%Python on Windows. (See the Python documentation for site.USER_BASE for full details.)
Last but not least,
I presume you are using cmd or powershellas Command-line interpreter.
In my opinion, using cygwin on Windows makes a lot of things easier. Although It could be painful to configure, I would recommend a pre-configure cygwin solution like Babun.
Good luck!

Compiling Cx-Freeze under Ubuntu

For the entire day I have been attempting to compile cx-Freeze under Ubuntu 14.04 and had no luck. So I gave up and decided to ask experts here.
What I have
Ubuntu 14.04
Python 3.4
python-dev, python3-dev, python3.4-dev installed (I know this common issue)
Sources of cx-Freeze 4.3.3
I tried two ways:
install from the sources
install by pip
Install from the sources
sudo python3 setup.py install
What I got
a lot of
MyPath/cx_Freeze-4.3.3/source/bases/Console.c:24: undefined reference to `PyErr_Print'
MyPath/cx_Freeze-4.3.3/source/bases/Console.c:24: undefined reference to `Py_FatalError'
and then
collect2: error: ld returned 1 exit status
error: command 'i686-linux-gnu-gcc' failed with exit status 1
Install by pip
sudo pip3 install cx-Freeze
What I got
collect2: error: ld returned 1 exit status
error: command 'i686-linux-gnu-gcc' failed with exit status 1

Thanks to Thomas K

From cx_freeze/issues
Download
You need to download the source code
For python 3.3 and 3.4:
sudo apt-get install python3-dev
sudo apt-get install libssl-dev
Open setup.py and change the line
if not vars.get("Py_ENABLE_SHARED", 0):
to
if True:
python3 setup.py build
sudo python3 setup.py install
For python 2.7:
sudo apt-get install python-dev
sudo apt-get install libssl-dev
Open setup.py and change the line
if not vars.get("Py_ENABLE_SHARED", 0):
to
if True:
python setup.py build
sudo python setup.py install

GriMel's answer worked for me. Until cx_freeze releases an update for this, I'm including a set of steps that you can do to get this working using GriMels' solution.
# create and activate virtualenv (as desired)
virtualenv envs/test_cxfreeze
. ./envs/test_cxfreeze/bin/activate
# download cxfreeze; do not install yet
mkdir src/
pip install --download=./src/ cx-freeze
tar zxvf ./src/cx_Freeze-4.3.4.tar.gz -C ./src/
# fix bug in setup.py
vim src/cx_Freeze-4.3.4/setup.py

< if True:

> if not vars.get("Py_ENABLE_SHARED", 0):

pip install ./src/cx_Freeze-4.3.4/
I've also opened up a bitbucket issue with what appears to be the source repo.
https://bitbucket.org/anthony_tuininga/cx_freeze/issues/153/cx_freeze-434-compile-error-on-ubuntu-1404

Looks like you might have a typo
change
sudo pip3 install cx-Freeze
to
sudo pip3 install cx_Freeze

Installation of Pandas fails on Ubuntu 12.04

As per the Pandas community page (http://pandas.pydata.org/community.html), I am posting here first...
I am trying to install Pandas using pip, inside a virtual environment on a vanilla remote server running Ubuntu 12.04.3 (64bit). I have already installed the usual suspects (python-dev (2.7), numpy, scipy). Pandas does not get installed and I am not sure exactly what to change or add to ensure this happens.
I have seen other references (not with the same error) implying that memory may be an issue; the remote server (Digital Ocean droplet) only has 512MB.
The tail of the pip error log is shown below:
gcc: internal compiler error: Killed (program cc1)
Please submit a full bug report,
with preprocessed source if appropriate.
See <file:///usr/share/doc/gcc-4.6/README.Bugs> for instructions.

I was having the same problem and error on ubuntu and then created a swapfile and it was solved! A tutorial can be found in the link below but in short:
sudo dd if=/dev/zero of=/swapfile bs=1024 count=524288
sudo chmod 600 /swapfile
sudo mkswap /swapfile
sudo swapon /swapfile
https://www.digitalocean.com/community/articles/how-to-add-swap-on-ubuntu-12-04
After the swap file was created I restarted the server, typed pip install pandas and it finally worked.

The most secure way though is just: sudo apt-get install python-pandas

Probably it's out of memory error. At the top of you log, I can see gcc exit with code error 4. When I google it I saw a stackoverflow thread: Installing lxml with pip in virtualenv Ubuntu 12.10 error: command 'gcc' failed with exit status 4 .
