I have just installed Python 3.4.3 on my MAC (Yosemite). I need to install a couple of lxml, however everytime I type in: pip install /""/, I get error messages.
I have followed multiple tutorials and pip is installed.
MAC already had Python 2.7., but I installed the 3.4.3. version, not sure if that is the issue.
The error message is:
Brunos-MacBook-Pro:~ BrunoPaesLeme$ pip install /Macintosh HD/Users//Downloads/pycairo-1.10.0-cp27-none-win_amd64.whl
Exception:

Anybody knows what I could be doing wrong? Any help would be appreciated.
try:
easy_install pip
pip install /"filepath"/
I have similar issue with pip install. However, if I do "sudo su -" then do my pip install 'fileName', that solve the problem for me.

I recently updated my Homebrew installation of Python 3.8.2 to 3.8.3. After doing so, I ran
$ pip3 install -U pip
in order to check for any pip updates. It updated my installation of pip from 20.0.2 to 20.1.1, and ever since I ran that command, pip throws an error any time I try to use it. Here's the error:

It seems that something went wrong during the upgrade process that failed to change the version check within the code. I saw this similar question, but the accepted answer is not working for me. How can I make pip usable again?
As per Python documentation, the correct way to use pip now would be via the correct Python executable, e.g.
python3 -m pip install -U pip
I had experienced a similar problem on my Ubuntu and here's how I solved my problem:
First restore the older version by reinstalling it from your OS package manager (You may need to uninstall first).
Upgrade to the latest version for your user (as opposed to installing in a system location) with the following command
pip3 install --user -U pip
Hope this helps.
The pip requirements.txt documentation says that extras may be installed using a line like
MyPackage==3.0 [PDF]
So in my requirements.txt file I have a line that reads:
requests==2.9.1 [security]
but instead of installing the security extras for the requests module when I run the command:
pip install -r requirements.txt
I get an error message suggesting that the format of my file is incorrect:
Invalid requirement: 'requests==2.9.1 [security]'

raise RequirementParseError(msg, line, "at", line[p:])
RequirementParseError: Expected ',' or end-of-list in requests==2.9.1 [security] at [security]
Does anyone have any idea what I might be doing wrong?
The correct syntax would be:
requests[security] == 2.9.1
The linked docs seems to be for pip v1.1, while the latest stable version is v8.1. The latest docs for pip are here, but you have to click a few more links to get to the formatting specs for requirements (PEP 0508).
I installed fig on Arch Linux using the following command sudo pip install -U fig. After the installation was completed, I've tried to run fig --version but this gave me following errors:
Traceback (most recent call last):

raise DistributionNotFound(req)
pkg_resources.DistributionNotFound: fig==1.0.1
As it can be seen in the errors, I use python2. I also tried using python3, but I've got the same error.
Can anyone give me a hint?
You can try upgrading pip with easy_install:
easy_install --upgrade pip
Then try reinstalling fig.
I installed fig when python3 with set as default. After setting python2 as default, I've reinstalled fig and everything works now.
I am using the command line to try to install pip. I am using the command line to install the file. I am using the command "python C:\Users\Lucas\Desktop\get-pip.py install" in the C:\Python27 directory. Below is the error message i receive in the error log:

python get-pip.py
Do not pass any parameters:

or

Try this out
sudo python get-pip.py
Try doing all these activities using python3 and pip3. That worked for me

I am using Canopy Express and this package is provided (see this)..
I have tried to install it from pip but, since I have not administration permissions, I am unable to install it..
Edit: the same happens with Pygments package when installing ipython:
appinst-2.1.2-1.egg [fetching]
55 KB [.................................................................]
MarkupSafe-0.18-2.egg [fetching]
26 KB [.................................................................]

Thanks
a few of our free packages had been flagged as "commercial" by mistake. We fixed the problem and you should be able to install them now.
Sorry about the trouble!
