Error: zsh: command not found: pip mac m1 - python

When I try to install LDFLAGS=-L/usr/local/opt/openssl/lib pip install mysql-python I get this error:
zsh: command not found: pip
who faced such problem?


maybe it will help someone in the future. I solved this issue in the following way for mac m1:
export PATH=/opt/homebrew/bin:$PATH
brew install python
easy_install pip
Then you need to make sure that pip has installed:
pip3 --version
in my case it installed:
pip 22.3.1 from /opt/homebrew/lib/python3.11/site-packages/pip (python 3.11)
And then you can install dependencies!

pip version warning in Python but terminal version is showing latest version

I am receiving the following warning when I install a package through pip in Python:
WARNING: You are using pip version 20.0.2; however, version 22.2.2 is available.
You should consider upgrading via the 'C:\Users\wildman\Anaconda3\python.exe -m pip install --upgrade pip' command.
However, when I run the pip --version command in terminal, it is saying:
pip 22.2.2
Can somebody please provide some pointers on resolving this?
Cheers.

the warning says pip in conda environment.
C:\Users\wildman\Anaconda3\python.exe -m pip
check your that pip using this command :
C:\Users\wildman\Anaconda3\python.exe -m pip --version
maybe if you directly pip --version, it direct to another python environment

How do I upgrade from pip 1.0?

I was trying to install a package which required an older version of pip and (stupidly) thought it would be a good idea to try installing the oldest version of pip possible (1.0).
To clarify, it is not pip 1.0.1 (which most guides I found on the internet refer to), but pip 1.0
When I attempt to run 'python -m pip install --upgrade pip', I get the following error:
C:\mydirectory\venv\Scripts\python.exe: No module named pip.__main__; 'pip' is a package and cannot be directly executed
When I run 'pip --version', I get the following info:
pip 1.0 from c:\mydirectory\venv\lib\site-packages (python 3.7)
Is there any way I can upgrade pip from this point?

python -m pip install -U pip should work. That is how I do it.

Try this:
python3 -m pip install pip

ERROR: Could not build wheels for cryptography which use PEP 517 and cannot be installed directly

I get an error when pip builds wheels for the cryptography package.
Error:
LINK : fatal error LNK1181: cannot open input file 'libssl.lib'
error: command 'C:\\Program Files (x86)\\Microsoft Visual Studio\\2017\\BuildTools\\VC\\Tools\\MSVC\\14.16.27023\\bin\\HostX86\\x86\\link.exe' failed with exit status 1181

ERROR: Failed building wheel for cryptography

Failed to build cryptography
ERROR: Could not build wheels for cryptography which use PEP 517 and cannot be installed directly
I have already installed OpenSSL and set the environment variables as suggested in this post yet the problem persists. My setup details:
System - Windows 10
Python - 3.8
Pip - 19.3.1

In my case (windows 10 + conda) updating pip fixed the problem:
python -m pip install --upgrade pip

Setting cryptography to version 2.8 in requirements.txt fixed the issue.

TLDR;
Try using cryptography==3.1.1
Details:
This happened on Python 3.9.0 on Windows 10 PC.
I had the following in requirements.txt
cryptography==2.8
I removed the version and kept only cryptography in requirements.txt file like below
cryptography
Saved the requirements.txt and then I ran
pip install -r requirements.txt
It installed successfully.
Then I freeze the requirements.txt by running the following command
pip freeze > requirements.txt
Then the requirements.txt got updated with cryptography==3.1.1

Had also this issue. If you're using alpine, make sure that all dependencies for cryptography are installed.
In my case the cargo package was missing and causing the issue.
sudo apk add gcc musl-dev python3-dev libffi-dev openssl-dev cargo
https://cryptography.io/en/latest/installation.html#building-cryptography-on-linux

Ran into this issue, and the solution is actually in the message when pip attempts to install openssl before cryptography:
generating cffi module 'build/temp.linux-x86_64-3.7/_openssl.c'
running build_rust
=============================DEBUG ASSISTANCE=============================
If you are seeing a compilation error please try the following steps to
successfully install cryptography:
1) Upgrade to the latest pip and try again. This will fix errors for most
users. See: https://pip.pypa.io/en/stable/installing/#upgrading-pip
2) Read https://cryptography.io/en/latest/installation.html for specific
instructions for your platform.
3) Check our frequently asked questions for more information:
https://cryptography.io/en/latest/faq.html
4) Ensure you have a recent Rust toolchain installed:
https://cryptography.io/en/latest/installation.html#rust
5) If you are experiencing issues with Rust for *this release only* you may
set the environment variable `CRYPTOGRAPHY_DONT_BUILD_RUST=1`.
=============================DEBUG ASSISTANCE=============================
Simply running the pip update command appeared to work for me:
pip install -U pip
Which updated pip from version 18.0 to version 21.0.1

I faced this issue on macOS Monterey (version 12.2.1) Apple M1 Pro. I followed Cryptography installation documentation and it helped me resolve the issue.
brew install openssl#1.1 rust
env CRYPTOGRAPHY_SUPPRESS_LINK_FLAGS=1 LDFLAGS="$(brew --prefix openssl#1.1)/lib/libssl.a $(brew --prefix openssl#1.1)/lib/libcrypto.a" CFLAGS="-I$(brew --prefix openssl#1.1)/include" pip3 install cryptography

You can use the lastest version with
python3 -m pip install --no-use-pep517 cryptography
worked for me with ubuntu:18.04 on arm32v7
(instead as suggested by the error message install the full rust compiler and build-essentials, or upgrading pip (what had no effect on ubuntu:18.04 on my armbian))

pip install --upgrade pip
Try to upgrade pip of your environment working fine for me.

I got this error trying to install Scrapy with Python 3.8.1 on Windows 10, but its solved installing the last version of pip (19.3.1 in my case) and all works using pip in this way:
python -m pip install scrapy --user

I have faced same issue and tried to install openssl with mentioned step but still was not able to proceed for windows 10. Later I upgraded pip to latest version and tried again and it worked without any issue.
I would recommend to upgrade pip to latest version and give a try before proceeding for installing openssl

I had the same issue. pip3 version was 19.* after upgrade it works
sudo -H pip3 install --upgrade pip

You can try to install cryptography==3.1.1 package instead of cryptography 35 version.
pip install cryptography==3.1.1
If still you are facing challenges in cryptography package integration.
You can resolve that by the following steps.
python -m pip install --upgrade pip
sudo pip install -U pip setuptools

I had this problem and i just installed rust and problem fixed for me
You can install end version of cryptography after installing rust programming languege(dont try pip install rust, its not python package)
https://www.rust-lang.org/tools/install

Just updating pip
python -m pip install --upgrade pip

I did not install the latest version of Scrapy, then it worked for me. Instead of installing version 2.6.3, I installed 2.6.2:
pip install Scrapy==2.6.2
I use PyCharm 2022.2.3 (Professional Edition) on Windows.

Cannot run pip/pip3 command OS X

When trying to install scikit-learn I encountered an error:
$ pip3 install scikit-learn
-bash: pip3: command not found here
$ pip install scikit-learn
-bash: pip3.4: command not found
How do I resolve this? I've already tried uninstalling pip and reinstalling it via python3, but nothing seems to work.
Pip3, however, does still seem to be installed on my machine:
$ locate pip3
/opt/local/var/macports/sources/rsync.macports.org/release/tarballs/ports/python/py-pip/files/pip33
/opt/local/var/macports/sources/rsync.macports.org/release/tarballs/ports/python/py-pip/files/pip34

/usr/local/Cellar/python3/3.4.3/bin/pip3.4
/usr/local/Cellar/python3/3.5.0/bin/pip3

Pip install results in error "no such option: -E"

I just cleaned up my mac after a mavericks install (yeah, i'm late to the party).
I'm using homebrew Python but I've confirmed this error with the stock apple python as well. I've got pip 1.5.6 installed system-wide and also in my virtualenv.
I can pip-sys install for system-wide pip installs no problem. When In a virtualenv though, I get the following error, even with which pip.
pip install -U -r requirements/dev.pip
Usage:
pip <command> [options]
no such option: -E

Seems there is something wrong with the pip install within the virtualenv. Pip is not working but pip2 install works fine. So maybe there's a version conflict where pip installs thinking it's a different python version from what was installed.
To recap
pip install south
fails with above error
pip2 install south
works fine.
