env: python: No such file or directory when building app with Xcode

Question 1

When I build/run/archive my app in Xcode (on MacOS 12.3) I encounter this error:

env: python: No such file or directory
Command Ld failed with a nonzero exit code

I think I might have changed something with regard to my python environment while working on a school project or messed something up there. However, I can not figure out what is wrong.

I tried reinstalling Xcode and python (using brew and pyenv). I also relinked python using brew. But I still encounter the same error.

Which python gives the following results:

which python3
-> /usr/local/bin/python3

And in my ~/.zshrc I have the following line:

export PATH=/usr/local/bin:/usr/local/sbin:~/bin:$PATH

Any help would be appreciated! If I missed or forgot anything please let me know, I'm quite new to this.

Question 2

Are you sure that what's in .zshrc affects Xcode? I don't know, but I would not bet on it, as Xcode is not normally launched from a shell.

Question 3

Yes I don't think that should matter. However I added it as I'm quite new and normally I run the NativeScript project in the terminal (which uses Xcode), so I thought that might be affected by it. But indeed, also running it in Xcode also triggers this error.

Question 4

Homebrew only installs the binary python3, just to be safe. Xcode is complaining about a lack of the binary python (note the lack of a 3!).

You have a couple of options:

When installing python3, Homebrew also creates a libexec folder with unversioned symlinks, such as python (what you're missing). Note the Caveats printed when installing it:

$ brew info python
[email protected]: stable 3.9.10 (bottled)
==> Caveats
Python has been installed as
 /opt/homebrew/bin/python3
Unversioned symlinks `python`, `python-config`, `pip` etc. pointing to
`python3`, `python3-config`, `pip3` etc., respectively, have been installed into
 /opt/homebrew/opt/[email protected]/libexec/bin
See: https://docs.brew.sh/Homebrew-and-Python

You could add this directory to your $PATH, such that python and pip become available; something like the following might suffice:

echo 'export PATH="'"$(brew --prefix)"'/opt/[email protected]/libexec/bin:$PATH"' \
 >>~/.bash_profile

... although that will need to be modified according to your precise version of Python3, your shell of choice, etc.

Alternatively and more simply, although a little more jankily, you could simply manually create the appropriate symlinks:
```
ln -s "$(brew --prefix)/bin/python"{3,}
```

Question 5

Can't work on MacBook Air m1. Please refer to github.com/bazelbuild/bazel/issues/15510

Question 6

Awesome, #1 didn't work for me even though I have 3.9, but #2 did.

Question 7

@劉大為 I'm not sure what you mean — the above works precisely as it's supposed to on an M1; that's what I'm typing on, right now. That's why the snippets use brew --prefix, in fact. That said, modifying $PATH is difficult to explain predictably; there's lots and lots of variance on different systems as to how the final value comes into existence — if it didn't work, I suggest you dive into debugging your $PATH settings.

Question 8

I've been stuck for few hours until I ran the above command. Worked great on M1 macbook pro.

Question 9

second alternative works

Question 10

Add -f to be effective.

ln -s -f /usr/local/bin/python3 /usr/local/bin/python

Your answer could be improved with additional supporting information. Please edit to add further details, such as citations or documentation, so that others can confirm that your answer is correct. You can find more information on how to write good answers in the help center.

Question 12

this worked, be sure to add 'sudo' before this command if you're in macOS monterey

Question 13

worked for me without sudo!

Question 14

Doesn't seem to work with Sequoia (Python3 came preinstalled). The -f makes the command run without error, but it doesn't have an effect even after restarting the terminal. In the end I just downloaded the installer directly from the website and installed it fresh. Didn't need to uninstall the old version, seems like it was removed automatically. Now the python and python3 commands both link to 3.13.1

Question 15

I had posted the same question on nativescript official github and the solution that worked for me was in the answer by the user shilik

Monterey 12.3 removes python 2. All you need to do is to reinstall python2 back to system from this link https://www.python.org/downloads/release/python-2718/

Question 16

@aaossa I have removed the "question part" of my previous post: was intended to give only a little bit of (my) context to the original question because I think that was the same problem. Now I left only the answer, did you mean this in your comment?

Question 17

Upgrading to Monterey messed me up too. This is what I did... 1) Install pyenv with brew install pyenv 2) Install Python 2.7 with pyenv install 2.7.18 and then pyenv global 2.7.18 3) Then set the default paths typing in the console export PATH="${HOME}/.pyenv/shims:${PATH}"

Question 18

Tried all answers on this page, and this was the only one that worked. Thanks

Question 19

Install python3
Run ln -s /usr/bin/python3 /usr/local/bin/python, which creates a symbolic link (shortcut) from /usr/local/bin/python to /usr/bin/python3 - it means when you run python in the terminal, it will execute /usr/bin/python3

Question 20

Your answer could be improved with additional supporting information. Please edit to add further details, such as citations or documentation, so that others can confirm that your answer is correct. You can find more information on how to write good answers in the help center.

Question 21

Worked for me on Monterey! ln -s /usr/bin/python3 /usr/local/bin/python

Question 22

@bibo bode - this gives me 'Permission denied'

Question 23

You may have to use sudo before the command @Robbie

Question 24

For me the problem was with missing python env: python: No such file or directory

BUT in the end missing was python version 2.x after updating to macOS Monterey 12.5 (21G72). Problem was resolved by installing python from: https://www.python.org/downloads/release/python-2718/

What I've also tried but you probably don't have to do:

sudo brew install python
sudo brew upgrade
sudo ln -s -f /usr/local/bin/python3 /usr/local/bin/python
sudo ln -s $(which python3) /usr/local/bin/python
sudo ln -s $(which python3) /Applications/Xcode.app/Contents/Developer/usr/bin/python
sudo ln -s /Applications/Xcode.app/Contents/Developer/usr/bin/python3 /Applications/Xcode.app/Contents/Developer/usr/bin/python

Question 25

Thanks! "sudo ln -s $(which python3) /usr/local/bin/python" helped me

Question 26

This took me days of head scratching, and none of the solutions I found on the internet worked.

Eventually what DID work for me was this:

sudo ln -s /Applications/Xcode.app/Contents/Developer/usr/bin/python3 /Applications/Xcode.app/Contents/Developer/usr/bin/python

I used the find command to find all instances of python in the file hierarchy:

find / -name python*

and I saw that there was a symbolic link labelled python3 in /Applications/Xcode.app/Contents/Developer/usr/bin/ that was linked to a python instance deep within the bowels of Xcode.

However there was no symbolic link labelled python which seems to be what Xcode is looking for.

So I created a symbolic link linking python to python3 and that did the trick.

For what it's worth, I installed python via pyenv which I installed through homebrew on a 2020 Mac mini M1.

Question 27

I was able to solve this issue with the above-mentioned answers.

In my case, while I was trying npm install in my node project and was facing this issue.

Note: % brew install python is a prerequisite for all the below steps! Test if python is correctly installed by brew info python

First thing which comes to mind is if python is correctly installed and the path is set correctly.

python --version was giving zsh - python not found error while python3 --version was a success.

Next steps were to set the correct path. I did the below steps and it worked:

echo "alias python=/usr/bin/python3" >> ~/.zshrc

ln -s -f "$(brew --prefix)/bin/python"{3,}

ln -s -f "$(which python3)"{3,}

What I was missing was to run brew install python, and it worked like a charm!

Question 28

In my case, created symbolic link for dev_appserver.py like below.

ln -s /opt/local/bin/python2.7 /usr/local/bin/python
ln -s /opt/local/bin/python2.7 /usr/local/bin/python2

Command location and version should be adapted to your environment.

Question 29

Please install Python through https://www.python.org/downloads/ or https://www.python.org/ftp/python/3.13.3/python-3.13.3-macos11.pkg, despite your existing Python version.

I had Python 3 on my Mac (I had used brew install python earlier). Now I have again installed Python using the above URL, and after I ran the below command (refer https://docs.aws.amazon.com/cli/v1/userguide/install-macos.html#install-macosos-bundled-sudo) and successfully installed

sudo ./awscli-bundle/install -i /usr/local/aws -b /usr/local/bin/aws
