pip3安装pyautogui失败，错误代码为1 Mac OS

Question

I tried installing the autogui python extension:

pip3 install pyautogui

And this installation attempt results in the following error message:

Collecting pyautogui

    Complete output from command python setup.py egg_info:

My Mac OS version is OS X El Capitan 10.11.3, my Python3 version is 3.5.1, and my pip3 version is pip 8.0.2.

There seems to be a similar question on Stackoverflow ( Cannot install pip install pyautogui, error code 1 ), but the fix does not apply to my problem; I have already installed "pillow". Also, I have read the documentation ( https://pypi.python.org/pypi/PyAutoGUI ), and installed pyobjc-core as well as pyobjc. Setuptools are installed and up-to-date.

Does anyone have an idea how to fix this error (and install pyautogui)? I think the error might originate, because _PyObject_REPR is missing in Python 3.5.1 .

Answer 1

I found a workaround . This code by "Kentzo" fixed the issue for me:

pip3 install https://github.com/GreatFruitOmsk/pyobjc-core/releases/download/v3.0.5.dev0/pyobjc-core-3.0.5.tar.gz

Since the code is not written by me, please use this workaround at your own risk.

Answer 2

SOLVED

Run:

1. sudo pip3 install pil

2. sudo pip3 install Pillow

3. sudo pip3 install pyautogui

Bingo! installed without an error

Answer 3

If you are like me and had no success installing pyautogui, here is what I did to fix the issue:

1. Install Xcode from the Mac App Store. This is a requirement for installing PyObjC. Details can be found here .
2. sudo pip3 install pyobjc-core
3. sudo pip3 install pyobjc
4. sudo pip3 install Pillow
5. sudo pip3 install pyautogui

Steps 2, 3, and 5 are detailed here .

Step 4 is described here , another Stackoverflow post.

Answer 4

The sequence of steps which worked for me on macOS High Sierra(10.13.4) :

• Install Xcode from AppStore

• activate virtual environment (if needed)

• pip3 install pyobjc-core

• pip3 install pyobjc-framework-Quartz

• pip3 install image

• pip3 install pyautogui
