PyInstaller failing to install through pip

Question

pip 19.0.1 from c:\\users\\halzein\\appdata\\local\\programs\\python\\python37\\lib\\site-packages\\pip (python 3.7)

Trying to install PyInstaller with this command:

pip3 install PyInstaller --trusted-host pypi.org --trusted-host files.pythonhosted.org

(I get errors if I try to use pip without trusted-host tags)

And the install keeps failing due to this error after downloading and installing build dependencies:

ModuleNotFoundError: No module named 'PyInstaller'

---

Command "c:\\users\\halzein\\appdata\\local\\programs\\python\\python37\\python.exe c:\\users\\halzein\\appdata\\local\\programs\\python\\python37\\lib\\site-packages\\pip\\_vendor\\pep517\\_in_process.py get_requires_for_build_wheel C:\\Users\\halzein\\AppData\\Local\\Temp\\tmpfwtrnagf" failed with error code 1 in C:\\Users\\halzein\\AppData\\Local\\Temp\\pip-install-thcvcr0q\\PyInstaller\\

Not really sure what's causing this, and my searches have come up with nothing.

Answer 1

I faced same error, here's what worked for me:

Run windows powershell as administrator, and downgrade pip to 18.1 by typing pip install pip==18.1 this will uninstall 19.0.1 and install 18.1 version. After that just run pip install pyinstaller and it should finish it with no errors. Than you can upgrade pip to 19.0.1 with python -m pip install –upgrade pip

Hope this help you too.

Cheers =)
