Thanks for the report! I will see what I can do about this. In the meantime please see #452 (comment).

pip3 install ReText --no-cache-dir is useless.
But I find retext in ~/.local/bin
python3 retext
ModuleNotFoundError: No module named 'PyQt5'
sudo apt-get install python3-pyqt5

Depends: python3 (< 3.6) but 3.6.5-3 is to be installed
Depends: sip-py3api-11.3
E: Unable to correct problems, you have held broken packages.

And then I find icon in ~/.local/share/icons/hicolor/scalable/apps/retext.svg
OS: Deepin 15.11 stable
I think AppImage package is the solution.

[mitya57]

Well, you have broken OS. Deepin 15.11 is based on Debian 9 (stretch), so your version of python3 should be 3.5.3-1 (and I see the same version here). Somehow you have 3.6.5-3. You should fix your system and revert python3 to the OS version.

[sonichy]

sudo apt-get install python3.5
python3.5 is the latest version (3.5.5-1+b1).

sudo apt-get install python3.6
python3.6 is the latest version (3.6.5-9).

And python3.6 is system dependent, can not uninstall.
How to set python-pyqt5 depend python3.5 ?

[mitya57]

Can you please show me the output of apt-cache policy python3?

[sonichy]

apt-cache policy python3

python3:
  已安装：3.6.5-3
  候选： 3.6.5-3
  版本列表：
 *** 3.6.5-3 100
        100 /var/lib/dpkg/status
     3.5.3-1 500
        500 http://packages.deepin.com/deepin lion/main amd64 Packages

[mitya57]

So this confirms my hypothesis. You have installed a package not from repo.

Try this:

sudo apt install --reinstall python3/lion

[sonichy]

Finally, success, thank you !

sudo apt install --reinstall python3/lion
sudo apt install --reinstall python3-pip/lion
pip3 install ReText
    ImportError: No module named 'setuptools'
