The back-end debugger about Eric 6 cannot start error [the Debugger backend could not be started]

Statement:

1) This article is written by my Bitpeach original. If you have reproduced this article, please specify the source.

2) This article is mainly about Eric6 a strange mistake. Because the length is not long, just a short note, in case of file inspection.

1.1 Software Environment

(1) EIRC6, version number: 6.0.5

(2) PyQt4.11.3

(3) Python2.7.3

(4) Windows7

1.2 Error types

(1) Back-end debugger failed to start error

(2) The English description is: The Debugger backend could not be started

1.3 Error Research

(1) After Baidu, similar results basically did not, so did not find the reason

(2) After Google, found that there are similar results, the site is: https://riverbankcomputing.com/pipermail/eric/2011-March/002964.html

But there is no solution, just a few macro ideas

1.4 Error Causes and remediation methods

(1) According to the above Google's post, has been points out some ideas, but may be some of the terminology is not correct. It is not the firewall that masks the configuration connection, but the administrator rights, because the lack of administrator rights to install ERIC6 prevents the backend from starting. There is a phenomenon can confirm my statement, the use of administrator rights and non-administrator rights, the installation of Eric6,eric6.bat this startup program location path is different, interested can use different permissions to try.

(2) Correction method:

Error procedure : in the blank space of the file manager, the mouse clicks the blank place, then shift+ right mouse, launches the Python, to the ERIC6 directory, uses the command Python install.py install.

Cause of error: shift+ Right-start is not administrator rights.

Correction Method : If it is Win7, from the menu cmd input, need administrator privileges to start, if it is win8 or win10, right mouse click on the bottom left menu icon, pop up the right-click menu, select Command Prompt (Administrator rights).

Go to the ERIC6 directory and use the command Python install.py install later, as described earlier

1.5 Other issues during the Chinese

(1) The author has personally tested, ERIC6 version number 6.0.5 will appear the following error, but the version number Eric 6.1.3 did not appear the following error.

(2) Problem type: In the case of Eric version number 6.0.5, when installing install-18n.py this Chinese script, the import PyQt5 error is reported.

(3) Correction method, the install-18n.py this Chinese script, the 19th line "from Pyqt5.qtcore import Qdir" to "from Pyqt4.qtcore import Qdir"

(3) The author's question: Eric6 may be designed for PYQT5, so the above errors may be caused by the author himself. Interestingly, after this correction, ERIC6 can be used for PYQT4, which means Eric6 can be used for both PYQT4 and 5.

It is worth mentioning that no similar error has occurred in Eric6.1.3.
