bug in tools\pleft-bootstrap.py (?)

[ghost]

Hi Sander,

I was trying to install pleft on Win7x64. I have Python 2.7 from ActiveState installed and configured and also the PLENV variable. Upon issuing python p:\pleft\tools\pleft-bootstrap.py %PLENV% I get:

Traceback (most recent call last):
  File "tools\pleft-bootstrap.py", line 1512, in <module>
    main()
  File "tools\pleft-bootstrap.py", line 540, in main
    after_install(options, home_dir)
  File "tools\pleft-bootstrap.py", line 1144, in after_install
    subprocess.call([join(home_dir, 'bin', 'pip'), 'install', '--requirement=tools/requirements.txt'])
  File "P:\python27\lib\subprocess.py", line 486, in call
    return Popen(*popenargs, **kwargs).wait()
  File "P:\python27\lib\subprocess.py", line 672, in __init__
    errread, errwrite)
  File "P:\python27\lib\subprocess.py", line 882, in _execute_child
    startupinfo)
WindowsError: [Error 2] The system cannot find the file specified

Looking into p:\pleft\tools\pleft-bootstrap.py#L1143, the path is actually different than the one created in PLENV. There is no bin directory and pip.exe is actually in Scripts. So I changed 'bin' to 'Scripts' to read:

    subprocess.call([join(home_dir, 'Scripts', 'pip'),
                     'install', '--requirement=tools/requirements.txt'])

And re-executing python p:\pleft\tools\pleft-bootstrap.py %PLENV% it starts to download and install the 4 required packages but fails at MySQL-python-1.2.3:

I see that it tries to open the registry key HKLM\SOFTWARE\MySQL AB\MySQL Server 5.0 which does not exist because I have MySQL 5.5 installed (it's also installed from a zip package, and not the .exe installer). I then tried to install mysql-python in my core python 2.7 distribution using pypm to see if it fails in the same way and it did not, it installed just fine:

F:\ProgramData>pypm install mysql-python
The following packages will be installed into "%APPDATA%\Python" (2.7):
 mysql-python-1.2.3
Get: [pypm-free.activestate.com] mysql-python 1.2.3
Installing mysql-python-1.2.3

Any tips? I could install the ancient MySQL 5.0 but if you can think of a way to make it work without that then I think that will be better.

Cheers

Thanks for the bug report! I've never tested this myself in Windows, and clearly some things are not as cross-platform yet as they should be. Patches are welcome.

For now, if you just want to test Pleft, you can remove the mysql-python dependency in tools/requirements.txt. The easiest setup is with SQLite, which is included with Python. This is also the setup used in local_settings.py.debug.
