pip, pip, pip, ide gyere kiscsirkém!

Meg is lehet csodálni a kérdéses sort:

   130  _PROTOCOL_NAMES = {value: name for name, value in globals().items()
   131                     if name.startswith('PROTOCOL_')
   132                         and name != 'PROTOCOL_SSLv23'}
   133  PROTOCOL_SSLv23 = PROTOCOL_TLS

Amit az interneten találtam, abból megtudtam, hogy nekem egy virtuális environment kellene, azon belül bizonyára jól működne a pip. Hát, nyilván.

2018.10.02. 11:36 Hiszti off, 2.7.15-re frissítve legalább elindul a pip:)

2018.10.02. 11:40 Természetesen nem tud nekem Flaskot telepíteni, de már az is szép tőle, hogy ennyit fáradt vele.

pip is configured with locations that require TLS/SSL, however the ssl module in Python is not available.

2018.10.02. 12:04 Miután elrendeztem a /usr/local/lib/python2.7 és a /usr/local/lib64/python2.7 közötti konfliktust (vagyis mindkettőt töröltem, aztán a kettő egyike szimlink lett a másikra, és megismételtem a fordítást+telepítést), megjavult a derék pip!
Most már csak arra kéne emlékezni, hogy mire is kellett volna ez.
Ja megvan, ezt akartam kipróbálni: https://docs.docker.com/get-started/part2/

Másik számítógép:

Ezen a gépen is ugyanaz volt a gond. Most éppen egy kernel-komponenst akartam fordítani (wireless-regdb), természetesen Python kell hozzá (kicsit furcsállom, hogy nem Comenius Logo vagy MIT Scratch), már adtam neki 'future'-t, meg 'attr'-t, de még van panasza:

Traceback (most recent call last):
  File "./db2bin.py", line 6, in <module>
    from dbparse import DBParser
  File "/usr/local/src/wireless-regdb/dbparse.py", line 35, in <module>
    @attr.s(frozen=True, cmp=False)
AttributeError: 'module' object has no attribute 's'
Makefile:59: recipe for target 'regulatory.bin' failed

2018.10.04 18:11 Igazából 'attrs' kell neki, azzal eljut a 'm2crypto'-ig, az viszont még nem OpenSSL-1.1.1-kompatibilis.
Ezt most egyelőre ennyiben hagyom.
