ruby on rails - Activerecord-PostgreSQL Adapter Error -

-

संभव डुप्लिकेट:

जब "रन डीबी: माइग्रेट" चलते हैं, तो मुझे निम्न त्रुटि मिलती है:

कृपया पोस्टग्रेस्क्ल एडेप्टर स्थापित करें: मणि सक्रिय करें- postgresql-adapter स्थापित करें (dlopen (/ library / ruby /Gems/1.8/gems/pg-0.9.0/lib/pg_ext.bundle, 9): कोई उपयुक्त छवि नहीं मिली। क्या मिला: / लायबरी / रब्बी / गेम्स / 1/8 / ग्राम /pg-0.9.0 / लीब /pg_ext । बंडल: मच-ओ, लेकिन गलत आर्किटेक्चर - / लाइबरी / रबी / गेम्स / 1.8/ ग्राम /pg-0.9.0 / लिब / जीपी_एक्स। बंडल)

  1. पोस्टग्रेस 8.4.4 का उपयोग करके इंस्टॉल किया गया पूर्व निर्मित छवि फ़ाइल।
  2. फिर sudo gem install pg को पीजी-0.9.0 इंस्टॉल करने के लिए चलाया गया
  3. कॉन्फिग / डेटाबेस.इमिल:
    विकास: एडेप्टर: पोस्ट ग्रेसकॉल

क्या किसी को पता है कि समस्या क्या है?

समस्या इस तथ्य से संबंधित है कि मैंने प्रीपेकेज इंस्टॉल PostgreSQL से उपयोग किया है।

python - rename keys in a dictionary -

-
I want to change the names of keys in a dictionary which are ints, and I need them so that the inputs with key zero They can sort correctly. For example, my keys are like this: '1', '101', '11' and I may need them: '001', '101', '011' What is doing, but I know that there is a better way tmpDict = {} in the ADC for the old: t MpDict ['% 04d'% int (olden)] = addict [oldkey] New controlled = tmpDict You are going wrong about this if you want to draw entries on a line in a specific way, then you have to sort on the extraction. for sorted (D, key = int): print '% s:% R'% (k, d [k])

windows - Heroku throws SQLITE3 Read only exception -

After I deploy the app to Heroku, I have to run migration scripts and get this error message ... ITES \ padrino \ prophetmargin & gt; Heroku Rack AR: Rack mutated! SQLite3 :: ReadOnlyException: only one try to write database to read: CREATE TABLE "schema_migrations" ( "version" varchar (255) NOT NULL) /disk1/home/slugs/215264_925fd2c_65a3/mnt/.bundle/gems/gems/ padrino-core- is 0.9.11 / lib / padrino-core / cli / rake.rb: 9: in `init ' how can this be? I also tried to run Heroku dbpush SQLite: //db/my-db.db and that did not work Horoku sqlite3 but using postgres does not do. I'm not sure why you are receiving this error, however, as I have used sqlite3 in development and when pushing it into its travel, they do some magic which migrates to postgrads. I'm absolutely sure how Heroku does 'backwash' this database but it seems that this is happening to you because it's the SQLite db file which is obviously due to Heroku's...

lex - Building a lexical Analyzer in Java -

-
I am currently learning lexical analysis in compiler design. To know how a lexical analyzer actually works, I am trying to build myself. I am planning to make it in Java The input to the lexical analyzer is a .tex file that is of the following format. \ section {script} {intro} \ section {Scope} arbitrary text \ section {relevance} uncontrolled text \ subdivision (profit) arbitrary text \ subsubsection {in real life} \ subdivision {Ingredient} \ end {document} The output of the lecture may be a table of contents with a page number in another file. 1 Introduction 1 1.1 Scope 1 1.2 Relevance 2 1.2.1 Benefits 2 1.2.1.1 Real life 2 1.2.2 loss 3 I hope that This problem is within the scope of Language Analysis Read the .exe file and check '\' and continue to check whether it is actually on search In the sectioning command is set to indicate whether or not a flag variable is the type of sectioning. I hope the above approach will work for the construction of Lexa...
