javascript - Why i cant install "express"? -

-

पहले मैंने इंस्टॉल किया: 

  एलडीएस-मैकबुक-प्रो: ~ ldnwty $ node - संस्करण v0.10.31 एलडीएस-मैकबुक-प्रो: ~ ldnwty $ npm --version 1.4.23 lds-MacBook-Pro: ~ ldnwty $ एक्सप्रेस - संस्करण 4.8.0   
 तब जब मैं मेरी परियोजना में एक्सप्रेस स्थापित करना चाहते हैं:  
  एलडीएस-मैकबुक-प्रो: संपर्क ldnwty $ npm इंस्टॉल एक्सप्रेस एनएमपी वार्न पैकेज.जसन नोड @0.0.0 कोई विवरण नहीं npm वार्न पैकेज.जसन नोड @ 0.0.0 कोई रिपोजिटरी फ़ील्ड नहीं। Express@4.9.6 ../../node_modules/express?a ???? ???? मर्ज- descriptors@0.0.2 एक "????" ????

 और इसके साथ "sudo" भी इंस्टॉल नहीं कर रहा है।  
 क्या यह पहले से ही स्थापित है (विश्व स्तर पर हो सकता है, इसलिए यह आपके ऐप के  <में नहीं है   
 
 node_modules  निर्देशिका), आपको इसे अपने कोड में शामिल करने में सक्षम होना चाहिए:  
  var express = require ('express');   
 यदि आप इसे अपडेट करना चाहते हैं (चूंकि एक नया संस्करण लगता है), तो चलाएं:  
  npm अद्यतन

python - Receiving "KeyError" after decoding json result from url -

-
I am new to Python I am trying to parse JSON result from a URL. Basically, I was using the following: response = urllib.request.urlopen (url) json_obj = json.load (response) It should be a stroke "str 'not' bytes' in the lines of a given" JSON object, so after searching on the StackoverView Flo, I decode the response in this way: F = urllib.request.urlopen (Url) charset = f.info (). Get_param ('charset', 'utf8') data = f.read () decoded = json.loads (data.decode (charset)) If I print "decode" I is as follows: { 'link': { 'summary data': 'https: // localhost / piwebapi / streams / p0_7qHaW4UHU-RlCaz8tpasAAQAAAAU0hJTExNQU42NDIwXFNJTlVTT0lE / summary' 'value': 'https: // localhost / Piwebapi / streams / P0_7qHaW4UHU-RlCaz8tpasAAQAAAAU0hJTExNQU42NDIwXFNJTlVTT0lE / price ',' InterpolatedData ':' https: // localhost / Piwebapi / streams / P0_7qHaW4UHU-RlCaz8tpasAAQAAAAU0hJTE...

.net - Creating a new Queue Manager and Queue in Websphere MQ (using C#) -

-
"itemprop =" text "> I am writing applications that use WebSphere MQ to send messages. My unittests (for flow), I want to verify that I have put the correct message on the response queue. I am trying to figure out how to do this. My main obstacle is that I think it might be scary to clear the queue before running in my queue because the same queue can be used by other applications, I thought a decent solution would be a new line The manager will remove the queue for my solidarity and after using it. So my question is: Is it possible to use C # by using queue manager and queue? After the For future reference and future people, who want to make queues. I thought how to make and remove IBM MQ QE (not quenhers) with PCM messaging. It is not very simple, but it can be done. We have implemented it in a library and it is being used to create and delete commands before and after integration tests. The most important part of the code in this library is shown in the...
