Trouble on re-installing Ruby from scratch

阅读更多关于 Trouble on re-installing Ruby from scratch

问题 I am using rvm (Ruby Version Manager) and I deleted some gems by running the gem update --system command. I had some serious problem so I decided to reinstall rvm and ruby 1.9.2 on my local machine (MacOS Snow Leopard 10.6.7). Now, if I run the rails s command I get the following $ rails s /Library/Ruby/Site/1.8/rubygems.rb:779:in `report_activate_error': Could not find RubyGem rails (>= 0) (Gem::LoadError) from /Library/Ruby/Site/1.8/rubygems.rb:214:in `activate' from /Library/Ruby/Site/1.8

Rbenv not rehashing correctly and making shims

阅读更多关于 Rbenv not rehashing correctly and making shims

问题 The bottom line is, rbenv isn't making shims. I've exhausted ideas of what could be the problem. After a few days of banging my head against a wall to fix but no avail, I think it's time to ask for help. I'm attempting to make the switch from RVM to rbenv, so that could obviously be a factor here. Any ideas/help would be great. Here's what happens: [09:38] ~ $ gem install pry Fetching: pry-0.10.2.gem (100%) Successfully installed pry-0.10.2 1 gem installed [09:39] ~ $ rbenv rehash [09:40] ~ $

如何以CSV格式输出MySQL查询结果？

阅读更多关于如何以CSV格式输出MySQL查询结果？

【推荐】2019 Java 开发者跳槽指南.pdf(吐血整理) >>> 有没有一种简单的方法可以从Linux命令行运行MySQL查询并以 CSV 格式输出结果？这是我现在正在做的事情： mysql -u uid -ppwd -D dbname << EOQ | sed -e 's/ /,/g' | tee list.csv select id, concat("\"",name,"\"") as name from students EOQ 当有很多列需要用引号引起来时，或者结果中有引号需要转义时，它将变得混乱。 #1楼 MySQL Workbench 可以将记录集导出为CSV，并且似乎可以很好地处理字段中的逗号。 CSV在OpenOffice中可以正常打开。 #2楼仅限于Unix / Cygwin ，将其通过'tr'传递： mysql <database> -e "<query here>" | tr '\t' ',' > data.csv 注意：这既不处理嵌入式逗号，也不处理嵌入式制表符。 #3楼 mysql --batch，-B 使用tab作为列分隔符打印结果，每一行都换行。使用该选项，mysql不使用历史文件。批处理模式导致以非表格格式输出格式并转义特殊字符。可以通过使用原始模式来禁用转义。请参阅--raw选项的说明。这将为您提供一个制表符分隔的文件。

问题 I am going through the motions to understanding the Omega 4 Theme in drupal. I did the sub-theme through drush and I have rvm, ruby and I believe all the gems installed. I should add that I have rgbapng & compass installed. I am not familiar with the @global though...

问题 I am using: TextMate: version 2.0-alpha.9511 rvm: 1.25.15 (stable) ruby: version 2.1.0p0 oh-my-zshell: 5.0.2 Mac OS X: 10.9.1 (Mavericks) I have rvm and textmate set up to use TM_RUBY=/Users/<myuser>/.rvm/bin/rvm-auto-ruby The problem: when I try to run my rake tasks using the rake bundle in textmate, I get some errors about the file not loading: "cannot load such file -- rubocop/rake_task" The clue: I changed my rakefile so that it simply reports the "gem env" for the default task.

RVM cannot build OpenSSL on Mountain Lion

阅读更多关于 RVM cannot build OpenSSL on Mountain Lion

问题 Ruby will build just fine, but it won't build with OpenSSL support. I've tried setting CC to point to both the XCode 4.6 command line tools' copy of GCC and MacPorts' version of gcc 4.2. That doesn't work. I've added --with-openssl-dir=$rvm_path/usr and --with-opt-dir=$rvm_path/usr . Neither of those work. Each time it fails, I check the log and it just says that there was an error configuring OpenSSL and that it will be skipped. Any ideas? 回答1: I had the same issue recently after installing
