path

问题 On git bash , I receive a command not found message for python , r and nano . I am on Windows 10. I do not know what I am doing wrong. I type r --version python --version nano --version and they all return command not found . I read something that had me try alias python='winpty python.exe' and it renamed python , but when I tried touch .bashrc it returned touch: command not found I followed the instructions in a Github course, PS239T. I have been fortunate, except for getting these three

问题 Suppose you have a path like so: $myPath = 'C:\Python\27' Is there a more reliable in PowerShell way of converting that path to Unix format than just replacing the \ s like this? PS C:\> $myPath -replace '\\','/' C:/Python/27 回答1: That's the way I would do it, I'm not familiar with any other (built-in) way. 来源： https://stackoverflow.com/questions/17036140/convert-windows-formatted-path-to-unix-style

问题 I have a couple of Applications added under my Default Website in IIS8.5 (simply http on port 80 IP=*) They point to different physical paths (which are not nested) and this works fine after adding such an application. But after a while the Physical Path of one of the applications automagically changes to the physical path of another Application. Why? I have flushed my DNSCache and removed and added the Application once again, but something is changing the physical path of my configuration.

问题 Task I'm looking for an universal way to get the (absolute) root path of an installed npm package in Node.js. Problem I know about require.resolve , but that will give me the entry point (path to the main module) rather than the root path of the package. Take bootstrap-sass as an example. Say it's installed locally in a project folder C:\dev\my-project . Then what I'm looking for is C:\dev\my-project\node_modules\bootstrap-sass . require.resolve('bootstrap-sass') will return C:\dev\my-project

问题 I am using HaskellPlatform-2012.4.0.0 on Win7. It's installed as portable. Paths are managed through .bat file so ghci and ghc works. But cabal installs it self at C:\Users\name\AppData\Roaming\cabal\ To circumvent that I did: cabal update edit config file delete all files except config Changed paths: remote-repo-cache: d:\h1\cabal\packages world-file: d:\h1\cabal\world build-summary: d:\h1\cabal\logs\build.log It works, but it's far from truly portable. Cabal config is bigger problem. It

问题 I recently installed Erlang RFC4627 (JSON-RPC) with the debian package. I ran the test server using: sudo erl -pa ebin and then at the prompt: test_jsonrpc:start_httpd(). returned ok I tested with http://:5671/ and got the success messages. When I try to run rabbitmq-http2 however, I get the errors that the readme says are caused by rfc4627's code not being on the erlang search path. How do I put it on the path. I saw something on Dave Thomas's blog which suggested putting the path in the

问题 I tried to include the following unsuccessfully to my ~/.profile: export PATH='$HOME/opt/git/bin' It seems not to work because $git gives me nothing. I am trying to install Git. I have also tried commands here. 回答1: You'll want to be careful with that command. It will override your $PATH. You might need to put it in ~/.bash_profile and change it to this: export PATH="$HOME/opt/git/bin:$PATH" 回答2: As SirLancelot pointed out, you reset your path rather than augmenting it. You also used single
