environment-variables

问题 I have a environment variable MY_HOME which has a path to a directory /home/abc Now, I have a redis.conf file In which I need to set this path like this **redis.conf** pidfile $MY_HOME/local/var/pids/redis.pid logfile $MY_HOME/local/var/log/redis.log dir $MY_HOME/local/var/lib/redis/ like we do in command line, so that my config file picks the path based on the Environment variable. 回答1: Because Redis can read its config from stdin , I do something very similar to what @jolestar suggested. I

问题 I am using Python 2.7.11 and am trying to pip install modules however a few of them are failing. The message I get is "Failure to build wheel for 'X'" and "Error: INCLUDE Environment Variable is empty". I tried to install Scrapy, LXML and Twisted and those failed. Some other random modules I tried installed fine. I have installed pyOpenSSL, added python27 and python27/scripts to environment. Thanks, 回答1: I tried both the solutions offered, none worked. I installed Microsoft Visual C++

问题 I've seen different kind of problems around, but I'm fighting with this for a whole day, so please give me some help :) Short story : I have different PATH variable in System Variables panel and cmd. Can't run exe files? Longer story : I'm trying to install Ruby. Tried with different versions, but the problem is the same: I have my PATH value updated, Ruby is there. BUT when using it from cmd, ruby is not recognized. echo %PATH% gives different value from the one in Environment Variables

问题 I have a GNU Makefile (version 3.81) that looks like the following: .PHONY: SPOneDot SPOneDot: ifndef X X=0.05 $$(info X undefined, changed to $X) endif ifndef Y Y=0.05 $$(info Y undefined, changed to $Y) endif python ./Submit3DSP.py -f OneDot.qdt -x $(X) -y $(Y) I execute with the following command line: make X=0.1 Y=0.1 SPOneDot but I get the following result: ifndef X make: ifndef: Command not found make: *** [SPOneDot] Error 127 I've looked in the makefile documentation and seen others

问题 It looks like Ubuntu uses ~/.bashrc , ~/.bash_profile , ~/.pam_profile , /etc/environment , and /etc/profile in very similar ways. I'd like to be able to add a configuration to one of these (which ever is the appropriate one) to set ANT_HOME to be the absolute path to my Ant installation's root directory (happens to be /opt/apache/ant/1.8.4/apache-ant-1.8.4/ ). This variable needs to be "honored" as is any normal env var, where I can open up a terminal and echo it at any time. It would also

问题 I thought maybe it was a system issue but recently did a fresh install (win7 64bit) and a clean install of conemu (had same problem with both conemu and console2 on old win32 system). Also everything I find researching has to do with adding variables via the command line. I'm doing this through Start->Control Panel->System->Advanced System Settings and then restarting the console. cmd picks up the path correctly. When I manually add a new path to the system or user PATH variable and then

问题 In Linux(Ubuntu) I am trying to run a tool and it is showing error "library missing". I don't have permission to install anything in the system (or simply sudo is not possible from my user account). Is it possible to install missing library (libstdc++.so.6 in my case) in my home directory (without sudo) and change the environment-variables etc. so that all other tools/programs can find it? 回答1: Yes, assuming the library is in /home/user/lib . You can set use the LD_LIBRARY_PATH environment
