Any ideas? * * * * * Rscript “/Users/Home/Desktop/David Studios/Scraper/compiler.R” Also, this was working as just a normal command in Terminal. 回答1: I can see the dreaded smart quotes in your cron entry. This often happens when you copy-paste from word processors. Backspace over those abominations and re-type normal quotes. Change: * * * * * Rscript “

问题 RESOLVED: Installing Xcode on my Mac installed all missing dependencies of Matplotlib, thus I was able to successfully install Matplotlib via Terminal. I currently have Python 2.7 and Python 3.8 (downloaded the .dmg via Python.org) on my Mac OS X Catalina. I have successfully installed Numpy via Terminal, as well as Matplotlib on Python 2.7 via Terminal, but I always get two error codes when I install Matplotlib through Terminal. I've tried using different variants of inputs via terminal via

问题 When I open the terminal in android studio and type, nothing registers and the cursor stays put. The screen shot caught the cursor between flashes but it stays right by the > after app. Someone else had the same issue 4 months ago here : Android Studio terminal issue But no one came forward with solutions. Anyone know how to fix this? 回答1: This behavior is a problem related to an incompatibility between IntelliJ (and then Android Studio) and the new windows 10 console (https://youtrack

问题 I'm specifically looking for a solution for PuTTY but also interested for other terminal emulators, like Gnome Terminal. My thought is it would be useful if I start a tar zxvf to be able to set a trigger on the terminal emulator, minimize it, and on next output to stdout/stderr I get a notification in the task bar that the command has finished. 回答1: This works for me: echo -e "\a" Then update your PuTTY session to use the Visual Bell, and set "Taskbar/caption indication on bell" to Flashing

问题 Modern API for Logging is easy configurable in Terminal. However, Xcode seems to output all levels including INFO and DEBUG which is very annoying. Because most of the time you want to see only os_log_error and NSLog aka “something went wrong” and “this is important”. So is there any way to display only particular levels in Xcode Console? os_log_info(OS_LOG_DEFAULT, "Info"); os_log_debug(OS_LOG_DEFAULT, "Debug"); os_log_error(OS_LOG_DEFAULT, "Error"); os_log_fault(OS_LOG_DEFAULT, "Fault"); os

问题 I am trying to do something rather simple, but don't understand why I am getting an error. I have a Makefile I will include so you can see what is going on. But when I step through the program I get libc-start.c: No such file or directory . Is there a way to handle this in the Makefile or avoid this? Makefile # makefile to build a program # program depends on components: name and main myname: main.o name.o g++ -g -ggdb main.o name.o -o myname # name.cpp has it's own header file name.o: name

问题 After installing Homebrew using the script on their homepage and checking if everything was alright with brew doctor , I issued brew install python3 in order to install Python 3 on my Mac. Everything seemed fine until I tried running python3 --version ; I ended up getting: -bash: /Library/Frameworks/Python.framework/Versions/3.5/bin/python3: No such file or directory I checked in the file directory to see what was going on and indeed, I didn't see any files pertaining to Python in my

问题 I want to write a program that can be run as a backgrounded task (i.e. my-thing & ), and that will beautifully provide relevant output when necessary. However, with background tasks that print to the terminal, there's always this annoying little progression: bash-3.2$ my-thing & ▏ bash-3.2$ my-thing & bash-3.2$ -- Hello from my-thing! -- now let me start doing what I do best ... ▏ … notice that we now have no prompt before the cursor, not to mention that there's an ugly erraneous prompt where
