I messed up my PATH and expo no longer recognises Xcode being installed. I know that it is because of the PATH and I tried most of the suggestions here on Stack and the problem got worse.
Firstly, every time I open a terminal I am prompted with these messages:
Last login: Wed Feb 15 19:25:08 on ttys001
/etc/zshrc:7: command not found: locale
/etc/zshrc_Apple_Terminal:104: command not found: mkdir
When I write which expo I am prompted with /opt/homebrew/bin/expo.
When I write which Xcode I am prompted with xcode not found. :(
When I type echo $PATH I am prompted with all this:
/opt/homebrew/bin:/opt/homebrew/sbin:export HOMEBREW_PREFIX="/opt/homebrew";
export HOMEBREW_CELLAR="/opt/homebrew/Cellar";
export HOMEBREW_REPOSITORY="/opt/homebrew";
export PATH="/opt/homebrew/bin:/opt/homebrew/sbin${PATH+:$PATH}";
export MANPATH="/opt/homebrew/share/man${MANPATH+:$MANPATH}:";
export INFOPATH="/opt/homebrew/share/info:${INFOPATH:-}";
As the initial problem was with (AWS) amplify pull command not being recognised, I followed the steps in this thread to write on the .zprofile so I typed :
2. vim .zprofile
3. Press i, then paste this line
export PATH="$HOME/.amplify/bin:$PATH"
4. Press Esc and :wq to save this file
Then I changed stuff again following this thread and I understand now how to add export PATH=/opt/homebrew/bin/ but it disappears when I close the terminal.
Also, neither vim nor ls are recognised commands.
Question 1:
Is there a way to restore my system variables and PATH to a default?
Question 2:
How could I change my path for expo to see the application installed and run the simulator?
Question 3:
How do I make it permanent/save it?
I would be forever grateful for any support, because there has been 2 days of frustration now.. :((
Please help!
I have looked at a lot of answers on here and I'm still not able to figure this one out. I am attempting to learn node again, but after my global install of nodemon (which completed successfully) I am getting command not found: nodemon when running nodemon app.js. A while back I moved my npm path to /Users/mlefkowi/npm-global for some reason. When I echo $PATH, that directory does not exists. This is what I get:
/Library/Frameworks/Python.framework/Versions/3.4/bin:/Library/Frameworks/Python.framework/Versions/2.7/bin:/usr/local/bin:/usr/bin:/bin:/usr/sbin:/sbin
I have been able to add it to the $PATH, but when I close out Terminal it doesn't save. Should I move npm back to it's default directory? How can I get a path to save to $PATH?
Edit your ~/.bashrc and add the following line:
export PATH="/Users/mlefkowi/npm-global:$PATH"
This assumes that /Users/mlefkowi/npm-global/nodemon is the path to the nodemon executable. If it's in a bin sub-directory off of npm-global, then change /Users/mlefkowi/npm-global to /Users/mlefkowi/npm-global/bin.
.bashrc is sourced every time your shell starts up, so this modification will stick for all new terminal sessions. After editing it for the first time, run source ~/.bashrc to update your PATH for that session.
I am having an issue with tab-completion that I am unable to solve. Specifically, whenever I try to tab-complete a directory, the completed directory name appears with a space following it instead of a forward slash to complete the rest. for example
~$ python ~/sof
tab-completes to
~$ python ~/software<space>
Instead of
~$ python ~/software/
Interestingly this does not happen with cd but with everything else it does.
Apparently it is a known bug. Deleting /etc/bash_completion.d/acroread.sh solved the issue.
I recently reinstalled Cygwin on my computer in order to get access to several command line elements that I was missing. I have never had previous difficulty with Cygwin, but after this reinstallation, an error message continues to appear after (almost) each command entered. For instance:
-bash-4.1$ wc m1.txt
3 [main] bash 2216 child_info_fork::abort: data segment start: parent(0x26D000) != child(0x38D000)
-bash: fork: retry: Resource temporarily unavailable
2013930 4027950 74968256 m1.txt
Generally, the command still runs (as seen above), but not always. Occasionally, the 'error' message occurs several times in a row (the initial number "3" will then change to a "4" or "2", notably if I start a second Cygwin window.
Also, as soon as I start up Cygwin, I get the following message before the prompt:
3 [main] bash 6140 child_info_fork::abort: data segment start: parent(0x26D000) != child(0x36D000)
-bash: fork: retry: Resource temporarily unavailable
-bash: fork: Resource temporarily unavailable
-bash-4.1$
At the moment, I am debating whether to uninstall/reinstall Cygwin again or just live with the error messages, but I was curious if there might be an issue that I am unaware of.
(assuming Cygwin is installed at C:\Cygwin):
Open Task Manager and close any processes that look to be Cygwin related.
Open C:\Cygwin\bin in Windows Explorer
Verify that dash.exe, ash.exe, rebase.exe, and rebaseall exist in this folder
If any of them are missing, re-run Cygwin setup and select the dash, ash, and rebase packages
right-click your C:\Cygwin folder, uncheck Read-only (if its checked), and press OK.
When an error about not being able to switch some files comes up, select "Ignore All". Wait for this process to complete.
Browse to C:\Cygwin\bin in Windows Explorer
Right click dash.exe and click "Run as Administrator". A command Prompt should appear with nothing but a $
Type /usr/bin/rebaseall -v, hit enter, and wait for the process to complete.
If you get errors about Cygwin processes running, try Step 1 again. If that still doesn't work, Restart your computer into safe mode and try these steps again.
A commenter noted that, depending on your settings, you may have to type cd /usr/bin && ./rebaseall -v instead.
Try opening Cygwin again.
This process worked for me. I hope it works for you guys too.

I would like to add the following to the above answers, as it is what I had to do after reinstalling Cygwin:
Navigate to the "/usr/bin" directory (usually, C:\cygwin\bin) and right click, Run as Administrator the file: dash.exe
Then, at the $ prompt type the following, hitting enter after each line:
cd /usr/bin/
/usr/bin/peflags * -d 1
/usr/bin/rebaseall -v
What it does is, it marks the dll's as "rebase-able," and then rebases them. You have to have peflags.exe in addition to the above files (in previous answers). You may have to restart windows after doing this and you will definitely need to make sure that there are no processes nor services belonging to cygwin running. (Use task manager, kill any related processes, and then under the services tab look for any service starting with CYG and stop it.)
After doing this, I was able to get cygwin to run without any errors about dll's being loaded to the wrong addresses aka fork errors, etc.
I hope that this helps others, as it was a pain to find.
SOURCE: http://www.cygwin.com/faq.html#faq.using.fixing-fork-failures
and the rebase README file.
To add on to other answers here, we ran into the same issue but could not run the rebase command from the ash or dash shell. However, when launching the command from the Windows cmd shell, the following worked.
cmd /c "C:\cygwin64\bin\ash.exe /usr/rebaseall -v"
-v is to get verbose output
I found another information here :
http://cygwin.com/ml/cygwin/2014-02/msg00531.html
You have to delete the database at
/etc/rebase.db* and do in a "ash" windows :
peflags * -d 1
rebaseall
It works for me on 2 servers.
I solved this problem by restarting my computer. Probably installed a driver update and kept using sleep instead of shutting down.
Experienced the same issue when loading Cygwin with cygiconv-2.dll forking and not loading successfully in the Cygwin terminal, but after turning off my AntiVirus (it was specifically Ad-aware), the issue resolved, and Cygwin worked properly.
In case you are using babun's Cygwin, after rebaseall, try launching Cygwin by executing .babun\cygwin\cygwin.bat in a Windows command prompt or Windows explorer.
This works for me (while launching babun's default console - mintty results in fork error).
I had the error on win10 and i was trying to rebase to c: before install.
then i saw that the installer was installing it instead to c:/Users/myuser
so i was coping all files from c:/Users/myuser to c:.badun
and then restart plus open badun.bat
not shure if this was wise its now duplicated XD... but then it worked again.
Rebaseing didn't help in my case. In addition to what other people suggested, I noticed that reducing the length of PATH environment variable fixed the issue for me (and for other people as well as can be seen from this answer).
This issue is intermittent in nature & I found this issue when there is network is too slow to connect to remote machine on AWS.... I have Shell script that runs through Gitbash shell & it connects to AWS EC2 instance with ssh..... Most of the time, it ran correctly but 2 out 100 times it get into this issue bash: fork: retry: Resource temporarily unavailable .... Killing the MSYS2 terminal from task manager helps to overcome with this issue....
Negative side is you need to run the scripts from the beginning...
I had the same issue on Windows 10 and the mobaxterm app (which uses cygwin) and I tried all of answers listed here however for me, the solution was to simply delete the "CryptoPro CSP" application.
I started facing this problem after upgrading to windows 10. As of now I do not see that any of the above method working.
What I am noticing is that if you start cygwin with admin right (right click and say "run as admin") then it works fine.
Or you open cmd as administrator and then launch cygwin from there, then also it runs fine.
Just reinstall cygwin and select TCL and activate EXPECT
I'm followint these instructions to install Kile+TexLive 2010 with package manager on my Ubuntu Maverick: http://ubuntuforums.org/showthread.php?t=141934
The problem I have is that when I finish downloading all the packages to my computer, I have to edit the path but Ubuntu doesn't recognize it. The lines are the following:
PATH=/usr/local/texlive/2005/bin/i386-linux:$PATH
export PATH
I run echo $PATH and as long as I don't close the terminal, the path appears with the echoing, but if I close it, the path disappears. Nevertheless (whether I close the terminal or not), I'm supposed to run texhash but I am told that the command is not found. I already tried editing the path by adding the two lines above to both .bashrc in my home directory and to bash.bashrc in /etc/ directory.
I'm just following the instructions linked above, but I'm a linux rookie. Could anyone help, please?
in order to permanently change any environment variable under Ubuntu/Linux, you must modify the files you mentioned (for example ~/.profile). If you simply issue an export via the terminal, its effect will end once the terminal is closed. Sometime it is needed to perform a logout/login for the changes to take effect.
Also, mind the syntax of what you write in the above mentioned file(s), like "'s around $PATH.
