Java, Caused by: java.io.IOException: error=2, No such file or directory
command, java
Solution
I finally found the answer, because the Process I start is different with the process of the terminal, so can't access /usr/local/bin, have to add `-l` to run the command as logged in user. `Runtime.getRuntime().exec(new String[]{"bash", "-l", "-c", cmd}, null, new File(f))`
Problem
``` java.io.IOException: Cannot run program "yarn": error=2, No such file or directory at java.lang.ProcessBuilder.start(ProcessBuilder.java:1048) at java.lang.Runtime.exec(Runtime.java:620) at java.lang.Runtime.exec(Runtime.java:450) at java.lang.Runtime.exec(Runtime.java:347) at com.Main.main(Main.java:32) ``` Hi there, I have a weird problem when execute a command using Java. I used the following code to run a command, if I run `mkdir testFolder`, the program run successful, but if I changed the command like `yarn -v` then error happen. ``` try { Process process = Runtime.getRuntime().exec("yarn -v");//, null, new File("/Users/macos/Desktop/TestProj/")); } catch (IOException ex) { ex.printStackTrace(); } ``` P/s: In debug mode: IntelliJ could run above code, but Netbeans failed. In production mode (jar file): IntelliJ failed too. Edit 2: ``` MACs-MacBook-Pro:~ macos$ which pwd /bin/pwd MACs-MacBook-Pro:~ macos$ which mkdir /bin/mkdir MACs-MacBook-Pro:~ macos$ which java /usr/bin/java MACs-MacBook-Pro:~ macos$ which yarn /usr/local/bin/yarn ``` I found that if I run a command that is in `/bin` or `/usr/bin`, the code run ok (pwd, mkdir, java -version ...), but yarn is in `/usr/local/bin/`, so it didn't work, and I still don't know how to fix.
