I have opened ticket 239, 8.2.0 cannot run pythons and pips, "java.io.IOException: Cannot run program".
#18g9323 update
I speculate that a proper fix requires an update to LiClipse. The combination of these differences seems to let the Java VM environment succeed in calling the host's native environment. The change to LiClipse.ini means that LiClipse uses a different OpenJDK, and invokes libjli differently. I speculate that LiClipse was trying to call macOS to run the Python interpreter, but this attempt failed because the Java VM environment could not call the host's native environment successfully. Java.io.IOException: Cannot run program "/opt/local/Library/Frameworks/amework/Versions/3.7/Resources/Python.app/Contents/MacOS/Python": error=316, posix_spawn failed The libjli.so contains a launcher interface for preparing arguments passed in the command line and launching the virtual machine with them.… It looks like it helps interaction between the Java VM environment and the hosts's native language environment.
#18g9323 windows
There are clues in a StackOverflow answer, What is the Java libjli library for?, and in a blog post, Calling Java From C. 6 (18G9323)) or set it to standby with an open SSH Remote Development session, all P圜harm windows are frozen, no buttons work anymore. I don't know enough about the JDK to know what library libjli.dylib does. The inserted lines look to me like they tell the launcher to specify a different Java VM to use when running the main Eclipse/LiClipse application - to use the OpenJDK 18.0.1 supplied by Eclipse, saved in ~/.p2/, instead of the OpenJDK 14.0.2 supplied by LiClipse and also to invoke a library libjli.dylib. macOS runs a launcher program, and the launcher is guided by the contents of the ini file.
The LiClipse.ini file controls how the app starts up. OpenJDK 64-Bit Server VM AdoptOpenJDK (build 14.0.2+12, mixed mode, sharing) on a system running macOS Mojave 10.14.6 (18G9323) The Canon Office Printer Utility detects that the printer has a Duplex unit (screenshot attached). OpenJDK Runtime Environment AdoptOpenJDK (build 14.0.2+12) Evidence of difference: % /Applications/LiClipse.app/jre/Contents/Home/bin/java -version What I think is happening is that Eclipse supplies an OpenJDK for the app to run, it is different than the OpenJDK supplied by LiClipse, and it supports recent version of macOS better. I am not an expert on the internals of either LiClipse or Eclipse. (This should leave behind /Users//.p2/ undisturbed.) It should now be able to add new interpreter entries in PyDev, with no errors.ĭelete the Eclipse.app. To read (of course replacing with your home directory name, and no line break in the very long line starting "/Users/"…): faultAction Change the lines in that file which read: faultAction Using a plain text editor, edit the file within LiClipse.app, LiClipse.app/Contents/Eclipse/LiClipse.ini.
#18g9323 install
Install a standard Eclipse app of the same vintage (Eclipse 2021-12, version 4.22, corresponds to LiClipse 8.2.0). I don't fully understand why it works, but I have some clues. What I wanted to know: how can I resolve this problem, so that LiClipse can add new interpreter entries in PyDev, and not display errors?
#18g9323 code
The symptoms were similar, except that LiClipse returned error code 316 instead of 0. I had a problem very much like this, except with LiClipse version 8.2.0, running on macOS 12.4 Monterey, with Python interpreters installed by MacPorts. Python works OK via terminal and things like Sublime Text. Looks like it is trying to find it in most obvious locations, but unable to spawn the process to run it? : java.io.IOException: Cannot run program "/usr/local/bin/python3.9": error=0, posix_spawn failed : java.io.IOException: Cannot run program "/usr/local/bin/python3": error=0, posix_spawn failed : java.io.IOException: Cannot run program "/usr/bin/python2.7": error=0, posix_spawn failed : java.io.IOException: Cannot run program "/usr/bin/python": error=0, posix_spawn failed LiClipse just cannot find it! tried all these buttons there (PATH, pip, what not) still the same error: Errors getting info on discovered interpreter(s). * 3.9.7 (set by /Users/aanisimov/.pyenv/version) Homebrew freshly updated (even though also complains OS is too old) and some packages reinstalled to make sure it's all cleared.
#18g9323 mac os
Fairly old Mac OS which might cause this, but mostly everything works OK:
