无法点安装javabridge [英] Can't pip install javabridge

问题描述

Ubuntu 18.04，Python 2.7

Ubuntu 18.04, python 2.7

我尝试

sudo pip install javabridge

我知道

      Complete output from command python setup.py egg_info:
Traceback (most recent call last):
  File "<string>", line 1, in <module>
  File "/tmp/pip-install-voWMrv/javabridge/setup.py", line 396, in <module>
    ext_modules=ext_modules(),
  File "/tmp/pip-install-voWMrv/javabridge/setup.py", line 131, in ext_modules
    library_dirs = [os.path.dirname(jvm_so)]
  File "/usr/lib/python2.7/posixpath.py", line 122, in dirname
    i = p.rfind('/') + 1
AttributeError: 'NoneType' object has no attribute 'rfind'

----------------------------------------

/tmp/pip-install-voWMrv/javabridge/

Command "python setup.py egg_info" failed with error code 1 in /tmp/pip-install-voWMrv/javabridge/

我能够做到

sudo pip install javabridge==1.0.16

但是事实证明，我需要最新的版本1.0.17，为此我仍然会遇到上述错误.

But it turns out that I need the newest one, 1.0.17, for which I still get the error above.

此命令

find /usr/lib/jvm/java-11-openjdk-amd64 -type f -name "*jvm.so"

给予

/usr/lib/jvm/java-11-openjdk-amd64/lib/server/libjvm.so

然后我跑了

JAVA_HOME=/usr/lib/jvm/java-11-openjdk-amd64
~$ JDK_HOME=/usr/lib/jvm/java-11-openjdk-amd64

最后

sudo pip install javabridge --user myName

给出相同的错误

Complete output from command python setup.py egg_info:
    Traceback (most recent call last):
      File "<string>", line 1, in <module>
      File "/tmp/pip-install-i61jKx/javabridge/setup.py", line 396, in <module>
        ext_modules=ext_modules(),
      File "/tmp/pip-install-i61jKx/javabridge/setup.py", line 131, in ext_modules
        library_dirs = [os.path.dirname(jvm_so)]
      File "/usr/lib/python2.7/posixpath.py", line 122, in dirname
        i = p.rfind('/') + 1
    AttributeError: 'NoneType' object has no attribute 'rfind'

我也尝试过

JAVA_HOME=/usr/lib/jvm/java-11-openjdk-amd64 JDK_HOME=/usr/lib/jvm/java-11-openjdk-amd64 pip install javabridge --user

推荐答案

您似乎遇到了

It looks like you're running into this issue. javabridge package is not updated to changes in Java 9/10/11 regarding the restructuring of the JRE target dir (an intermediate dir named after the target arch removed), so you can only use the Java 8 at the moment. This is how I could install javabridge successfully in an ubuntu:latest docker container:

$ apt update
$ apt install software-properties-common
$ add-apt-repository ppa:webupd8team/java
$ apt install openjdk-8-jdk
$ update-alternatives --config java

这应该为您提供类似于/usr/lib/jvm/java-8-openjdk-amd64/jre/bin/java的OpenJDK 8路径，删除jre/bin/java后缀以获取JDK根.

This should give you the path to OpenJDK 8 similar to /usr/lib/jvm/java-8-openjdk-amd64/jre/bin/java, remove the jre/bin/java suffix to get the JDK root.

现在安装javabridge:

$ JAVA_HOME=/usr/lib/jvm/java-8-openjdk-amd64 pip install javabridge --user
