java - 无法通过 pip 安装 javabridge

Question

Ubuntu 18.04， python 2.7

我试试

sudo pip install javabridge

我明白了

      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'

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

命令“python setup.py egg_info”在/tmp/pip-install-voWMrv/javabridge/中失败，错误代码为 1

我能做到

sudo pip install javabridge==1.0.16

但事实证明我需要最新的，1.0.17，为此我仍然得到上面的错误。

这个命令

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

同样的错误

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'

我也试过

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

看起来您遇到了 this issue . javabridge 包未更新到 Java 9/10/11 中关于重组 JRE 目标目录(以删除的目标 arch 命名的中间目录)的更改，因此您只能使用 Java 8此时此刻。这就是我如何在 ubuntu:latest docker 容器中成功安装 javabridge:

$ 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 后缀获取 JDK 根。

现在安装javabridge:

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