Question

Ubuntu 18.04，Python 2.7

我尝试

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'

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

/ tmp / pip-install-voWMrv / javabridge /

中的命令“ python setup.py egg_info”失败，错误代码为1

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。

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

Answer 1

您似乎遇到了this issue。 javabridge软件包未更新为Java 9/10/11中有关JRE目标目录（以除去目标拱门而命名的中间目录）的重组的更改，因此您目前只能使用Java 8。这是我可以在javabridge Docker容器中成功安装ubuntu:latest的方式：

$ 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，删除后缀jre/bin/java以获取JDK根。

现在安装javabridge：

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

https://pythonhosted.org/javabridge/installation.html#dependencies：

Javabridge需要Python 2.6或更高版本，NumPy，Java开发工具包（JDK）和C编译器。

sudo apt install python2.7 python-numpy openjdk-8-jdk gcc

无法点安装javabridge
