• Ubuntu安装PyCharm


    1. 下载

    http://www.jetbrains.com/pycharm/download/

    选择Linux Tab,选择下载免费的Community Edition【1】。当前版本是3.4

     

    2. 安装PyCharm

    按照官网给出的安装指导【2】进行安装。

    (1) Copy the pycharm-*.tar.gz to the desired installation location (make sure you have rw permissions for that directory)

    $ cd Downloads/

    (2)Unpack the pycharm-*.tar.gz using the following command: tar xfz pycharm-*.tar.gz

    $ tar xfz pycharm-*.tar.gz

    (3)Remove the pycharm-*.tar.gz to save disk space (optional)

    $ rm  pycharm-*.tar.gz

    (4)Run pycharm.sh from the bin subdirectory

    $ cd pycharm-community-3.4.1/bin/

    $ ./pycharm.sh

    但是安装开始,出现如下错误:

    ERROR: Cannot start PyCharm

    No JDK found. Please validate either PYCHARM_JDK, JDK_HOME or JAVA_HOME environment variable points to valid JDK installation.

    打开pycharm.ch文件查看,发现报错的地方在:

    复制代码
    message()
    {
      TITLE
    ="Cannot start PyCharm"
      if [ -t 1 ]; then
        echo "ERROR: $TITLE

      elif [ -n `which zenity` ]; then
        zenity --error --title="$TITLE" --text="$1"
      elif [ -n `which kdialog` ]; then
        kdialog --error --title "$TITLE" "$1"
      elif [ -n `which xmessage` ]; then
        xmessage -center "ERROR: $TITLE: $1"
      elif [ -n `which notify-send` ]; then
        notify-send "ERROR: $TITLE: $1"
      else
        
    echo "ERROR: $TITLE $1"
      fi
    }

      JDK="$JDK_HOME"
    elif [ -n "$JAVA_HOME" -a -x "$JAVA_HOME/bin/java" ]; then
      JDK="$JAVA_HOME"
    else
      JAVA_BIN_PATH=`which java`
      if [ -n "$JAVA_BIN_PATH" ]; then
        if [ "$OS_TYPE" = "FreeBSD" -o "$OS_TYPE" = "MidnightBSD" ]; then
          JAVA_LOCATION=`JAVAVM_DRYRUN=yes java | "$GREP" '^JAVA_HOME' | "$CUT" -c11-`
          if [ -x "$JAVA_LOCATION/bin/java" ]; then
            JDK="$JAVA_LOCATION"
          fi
        elif [ "$OS_TYPE" = "SunOS" ]; then
          JAVA_LOCATION="/usr/jdk/latest"
          if [ -x "$JAVA_LOCATION/bin/java" ]; then
            JDK="$JAVA_LOCATION"

        elif [ "$OS_TYPE" = "Darwin" ]; then
          JAVA_LOCATION=`/usr/libexec/java_home`
          if [ -x "$JAVA_LOCATION/bin/java" ]; then
            JDK="$JAVA_LOCATION"
          fi
        fi
    
        if [ -z "$JDK" -a -x "$READLINK" -a -x "$XARGS" -a -x "$DIRNAME" ]; then
          JAVA_LOCATION=`"$READLINK" -f "$JAVA_BIN_PATH"`
          case "$JAVA_LOCATION" in
            */jre/bin/java)
              JAVA_LOCATION=`echo "$JAVA_LOCATION" | "$XARGS" "$DIRNAME" | "$XARGS" "$DIRNAME" | "$XARGS" "$DIRNAME"`
              if [ ! -d "$JAVA_LOCATION/bin" ]; then
                JAVA_LOCATION="$JAVA_LOCATION/jre"
              fi
              ;;
            *)
              JAVA_LOCATION=`echo "$JAVA_LOCATION" | "$XARGS" "$DIRNAME" | "$XARGS" "$DIRNAME"`
              ;;
          esac
          if [ -x "$JAVA_LOCATION/bin/java" ]; then
            JDK="$JAVA_LOCATION"
          fi
        fi
      fi
    fi
    
    if [ 
    -z "$JDK"
     ]; then
      message 
    "No JDK found. Please validate either PYCHARM_JDK, JDK_HOME or JAVA_HOME environment variable points to valid JDK installation."
      exit 1
    fi
    复制代码

    说明没有找到JDK location path。需要安装并配置JDK了。

     

    3. 安装JDK

    首先查了一下Ubuntu12.04是否支持JDK8,发现还是支持的。那就放心安装吧。

    参照【3】的方法,通过设置源仓库的方式安装。(如果想手动安装,请参考【5】【6】)

    Important: This PPA supports Ubuntu 14.04, 13.10, 12.04 and 10.04 as well as the corresponding Linux Mint versions. Ubuntu 13.04 and 12.10 are no longer supported by Canonical

    (1)返回到Home目录:“~”,然后依次执行一下几条command

    sudo add-apt-repository ppa:webupd8team/java
    sudo apt-get update
    sudo apt-get install oracle-java8-installer

    安装过程中会跳出Oracle license对话框,选择接受就是了。

    (2)安装完成后,运行"java -version"或者"javac -version"查看是否安装成功。如果得到类似如下的输出,表明安装成功了。

    $ java -version
    java version "1.8.0_20"
    Java(TM) SE Runtime Environment (build 1.8.0_20-b26)
    Java HotSpot(TM) 64-Bit Server VM (build 25.20-b23, mixed mode)
    $ javac -version
    javac 1.8.0_20

    (3) 在【3】中说道,如果想automatically set up the Java 8 environment variables,可以使用下面的command:

    http://www.webupd8.org/2012/01/install-oracle-java-jdk-7-in-ubuntu-via.html
    http://www.webupd8.org/2012/09/install-oracle-java-8-in-ubuntu-via-ppa.html

    sudo apt-get install oracle-java8-set-default

    我使用该command后,在Terminal中运行 echo $JAVA_HOME,没有任何输出。看来是没起什么作用。有可能是在一开始配置完repository后,安装时使用该条命令,可以以后尝试一下。

    UPDATED: 使用 sudo apt-get install oracle-java8-set-default,测试echo $JAVA_HOME,仍然是没有$JAVA_HOME环境变量的。还是需要手动设置。

    由于一些程序在运行时可能默认需要 $JAVA_HOME 环境变量,因此还是需要设置一下环境变量的。

     

    4. 配置$JAVA_HOME 环境变量

    参考【4】中 Setting the "JAVA_HOME" environment variable 一节进行设置。

    (1)Find out the path of your Java installation:

    sudo update-alternatives --config java

    它将返回类似如下的结果,列出了本机所安装的所有Java运行时环境JRE。(共有2个:JDK7和OpenJDK6,0和2是同一个,auto mode和manual mode的差别)

    复制代码
    There are 2 choices for the alternative java (providing /usr/bin/java).
    
    Selection    Path                                            Priority   Status
    ------------------------------------------------------------
    * 0            /usr/lib/jvm/java-7-oracle/jre/bin/java          1062      auto mode
      1            /usr/lib/jvm/java-6-openjdk-amd64/jre/bin/java   1061      manual mode
      2            /usr/lib/jvm/java-7-oracle/jre/bin/java          1062      manual mode
    
    Press enter to keep the current choice[*], or type selection number:
    复制代码

    对应的各个JRE的 安装路径分别为:

    0. /usr/lib/jvm/java-7-oracle

    1. /usr/lib/jvm/java-6-openjdk-amd64

    2. /usr/lib/jvm/java-7-oracle

    在我本机 执行 sudo update-alternatives --config java 的结果为:

    Selection    Path                                     Priority   Status
    ------------------------------------------------------------
      0            /usr/lib/jvm/java-8-oracle/jre/bin/java   1         auto mode
    * 1            /usr/lib/jvm/java-8-oracle/jre/bin/java   1         manual mode
    
    Press enter to keep the current choice[*], or type selection number:

    可见只安装了一个Java环境: JDK8。它对应的安装路径为:

    /usr/lib/jvm/java-8-oracle

    (2)编辑/etc/environment文件

    sudo nano /etc/environment

    复制上面的路径 /usr/lib/jvm/java-8-oracle,添加如下一行

    JAVA_HOME="/usr/lib/jvm/java-8-oracle"

    (3) Reload该文件,使之立即生效,而不必注销并重新登录

    source /etc/environment

    (4)使用下面的命令测试

    echo $JAVA_HOME

    会输出刚才所设置的路径 /usr/lib/jvm/java-8-oracle。

    5. 再次安装PyCharm

    (1)cd到Downloads/pycharm-community-3.4.1/bin/目录,执行./pycharm.sh。询问是否导入settings,选择不导入->OK.

    image

    (2) 初始设置,保持默认->OK.

    575D0ZC`9]VL5A8A@C)%)U8

    (3) 创建一个Launcher脚本,需要输入密码。

    image

    用户名
    yueting3527

    FFR8k"nGzJHzjQT6IBG!1fbQZn9!Vi
    ===== LICENSE END =====

    (4)出现下面的画面,表明安装成功了。

    ]0RBN}ANEVT{8(BEG]Z{P0I

    (5) Create New Project,创建一个测试工程,解释器默认选择了Python2.7。

    `H2I[1FUMP~A`J}UQ``]%GG

    然后在新创建的工程上:点右键->New->Python File, 创建一个新的文件Py01,写代码,点Run按钮->Run Py01运行。

     

    6. 设置Ubuntu下Pycharm的快捷启动方式

    在Ubuntu下,每次都要找到 pycharm.sh所在的文件夹,执行./pycharm.sh,非常麻烦。最好能创建一个快捷方式。【7】

    Ubuntu的快捷方式都放在/usr/share/applications,首先在该目录下创建一个Pycharm.desktop

    $ sudo gedit /usr/share/applications/Pycharm.desktop

    然后输入以下内容,注意Exec和Icon需要找到正确的路径

    复制代码
    [Desktop Entry]
    Type=Application
    Name=Pycharm
    GenericName=Pycharm3
    Comment=Pycharm3:The Python IDE
    Exec="/XXX/pycharm-community-3.4.1/bin/pycharm.sh" %f
    Icon=/XXX/pycharm-community-3.4.1/bin/pycharm.png
    Terminal=pycharm
    Categories=Pycharm;
    复制代码

    然后双击打开,再锁定到启动器就好了.
