尝试运行pycharm-community-4.5时出现Java问题

我刚刚将pycharm-community-4.5安装到我的Ubuntu 14.04（64位）中。 安装完成后，我运行了命令/opt/pycharm-community-4.5/bin$ ./pycharm.sh来运行pycharm，但终端显示了一些错误，如下 –

 Unrecognized VM option MaxPermSize=350m Error: Could not create the Java Virtual Machine. Error: A fatal exception has occurred. Program will exit. 

这是我的java -version的结果：

 java version "1.8.0_45" Java(TM) SE Runtime Environment (build 1.8.0_45-b14) Java HotSpot(TM) 64-Bit Server VM (build 25.45-b02, mixed mode) 

我如何解决它？

Answer 1

打开文件pycharm64.vmoptions

 nano /opt/pycharm-community-4.5/bin/pycharm64.vmoptions 

并在行的开头添加#

 # -XX:MaxPermSize=350m 

打开文件pycharm.vmoptions

 nano /opt/pycharm-community-4.5/bin/pycharm.vmoptions 

并在行的开头添加#

 # -XX:MaxPermSize=250m 

---

Java 8.0中删除了MaxPermSize支持，但错误消息

 Unrecognized VM option MaxPermSize=350m Error: Could not create the Java Virtual Machine. Error: A fatal exception has occurred. Program will exit. 

看起来不像Oracle Java 8或OpenJDK 8。

PyCharm启动程序pycharm.sh尝试查找Java：

 # --------------------------------------------------------------------- # Locate a JDK installation directory which will be used to run the IDE. # Try (in order): PYCHARM_JDK, ../jre, JDK_HOME, JAVA_HOME, "java" in PATH. # --------------------------------------------------------------------- if [ -n "$PYCHARM_JDK" -a -x "$PYCHARM_JDK/bin/java" ]; then JDK="$PYCHARM_JDK" elif [ -x "$IDE_HOME/jre/bin/java" ] && "$IDE_HOME/jre/bin/java" -version > /dev/null 2>&1 ; then JDK="$IDE_HOME/jre" elif [ -n "$JDK_HOME" -a -x "$JDK_HOME/bin/java" ]; then 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" fi 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 

1. $PYCHARM_JDK
2. $IDE_HOME/jre/bin/java
3. $JDK_HOME
4. $JAVA_HOME

确保您使用的是您想要使用的Java版本。

Answer 2

查看您提取的pycharm文件夹的bin文件夹。

有一些名为pycharm64.vmoptions和pycharm.vmoptions文件。 在它们内部，您可以使用MaxPermSize=350m的罪魁祸首选项删除该行。
