Installation of Pycharm

For some reason, to install pycharm on a very old XP computer, but because the system version is too low, there are a lot of problems in the installation process, here to make a simple record of these problems;

First, the installation of Python

Download path for 1.Python: https://www.python.org/downloads/windows/

Note: The last version of Python support for XP is 3.4.4 : Https://www.python.org/ftp/python/3.4.4/python-3.4.4.msi

Settings for 2.python environment variables

Find the path of the system environment variable, add C:\Python34; C:\Python34\Scripts;

3. Check if Python installation is complete

Enter CMD in the run, go to the command line, enter Python--version, see if the Python version is returned, and if the version information is returned normally, the installation is complete;

Second, the installation of Pycharm

Download path for 1.pycharm: http://www.jetbrains.com/pycharm/download/#section =windows

2. After the download is complete, follow the steps to install, after the installation is complete, the first time to open the pycharm, there may be several error messages:

1) Could not find main class Com/intellij/idea/main

Cause: This old XP computer was installed before the JDK version is 1.6.0, the version is too low, resulting in the inability to run pycharm;

Workaround: Re-download the 1.8.0 version of the JDK, but found that on the XP computer can not run the installation of the JDK exe download files, and later through the 7-zip decompression tool to extract the JDK file can be used normally, the specific steps see https:// jingyan.baidu.com/article/ae97a646aa47aebbfd461df1.html;

2) Theenvrionment variable java_home does not point to a valid JVM installatio

Cause: found that the relevant environment variables are not well-equipped;

Workaround: Verify that the information for the following three environment variables is configured correctly

• Java_home Value: D:\Program files\java\jdk1.8.0 (Install JDK directory, note that this environment variable does not add ";" after the path, and found that there are cases where adding ";" will cause Pycharm to run the Times wrong)
• Value of classpath:.; %java_home%\lib\tools.jar;%java_home%\lib\dt.jar;%java_home%\bin; (Note the preceding ".;" To add, if not new)
• Value of path: Append at start.; %java_home%\bin;%java_home%\jre\bin; (Note the preceding ".;" To add, if not new)
