The following error occurred when compiling Android:
[ 28% 1127/3932] Ensuring Jack server is installed and started
FAILED: setup-jack-server
Picture:
Reason: when Jack compiles, there may be multiple people compiling at the same time. At this time, there may be two people using the same port, resulting in port conflict and timeout.
Solution: modify the port number (modify the. Jack settings and. Jack server/config. Properties files)
Step 1:
Open the. Jack settings file in the root directory of the project, and modify Jack. Server. Service. Port and Jack.server.admin.port port. Set the port number as large as possible to reduce the probability of port collision. For example, I set jack.server.service.port to 28078 and jack.server.admin.port to 28079
# Server settings
SERVER_HOST=localhost
SERVER_PORT_SERVICE=28078
SERVER_PORT_ADMIN=28079
# Internal, do not touch
SETTING_VERSION=4
Step 2:
Open the. Jack-server/config.properties file in the root directory of the project, and set jack.server.service.port and jack.server.admin.port to the same values as the steps.
jack.server.idle=180
jack.server.max-service.by-mem=1\=2147483648\:2\=3221225472\:3\=4294967296
jack.server.shutdown=21600
jack.server.time-out=7200
jack.server.max-jars-size=104857600
jack.server.service.port=28078
jack.server.admin.port=28079
jack.server.config.version=4
jack.server.max-service=4
jack.server.deep-idle=900After modification, if there is no conflict, you can compile normally.
Error in installing pyqt5 on Ubuntu 18.04:
command “Python setup.py egg”_ info” failed with error code 1 in /tmp/pip-build-92ggdywh/PyQt5/
As a result, the version of PIP is too low. The default system version is pip9, so we need to update the PIP version
the update method is as follows:
python3 -m pip install --upgrade pip
Because most of the time, we install python, or apt install Python directly, resulting in the installation of python2.7. If you just want to use a version of python, such as python3, you can uninstall python2. It’s better to uninstall to avoid conflicts.
Using the sudo Yum install docker CE docker CE cli containerd.io command to install docker, an error is reported, and the log is as follows:
I am using alicloud’s image source.
Solution:
modify the configuration file/etc/yum.conf and add sslverify = 0.
Some people on the Internet recommend changing the content of the. Condar file, but I failed
Some people may recommend re installing anaconda, but that would be too cumbersome
CONDA update CONDA the problem can be solved immediately by updating the CONDA version
When git runs clone or push command, an error is reported. Could not resolve host: github.com:
First Ping github.com, and then I’ll go straight to the following figure:
According to the obtained IP is 13.250.177.233.
Edit system file hosts
It’s running again Git clone URL succeeded!
1、 Background
Due to the need of work, I installed and deployed a Jenkins, and configured a job for a project. Among them, you need to SSH from Jenkins machine to other remote machines to solve the problem of wrong report!!!
Permission denied (publickey,gssapi-keyex,gssapi-with-mic,password)
2、 Solutions
Baidu online meal, basically are wrong answers. In fact, it is because there is no configuration of password free login, so let the operation and maintenance colleagues help to do the password free login between servers, the result is still not good!!! Finally, after the guidance of my colleagues, I found that my Jenkins was started with jboss5, so my password free permission should also be jboss5 permission, but the actual operation and maintenance colleagues helped to do root permission, so the above error was not solved.
Reconfiguring jboss5’s password free login is OK
configure: error: Package requirements (sqlite3 > 3.7.4) were not met:
Reason: the above error occurred when configuring php-7.4.19 in centos8 environment because of the lack of SQLite related libraries
The solution is as follows
Yum - y install SQLite devel
