Numpy of
pycharm suddenly became unavailable. At first, I thought numpy version was a problem. Uninstall, reinstall, upgrade, and degrade were not allowed.
then I tested the numpy of anaconda and found that it could be used, but pycharm could not. However, I checked the setting repeatedly, and there was no problem.
finally put solution : system environment variable Path to the bin level C:\ProgramData\Anaconda3\Library\bin, and then restart the computer.
at first I just introduced Anaconda3, but before using numpy I had no problem, maybe I updated conda, the package is confused, so the environment variable introduced must be bin level.
recently had this problem while working on the Jenkins build release,

if you have experienced a similar error, try my method and see if you can solve it. The error case diagram is as follows:
when installing ubuntu with livecd, ubi-partman failed with code 141 May occur when the hard disk partition step is taken. The solution:
Ctrl+Alt+t pop-up terminal, input:
sudo fdisk /dev/sda
#sda is my hard disk device number, according to your system, it should be modified to the appropriate device number
then take a look at the partitions above sda with the p command, delete all Linux native and swap partitions with the d command (NTFS \ fat32 are for Windows, needless to say you wouldn’t dare to touch them), then write to the partition table with the w command, then double-click Install Ubuntu icon again, enter the installation process, everything is ok.
environment:
unity2018.4.1
jdk1.8.0 _221
is actually a normal procedure and there’s nothing wrong with it.
and then I found that your package today at a wrong CommandInvokationFailure: Gradle build failed. Just this one down here.
I didn’t know how to do it for a while, I thought it was my SDK that was not configured or the JDK version was wrong, but I felt there was no problem. I checked baidu online and found that many people had made this mistake, but they all put forward the problem and there was no good solution.
is generally said to Build System to choose Internal, but this does not seem to work well when it comes to signing certificates, just skipping this issue.
is also a problem with the NDK, the tools aren’t right, gradle isn’t installed, the name of AndroidMainfest, or the JDK version or android SDK. There’s a lot to say.
. signature certificate ?
so go to create a secret key
packaging again, oh huo, success!
in case something weird happens, it’s better not to have Chinese paths.

reason:
1, SQL*Loader user has no permission to create files;
2, because the target path does not exist, SQL*Loader reported this error (not verified)
When you are using
sudo apt-get update
fail and show
Some index files failed to download. They have been ignored, or old ones used instead
You can try
sudo su
vim /etc/resolv.conf
add
nameserver 8.8.8.8
and retry
sudo apt-get update
It will work
good luck!
Aptana Studio3 installation problem
reprinted
before has been using Dreamweaver to write HTML, after browsing the forum found that many people use Aptana Studio, then to download the official website, in the installation process appeared a lot of problems.
Click on aptana’s installer, and wait about 10 minutes for a dialog to pop up
“12029 http://go.appcelerator.com/installer_nodejs_windows.msi.” , according to the determined, according to the aptana no successful installation, click finish to exit the, and baidu aptana installation tutorial. Aptana needs to run Node. js and Git. For these two development environments, I have downloaded and installed the 64-bit Node. js and Git from the official website.
Click the installer for Aptana again, and the prompt box appears
” node.js mandatory installed was not installed correctly.”.Js has not been installed correctly.
Reinstall Aptana, and the prompt box appears again
Msi: CRC error.” is still the problem of node.js, which is supposed to need 32-bit node.js, so uninstall the original, download and install the 32-bit node.js from the official website.
After installing Aptana again, I still have the same problem. So I go to the Internet and look for the version of Node. js on Stackoverflow, I see a god saying it’s the wrong version of Node. js, download and install the node.js he provided.
node-v0.10.13-x86), reinstall aptana in less than 5 minutes!!

likely you are trying to import a failed build of numpy.
If you're working with a numpy git repo, try `git clean -xdf` (removes all
