kandi X-RAY | leveldown Summary

leveldown is a C++ library typically used in Server, Runtime Evironment, Nodejs applications. leveldown has no bugs, it has no vulnerabilities, it has a Permissive License and it has low support. You can download it from GitHub.

This module was originally part of levelup but was later extracted and now serves as a stand-alone binding for LevelDB. It is strongly recommended that you use levelup in preference to leveldown unless you have measurable performance reasons to do so. levelup is optimised for usability and safety. Although we are working to improve the safety of the leveldown interface it is still easy to crash your Node process if you don't do things in just the right way. See the section on safety below for details of known unsafe operations with leveldown.

Here are some references that might help:

Try installing Truffle via PowerShell in Admin mode (very important that you're in Admin mode)

You'll need to allow scripts to run as an Admin in PowerShell. To do this, here are some references in the threads in Stack Overflow:

I ran the command Set-ExecutionPolicy -Scope CurrentUser -ExecutionPolicy Bypass -Force in PowerShell to get this to work, but please reference the threads above before doing this.

You have to install Visual Studio Community 2022 as well as Visual Studio Code. And when installing Visual Studio Community, you have to install desktop development with C++ with some optional packages.

electron-builder fails building linux package on macos - Error: Unknown target: build

Asked 2020-Nov-20 at 12:51

I'm using electron-builder to package my application. I have a dist/ folder where all resources are. main.js in root folder does not need any transpiling and includes main process code. This works well in development mode when launching using electron command.

I have electron-builder set up using package.json configuration:

ANSWER

Answered 2020-Nov-20 at 12:51

As per the electron-builder CLI documentation, all platform switches accept a "target list", which in essence is what you configure in your package.json with your different platform entries (build..target, e.g. build.linux.target).

However, by using these target lists, you can specify which targets you want to build and exclude all others. Since Linux' switch is the last in the switch list -ml, Electron Builder interprets this as though you want to pass it a target list. This does not apply to the macOS build step because then you would have to use -m -l , -ml apparently only applies to Linux.

Thus, by appending build to the command line, you tell Electron Builder to compile all configured targets for macOS but only build the Linux target called build. Since there is no such target, Electron Builder crashes. Removing build from your command will do the trick.

QUESTION

Invalid Version TypeError when using nw-gyp to build the leveldown module for Windows PouchDB

Asked 2020-Jul-19 at 03:50

I actually found the answer to this question already, and just want to document my finding.

First of all, this problem is not specific to building the leveldown module for Windows PouchDB. From what I have read online, it is a fairly common problem.

It has to do with the fact that nw-gyp somehow forgot the target version of NW between the nw-gyp configure and nw-gyp build command. When this happens, a TyperError: Invalid Version: undefined would be thrown.

ANSWER

Answered 2020-Jul-19 at 03:50

The solution is actually very simple, all you need to do is to set --target= again when you do nw-gyp build, like this:

ANSWER

Answered 2020-Jan-08 at 23:12

You have installed Python 3 but you are running code that expects Python 2. You can install the python2 package and then you may be able to instruct your npm install process to use /usr/bin/python2 instead of /usr/bin/python.

If that's not possible, you should be able to symlink /usr/bin/python to /usr/bin/python2. By default, CentOS 8 doesn't have a /usr/bin/python (it has only python2 or python3 commands), so this should be harmless.

Note that Python 2 has just reached end of life. Any software that still expects Python 2 at this point may not have seen updates in a while.

Vulnerabilities

No vulnerabilities reported

Install leveldown

leveldown exposes a feature of LevelDB called snapshots. This means that when you do e.g. createReadStream and createWriteStream at the same time, any data modified by the write stream will not affect data emitted from the read stream. In other words, a LevelDB Snapshot captures the latest state at the time the snapshot was created, enabling the snapshot to iterate or read the data without seeing any subsequent writes. Any read not performed on a snapshot will implicitly use the latest state.

Support

We aim to support at least Active LTS and Current Node.js releases, Electron 5.0.0, as well as any future Node.js and Electron releases thanks to N-API. The minimum node version for leveldown is 10.12.0. Conversely, for node >= 12, the minimum leveldown version is 5.0.0.
