Error: Source "#openzeppelin/contracts/token/ERC721/ERC721.sol" not found: File not found. Searched the following locations: "".
Currently, all dependencies from #openzeppelin are showing errors like this. But those dependencies have been installed in my node_modules and I don't know why it can't find the file. Is there a way I can set the location, or should I install the #openzeppelin/contracts globally?
UPDATE：I can see that --base-path should be set for solc, but I am still not sure how to apply such setting to slither.
I found a (might be dirty) way to solve it:
Step 1: Go to the directory where all your dependencies are.
In my case, do cd node_modules
Step 2: Call the same command with the updated relative path.
In my case, from slither contracts/MyContract.sol to slither ../contracts/MyContract.sol
And it just works. After going through the doc, I don't think Slither is providing a way to adjust --base-path as a flag.

I have been using ROS Kinetic for a while, and today when I went to make a new catkin workspace following the ROS tutorials page (http://wiki.ros.org/catkin/Tutorials/create_a_workspace) I get a CMake Error stating that PROJECT_NAME is set to Project, which is invalid. I have never run into this issue with any of my other work spaces I have created.
I do not want to mess with toplevel.cmake out of fear of screwing up my other work spaces.
Any ideas why this is happening?
CMake Error at /opt/ros/kinetic/share/catkin/cmake/catkin_package.cmake:91 (message):
catkin_package() PROJECT_NAME is set to 'Project', which is not a valid
project name. You must call project() before calling catkin_package().
Thank you.
I was able to reproduce the above error you are getting. For that what I did is opened my CMakeLists.txt and commented the second line which defines the package Name, i.e., project(package_name). After that, I tried to build my package via catkin_make, but got below error(see the error inside yellow box):
Then, I tried to build the same package after uncommenting the above line. This time I was able to build my package(test, in my case) successfully, without any error.
CMakeLists.txt file contains project() as well as catkin_package() and the former function should be called before catkin_package() inside the file. So, project(package_name) is either missing from your CMakeLists.txt file or is commented.
If it is missing, then manually add it. If it is there, but commented then uncomment it.
Read more about the correct format of CMakeLists.txt file from here.
ironically, you'll be running : sudo apt-get install ros-<distro_name>-catkin to reinstall catkin because even if u clear your entire workspace the problem will persist due to some symbolic link or something broken in the package which will always result in the same error, upon reinstalling catkin it worked for me, knowing that I had the exact same issue.
Had to come answer this because I think I did the same thing OP did. Here's what happened: There are supposed to be TWO CMakeLists.txt in your project folder. One lives at ProjectName/src and should be read-only and should actually be a link to your /opt/ros/your-ros-distro/share/catkin/cmake/toplevel.cmake folder.
If you do like I did, and I'm assuming like OP did, and edit that file, and then use your superuser to overwrite that file, then you are (1) breaking all of your catkin projects, because ALL of the catkin projects link to this one file, AND you're misconfiguring this project because the CMakeLists.txt file you're supposed to modify actually exists a folder deeper, at ProjectName/src/ProjectName/. THIS is where you're supposed to put the CMakeLists.txt file that names your project, where your package.xml file is supposed to go, etc.
If you use superuser to force-overwrite the read-only CMakeLists.txt file then you're going to have a bad day. Fortunately you can fix that file by fixing the toplevel.cmake folder, which you can do by reinstalling the catkin package: sudo apt-get install --reinstall ros-indigo-catkin
And, to put this in terms of OP's question specifically - the project() needs to get named at the inner file, the ProjectName/src/ProjectName/CMakeLists.txt, because again the root file is read-only and should never be modified.
when i use npm i to install node_moudles,but something was wrong.
It said:
PhantomJS not found on PATH
Download already available at C:\Users\hdu42\AppData\Local\Temp\phantomjs\phantomjs-2.1.1-windows.zip
Checksum did not match
But in fact, in this directory on my computer, this file exists.
I don't understand why should I redownload it.
Anybody know? thanks！！！
Error is because of:
Phantomjs present in your \Local\Temp is not matching the checksum; defined in repository which is referring to PHANTOMJS_CDNURL-> environment variable.
Solution:
Download phantomjs from https://bitbucket.org/ariya/phantomjs/downloads/phantomjs-2.1.1-windows.zip
Extract the zip
Add the path of bin C:\Users\YourUser\phantomjs-2.1.1-windows\phantomjs\bin; in your environment path
Total Linux noob here. I am trying to configure a Pleroma development environment on DO droplet. Installed LEMP, installed SSL, installed PostgreSQL, installed Pleroma, so far so good.
Then I installed Node, NPM, cloned Pleroma-FE (apparently it installs in /user/pleroma-fe folder). I am following the very brief build instructions here:
https://git.pleroma.social/pleroma/pleroma-fe
When I get to the command in those build instructions: npm run build
I am getting error: Error: Cannot find module '/user/build/build.js'
It's because actual path to the build file is /user/pleroma-fe/build/build.js
Apologies if this is a duplicate. I see other questions about this.
Fixing npm path in Windows 8 and 10
and the reply seems to set the PATH. This answer might apply to my situation. But my question is: it is clearly already looking in a well defined path (which is different from all the other questions, which don't seem to have well defined path in the error message). But it is the wrong path. How do I make it look in the correct path?
I tried the npm command and specified the complete path, and every variation. and none worked. So it seems fixing the path won't fix this problem.
Sorry I do not currently know enough Linux to be able to fix this. I tried to tag this with Pleroma but I don't have enough reputation to create a new tag. Any help is much appreciated. Thanks in advance.
I continued to work on this with some help of a Linux admin on Fiverr and the Pleroma developers chat with success, thanks to all.
The solution did not involve changing the path. There were several different things going on. First, I needed to change directory into the development project source folder:
cd pleroma-fe
Once I did that, npm found the build module. Next issue was Node was very old and I needed to get the latest version. I used the instruction here for NodeJS (10):
https://nodejs.org/en/download/package-manager/#debian-and-ubuntu-based-linux-distributions
Next issue was npm was missing some modules. This was fixed with:
npm install
After that the build completed with no errors.
npm run build
After a successful build, you will see a list of files that have changed as a result of the build.
Next issue is that simple changes in HTML text were not live, ie. not reflected in the refreshed web page. This is fixed by copying all the resulting build files to the production folder using rsync. In my case the command was:
rsync -av /user/pleroma-fe/dist/ /home/pleroma/pleroma/priv/static/
Pleroma is a neat Twitter-like user interface to ActivityPub fediverse, it includes a Mastodon UI as well, and thanks to the developers for making it free and open source.
I'm running into the following error at the 'stencil init' step.
The path you specified for your "jspm_packages" folder does not exist
The jspm_packages folder doesn't exist in my stencil directory. Is it supposed to be there? I'm wondering which part of the installation might have gone wrong in order for this folder to be missing
If you are seeing this, you can resolve it by installing jspm just in the directory you are working in. This doesn't help if you need jspm for other projects, but it will get you working for the time being with Stencil.

About a week ago I installed golang successfully on my computer and got it's terminal commands to process. So by that, I know go is on my computer.
I have been looking for a good IDE and found https://code.google.com/p/liteide/ LiteIDE which was made specifically for Go.
I read that if you already had go installed on your computer then you could use LiteIDE to start building your code right away. I must have read something wrong some where because I cannot get my projects to build at all. I think it there may be a missing/incorrect path and or something is just setup incorrectly.
This is the error I get in the console:
Current environment change id "win64-user"

First_Lite_Go_Proj [C:/go/src/First Litel Go Proj]
Error: process failed to start.
I checked the C:/go directory to make everything there is correct and it was. Also I'm using 64bit windows 7 and double checked that as well.
Any ideas? Mine are: Missing/Incorrect Paths, Can't access a certain directory due to restrictions.
While I have not tested this in Windows 7, on Windows 10, these were the steps that I took to make LiteIDE work
Installed Go to C:\Go
Added C:\Go\bin to PATH and made sure go was working from Command Line
This was the most important step for me. Defined GOPATH in an environment variable. In my case, it was C:\Users\vivek\Documents\Source\Go. I also made sure that there were three folders src, pkg and bin were created in GOPATH. At this point go env was showing me correct values for GOPATH and GOROOT. go get, go build and go install was working as well at this step.
Downloaded and unzipped LiteIDE to C:\liteide. Started LiteIDE and it worked out of the box for me. Make sure that GOPATH is seen correctly by LiteIDE by going to View > Manage GOPATH
Hope this helps. Good luck.
It's not a good idea to keep your projects in the GOROOT path, which per default (when installed using the MSI installer) is C:\Go. Always keep it separated from there. It also helps to avoid issues with updates.
Since Go projects are made up of packages which are organized in directory structures it is important to follow a few rules and keep the working space for your Go projects separated and clean.
In my opinion its best practice to create ONE working directory as the root for ALL your Go projects somewhere in your user space and stick to it.
One way to do this is to create a directory like "work" and set the environment variable GOPATH to it (e.g. C:\Users\Peter\Documents\work). Make sure to relog or restart your computer after your changes.
Upon certain operations Go will automatically create the directories bin, pkg and src below your GOPATH.
src contains your created or downloaded Go source files,
pkg contains your installed package objects, and
bin contains your installed executable files.
bin or pkg will automatically be created when you use the go install command to install a binary executable or a package. It's important to understand that these are files that are not part of the Go installation.
src, if it does not yet exist, will automatically be created the first time you issue a go get command or in case of LiteIDE, the first time you create a new Go1 Command Project or Go1 Package Project. Watch the "Location:" field on the dialog box, it should include your path defined in GOPATH followed by \src (e.g. C:\Users\Peter\Documents\work\src).
In the name field enter the path you want to use for your project. If you plan to track the development of your project on Github (or other repo) it's common practice to include the path to the Git repo in your source path (e.g. github.com/petergloor/hello-go).
Of course you can use any other structure to organize your projects as long you make sure they fall below the src directory in your GOPATH.
For more information about Go workspaces read https://golang.org/doc/code.html#Workspaces.
A final note about the GOROOT environment variable. Dont explicitly set this if you install Go in C:\Go. It's enough to include C:\Go\bin in your path and to set GOPATH. GOROOT is only needed in case Go is installed at another location.
I also had this problem first, but after completing the installation process, I succeeded.
Step 1:
Run (Ctrl+R) -> run target, request build first.
BuildAndRun(Ctrl+F7) -> build and run target
FileRun(Alt+F6) -> go run
step 2:
Check Config via this URL:
https://www.goinggo.net/2013/06/installing-go-gocode-gdb-and-liteide.html
Try setting up the GOROOT to the directory where go was installed. It worked for me.
Do you have 'Install' keyword in your project name? Try remove it.
You have to setup LiteIDE variables correctly (if there are not by default).
Please, check two options:
Go to Settings → "Manage GOPATH"
Options → LiteEnv (there are
environment definitions files). Just double click on someone and
setup Go environment variables.
I'm not sure how this works, but it worked in my case. I got this idea from this video on Youtube-Chris Hawkes
Open LiteIDE.
Click File---New.
Select "Go1 Command Project".
Browse the desired path.
Select the desired folder.
Name the folder and click Ok.
Now, you will be able to see a "main.go" file opened in the IDE.
Write whatever code you want to run in this file with correct syntax, it will run.
The only problem with this is, whenever I create another ".go" source code file in the same folder, the same error is shown. So, you might have to edit this file every time, you try to write new code.
