Cannot verify the Arduino code because the installed library cannot be found

guisisi225 · January 25, 2024, 10:41pm

I installed a library using Sketch -> Include library -> Manage libraries and it was installed successfully. When I included it in the code and try to compile(verify), it said cannot find the file.

Solved.
My environmental path in "preference" contains a Chinese folder name and cannot be detected by my computer. I tried to use another path with the full English folder name and it was solved.

Hopefully, my case can help you.

Thanks for taking the time to share this valuable information @guisisi225.

The Arduino developers are tracking this bug here:

"No such file or directory" error when library's path contains post-ASCII characters

topic: code type: imperfection

### Describe the problem If a library is installed under a path that contains… Cyrillic characters, Arduino CLI is unable to discover it. Compilation of sketches with an `#include` directive for a header file of a valid library fails with a "`No such file or directory`" error. ### To reproduce ```text $ arduino-cli version arduino-cli.exe Version: git-snapshot Commit: 4b70e023 Date: 2023-01-31T03:19:27Z $ export ARDUINO_DIRECTORIES_USER="/tmp/arduino-cli-directories/мікроконтролер" $ arduino-cli lib install Arduino_JSON [...] $ mkdir /tmp/FooSketch $ printf "#include <Arduino_JSON.h>\nvoid setup() {}\nvoid loop() {}" > /tmp/FooSketch/FooSketch.ino $ arduino-cli compile --fqbn arduino:avr:uno /tmp/FooSketch/FooSketch.ino C:\Users\per\AppData\Local\Temp\FooSketch\FooSketch.ino:1:10: fatal error: Arduino_JSON.h: No such file or directory #include <Arduino_JSON.h> ^~~~~~~~~~~~~~~~ compilation terminated. Used library Version Path Arduino_JSON 0.2.0 C:\Users\per\AppData\Local\Temp\arduino-cli-directories\мікроконтролер\libraries\Arduino_JSON Used platform Version Path arduino:avr 1.8.6 C:\Users\per\AppData\Local\Arduino15\packages\arduino\hardware\avr\1.8.6 Error during build: exit status 1 ``` ### Expected behavior Any path supported by the file system is also supported by the library discovery system ### Arduino CLI version #### Original report Arduino IDE 1.8.10 #### Last verified with 4b70e023 ### Operating system Windows ### Operating system version - 10 - 11 ### Additional context The issue is not specific to Cyrillic. For example, it also occurs with a folder named `文` or `Κώστας`. --- The fault only occurs on Windows. I am not able to reproduce it on Ubuntu 22.04 or macOS Ventura machines. --- After changing system's locale from English to Bulgarian (win1251) + restart, the compilation succeeded. Unfortunately this is not viable solution, because we have many computers (>150) and changing system locale requires admin privileges. My suggestion is that the IDE is not using the unicode version of the API when searching for libraries? --- This is more likely to occur for those using [Microsoft **Onedrive**](https://en.wikipedia.org/wiki/OneDrive) because the default location of the sketchbook is: ```text C:\Users\<username>\OneDrive\<localized "Documents">\Arduino ``` The `<localized "Documents">` in the path above is a placeholder the word "Documents" localized for the user's locale (e.g., `文档` or `Документы`) #### Additional reports - https://forum.arduino.cc/t/wemos-d1-mini-upload-problem/1084371 - https://forum.arduino.cc/t/no-such-file-or-directory-but-i-already-had-this-file/961118 - https://forum.arduino.cc/t/fatal-error-adafruit-neopixel-h-no-such-file-or-directory-but-i-have-it/1070069/15 - https://forum.arduino.cc/t/library-gives-error/1089633 - https://forum.arduino.cc/t/except-for-the-available-libraries-i-cant-use-other-libraries-even-though-i-have-downloaded-them/1092556 - https://forum.arduino.cc/t/compilation-error-due-to-library-hpp-file-not-being-detected/1127096 - https://forum.arduino.cc/t/which-arduino-nano-clone-i-have/1192347/11 - https://forum.arduino.cc/t/cannot-verify-the-arduino-code-because-the-installed-library-cannot-be-found/1215989 ### Issue checklist - [X] I searched for previous reports in [the issue tracker](https://github.com/arduino/arduino-cli/issues?q=) - [X] I verified the problem still occurs when using the [nightly build](https://arduino.github.io/arduino-cli/dev/installation/#nightly-builds) - [X] My report contains all necessary details
