是否可以指定一個自定義的「lib /」分片安裝目錄？

Question

Crystal項目中Crystal shards的默認安裝目錄是「lib /」。是否可以自定義路徑？

Answer 1

看來你可以設置一個環境變量SHARDS_INSTALL_PATH。但是這並沒有記錄，應該小心處理。

爲什麼你需要不同的安裝目錄呢？

Answer 2

# This sets the install path when you do `crystal deps`. 
# It needs to be an absoluete path, not a relative path. 
export SHARDS_INSTALL_PATH="$PWD/my/dir" 

# This is needed for the Crystal compiler to the find the shards. 
# The Crystal compiler does not use SHARDS_INSTAL_PATH. 
# Unlike SHARDS_INSTALL_PATH, it can be a relative path. 
# You must also specify the place for the Crystal source directory 
# in order to find the Standard Lib .cr files: 
export CRYSTAL_PATH="$SHARDS_INSTALL_PATH:the/crystal/src" 

# Now you can do: 
crystal deps     # uses SHARDS_INSTALL_PATH 
crystal build src/my-file.cr # uses CRYSTAL_PATH

注意：由於前面陳述的Johannes Müller，這是無證的。
