I'd like to fix this but I don't know what to do.
I will work on later. Please let me know if you have any solutions.

+E0178: r##"
+In types, the `+` type operator has low precedence, so it is often necessary
+to use parentheses.
+
+For example:
+
+```compile_fail,E0178
+trait Foo {}
+
+struct Bar<'a> {
+    w: &'a Foo + Copy,   // error, use &'a (Foo + Copy)
+    x: &'a Foo + 'a,     // error, use &'a (Foo + 'a)
+    y: &'a mut Foo + 'a, // error, use &'a mut (Foo + 'a)
+    z: fn() -> Foo + 'a, // error, use fn() -> (Foo + 'a)
+}
+```

+"##,
+
+E0536: r##"
+The `not` cfg-predicate was malformed.
+
+Erroneous code example:
+
+```compile_fail,E0536
+#[cfg(not())] // error: expected 1 cfg-pattern
+pub fn something() {}
+
+pub fn main() {}
+```
+
+The `not` predicate expects one cfg-pattern. Example:
+
+```
+#[cfg(not(target_os = "linux"))] // ok!
+pub fn something() {}
+
+pub fn main() {}
+```
+
+For more information about the cfg attribute, read:
+https://doc.rust-lang.org/reference.html#conditional-compilation
+"##,
+
+E0537: r##"
+An unknown predicate was used inside the `cfg` attribute.
+
+Erroneous code example:
+
+```compile_fail,E0537
+#[cfg(unknown())] // error: invalid predicate `unknown`
+pub fn something() {}
+
+pub fn main() {}
+```
+
+The `cfg` attribute supports only three kinds of predicates:
+
+ * any
+ * all
+ * not
+
+Example:
+
+```
+#[cfg(not(target_os = "linux"))] // ok!
+pub fn something() {}
+
+pub fn main() {}
+```
+
+For more information about the cfg attribute, read:
+https://doc.rust-lang.org/reference.html#conditional-compilation
+"##,
+
+E0538: r##"
+Attribute contains same meta item more than once.
+
+Erroneous code example:
+
+```compile_fail,E0538
+#[deprecated(
+    since="1.0.0",
+    note="First deprecation note.",
+    note="Second deprecation note." // error: multiple same meta item
+)]
+fn deprecated_function() {}
+```
+
+Meta items are the key-value pairs inside of an attribute. Each key may only be
+used once in each attribute.
+
+To fix the problem, remove all but one of the meta items with the same key.
+
+Example:
+
+```
+#[deprecated(
+    since="1.0.0",
+    note="First deprecation note."
+)]
+fn deprecated_function() {}
+```
+"##,
+
+E0541: r##"
+An unknown meta item was used.
+
+Erroneous code example:
+
+```compile_fail,E0541
+#[deprecated(
+    since="1.0.0",
+    // error: unknown meta item
+    reason="Example invalid meta item. Should be 'note'")
+]
+fn deprecated_function() {}
+```
+
+Meta items are the key-value pairs inside of an attribute. The keys provided
+must be one of the valid keys for the specified attribute.
+
+To fix the problem, either remove the unknown meta item, or rename it if you
+provided the wrong name.
+
+In the erroneous code example above, the wrong name was provided, so changing
+to a correct one it will fix the error. Example:
+
+```
+#[deprecated(
+    since="1.0.0",
+    note="This is a valid meta item for the deprecated attribute."
+)]
+fn deprecated_function() {}
+```
+"##,
+
+E0552: r##"
+A unrecognized representation attribute was used.
+
+Erroneous code example:
+
+```compile_fail,E0552
+#[repr(D)] // error: unrecognized representation hint
+struct MyStruct {
+    my_field: usize
+}
+```
+
+You can use a `repr` attribute to tell the compiler how you want a struct or
+enum to be laid out in memory.
+
+Make sure you're using one of the supported options:
+
+```
+#[repr(C)] // ok!
+struct MyStruct {
+    my_field: usize
+}
+```
+
+For more information about specifying representations, see the ["Alternative
+Representations" section] of the Rustonomicon.

+["Alternative Representations" section]: https://doc.rust-lang.org/nomicon/other-reprs.html
+"##,
+
+E0554: r##"
+Feature attributes are only allowed on the nightly release channel. Stable or
+beta compilers will not comply.
+
+Example of erroneous code (on a stable compiler):
+
+```ignore (depends on release channel)
+#![feature(non_ascii_idents)] // error: #![feature] may not be used on the
+                              //        stable release channel
+```
+
+If you need the feature, make sure to use a nightly release of the compiler
+(but be warned that the feature may be removed or altered in the future).
+"##,
+
+E0557: r##"
+A feature attribute named a feature that has been removed.
+
+Erroneous code example:
+
+```compile_fail,E0557
+#![feature(managed_boxes)] // error: feature has been removed
+```
+
+Delete the offending feature attribute.
+"##,
+
+E0565: r##"
+A literal was used in a built-in attribute that doesn't support literals.
+
+Erroneous code example:
+
+```ignore (compile_fail not working here; see Issue #43707)
+#[inline("always")] // error: unsupported literal
+pub fn something() {}
+```
+
+Literals in attributes are new and largely unsupported in built-in attributes.
+Work to support literals where appropriate is ongoing. Try using an unquoted
+name instead:
+
+```
+#[inline(always)]
+pub fn something() {}
+```
+"##,
+
+E0583: r##"
+A file wasn't found for an out-of-line module.
+
+Erroneous code example:
+
+```ignore (compile_fail not working here; see Issue #43707)
+mod file_that_doesnt_exist; // error: file not found for module
+
+fn main() {}
+```
+
+Please be sure that a file corresponding to the module exists. If you
+want to use a module named `file_that_doesnt_exist`, you need to have a file
+named `file_that_doesnt_exist.rs` or `file_that_doesnt_exist/mod.rs` in the
+same directory.
+"##,
+
+E0585: r##"
+A documentation comment that doesn't document anything was found.
+
+Erroneous code example:
+
+```compile_fail,E0585
+fn main() {
+    // The following doc comment will fail:
+    /// This is a useless doc comment!
+}
+```
+
+Documentation comments need to be followed by items, including functions,
+types, modules, etc. Examples:
+
+```
+/// I'm documenting the following struct:
+struct Foo;
+
+/// I'm documenting the following function:
+fn foo() {}
+```
+"##,
+
+E0586: r##"
+An inclusive range was used with no end.
+
+Erroneous code example:
+
+```compile_fail,E0586
+fn main() {
+    let tmp = vec![0, 1, 2, 3, 4, 4, 3, 3, 2, 1];
+    let x = &tmp[1..=]; // error: inclusive range was used with no end
+}
+```
+
+An inclusive range needs an end in order to *include* it. If you just need a
+start and no end, use a non-inclusive range (with `..`):
+
+```
+fn main() {
+    let tmp = vec![0, 1, 2, 3, 4, 4, 3, 3, 2, 1];
+    let x = &tmp[1..]; // ok!
+}
+```
+
+Or put an end to your inclusive range:
+
+```
+fn main() {
+    let tmp = vec![0, 1, 2, 3, 4, 4, 3, 3, 2, 1];
+    let x = &tmp[1..=3]; // ok!
+}
+```
+"##,
+
+E0589: r##"
+The value of `N` that was specified for `repr(align(N))` was not a power
+of two, or was greater than 2^29.
+
+```compile_fail,E0589
+#[repr(align(15))] // error: invalid `repr(align)` attribute: not a power of two
+enum Foo {
+    Bar(u64),
+}
+```
+"##,
+
+E0658: r##"
+An unstable feature was used.
+
+Erroneous code example:
+
+```compile_fail,E658
+#[repr(u128)] // error: use of unstable library feature 'repr128'
+enum Foo {
+    Bar(u64),
+}
+```
+
+If you're using a stable or a beta version of rustc, you won't be able to use
+any unstable features. In order to do so, please switch to a nightly version of
+rustc (by using rustup).
+
+If you're using a nightly version of rustc, just add the corresponding feature
+to be able to use it:
+
+```
+#![feature(repr128)]
+
+#[repr(u128)] // ok!
+enum Foo {
+    Bar(u64),
+}
+```
+"##,
+
+E0633: r##"
+The `unwind` attribute was malformed.
+
+Erroneous code example:
+
+```ignore (compile_fail not working here; see Issue #43707)
+#[unwind()] // error: expected one argument
+pub extern fn something() {}
+
+fn main() {}
+```
+
+The `#[unwind]` attribute should be used as follows:
+
+- `#[unwind(aborts)]` -- specifies that if a non-Rust ABI function
+  should abort the process if it attempts to unwind. This is the safer
+  and preferred option.
+
+- `#[unwind(allowed)]` -- specifies that a non-Rust ABI function
+  should be allowed to unwind. This can easily result in Undefined
+  Behavior (UB), so be careful.
+
+NB. The default behavior here is "allowed", but this is unspecified
+and likely to change in the future.
+
+"##,
+
+E0705: r##"
+A `#![feature]` attribute was declared for a feature that is stable in
+the current edition, but not in all editions.
+
+Erroneous code example:
+
+```ignore (limited to a warning during 2018 edition development)
+#![feature(rust_2018_preview)]
+#![feature(test_2018_feature)] // error: the feature
+                               // `test_2018_feature` is
+                               // included in the Rust 2018 edition
+```
+
+"##,
+
+E0725: r##"
+A feature attribute named a feature that was disallowed in the compiler
+command line flags.
+
+Erroneous code example:
+
+```ignore (can't specify compiler flags from doctests)
+#![feature(never_type)] // error: the feature `never_type` is not in
+                        // the list of allowed features
+```
+
+Delete the offending feature attribute, or add it to the list of allowed
+features in the `-Z allow_features` flag.
